Cutaneous leiomyomas

A leiomyoma is a benign tumour composed of smooth muscle. It is capable of arising wherever smooth muscle is present. One form of leiomyoma arises from uterine smooth muscle, and is otherwise known as uterine fibroids. Cutaneous leiomyomas may be classified into three types Familial cutaneous leiomyomatosis (FCL) is an autosomal dominant genetic disease. It presents with cutaneous and uterine leiomyomas and is associated with the development of renal cancer. Characteristic findings on physical examination See the Leiomyoma chapter for a description of leiomyomas Cutaneous leiomyoma Cutaneous leiomyomas or piloleiomyomas appear as small (0.5-2 cm) firm skin coloured nodules. They arise from the arrector pili muscles which are responsible for making hairs stand on end. Multiple lesions may develop, often in clusters and commonly in a segmental distribution Cutaneous Leiomyoma are rare benign tumors that derive from the proliferation of smooth muscle cells

  1. Tumors of the arrector pili muscles are well-circumscribed, smooth, firm, reddish-brown nodules ranging in size from 2-15 millimeters. The lesions can be solitary or multiple and usually involve the face, neck, trunk, and extremities. Pilar leiomyomas are the most common of the cutaneous types and the lesions are often multiple and painful
  2. A leiomyoma is an uncommon, benign tumour of smooth muscle. There are three types of cutaneous leiomyomas: piloleiomyomas, angioleiomyomas and genital leiomyomas. This classification reflects the most logical origin of the tumour, corresponding to the histologic or anatomic site where the leiomyomas are found
  3. Cutaneous leiomyomas may be the same color as the surrounding skin, or they may be darker. Some affected individuals have no cutaneous leiomyomas or only a few, but the growths tend to increase in size and number over time. Cutaneous leiomyomas are often more sensitive than the surrounding skin to cold or light touch, and may be painful
  4. Almost all patients with multiple skin leiomyomas have germline fumarate hydratase mutation (Arch Dermatol 2005;141:199) Back to top Home > Soft tissue > Cutaneous leiomyoma
  5. Dear Editor, Cutaneous leiomyomas (CL) are rare, benign smooth muscle tumors of the skin (1). There are 3 subtypes with different origins and histopathologic features: piloleiomyoma, genital leiomyoma, and angioleiomyoma (2). Pilar leiomyoma is the most common subtype originating from arrector pili muscles of pilosebaceous unit

Cutaneous leiomyomas, also called piloleiomyomas, are uncommon benign smooth muscle tumors derived from the arrector pili muscle, which is responsible for piloerection of hair follicles To the Editor: We have followed with interest the recent literature that advocates the use of fumurate hydratase (FH) immunohistochemistry in cutaneous leiomyomas to aid in the detection of patients with hereditary leiomyomatosis and renal cell carcinoma syndrome (HLRCC). 1,2 HLRCC (also known as Reed syndrome) is characterized by multiple leiomyomas, both cutaneous and uterine, with an. Hereditary leiomyomatosis and renal-cell cancer (HLRCC; Online Mendelian Inheritance in Man (OMIM) 150,800) is a syndrome characterized by the development of cutaneous and uterine leiomyomas and renal cancer. Multiple cutaneous and uterine leiomyomas (MCUL) was initially described in 1973 by Reed et al. as an autosomal dominant syndrome (1) Cutaneous leiomyomata appear as skin-colored to light brown papules or nodules distributed over the trunk and extremities, and occasionally on the face, and appear at a mean age of 30 years, increasing in size and number with age

Cutaneous leiomyomas are smooth muscle tumors that may arise sporadically or in association with an inherited cancer-related genodermatosis. Leiomyomas may be severely painful, and current management is generally unsatisfactory Cutaneous leiomyomas are benign soft-tissue neoplasms that arise from smooth muscle (arrector pili). The arrector pili muscle contracts in response to cold, most commonly, or to fear or pleasure,.. Background: Cutaneous leiomyomas are benign smooth muscle tumors that comprise three distinct types such as piloleimyoma, angioleiomyoma, and genital leiomyoma.Aim: The objective of this study was to report a series of cases seen in last 8 years in a tertiary care hospital in north India and to discuss their clinicopathologic findings.Material and Methods: Paraffin-embedded blocks of cases. Hereditary leiomyomatosis and renal cell cancer (HLRCC) is a condition that causes benign tumors of smooth muscle tissue in the skin (cutaneous leiomyomas) and in the uterus in females (uterine leiomyomas, or fibroids). The condition also increases the risk of kidney cancer. Signs and symptoms usually begin in adulthood as skin growths appear on the torso, arms, legs, and occasionally on the face

Multiple cutaneous leiomyomas, also known as Pilar leiomyomas, arise from the arrectores pilorum muscles, and are made up of a poorly circumscribed proliferation of haphazardly arranged smooth muscle fibers located in the dermis that appear to infiltrate the surrounding tissue and may extend into the subcutis Cutaneous Leiomyomas. Cutaneous leiomyomas present as firm papules or nodules that appear pink or reddish-brown. These lesions usually appear on the trunk and the extremities and, occasionally, on the face. These lesions occur at a mean age of 25 years (age range, 10-47 y) and tend to increase in size and number with age Familial cutaneous leiomyomatosis is a two-hit condition associated with renal cell cancer of characteristic histopathology.

FH tumor predisposition syndrome is characterized by cutaneous leiomyomata, uterine leiomyomata (fibroids), and/or renal tumors. Pheochromocytoma and paraganglioma have also been described in a small number of families. Cutaneous leiomyomata appear as skin-colored to light brown papules or nodules distributed over the trunk and extremities, and occasionally on the face, and appear at a mean. Cutaneous leiomyomas are rare, benign tumors of the skin, which are present in multiple disseminated, segmental or solitary forms. The pathogenesis of segmental cutaneous leiomyomatosis is not yet fully known. Two types of segmental manifestation of the autosomal dominantly inherited disease are postulated

Cutaneous leiomyomas are rare, benign, smooth muscle tumors that are subcategorized based on the origin of the smooth muscle within the tumor. The most common type of cutaneous leiomyomas, angioleiomyomas, arise from the tunica media of blood vessels. The 2 other subtypes, piloleiomyomas and genital leiomyomas, arise from the arrector pili. Multiple cutaneous and uterine leiomyomas (MCUL) was initially described in 1973 by Reed et al. as an autosomal dominant syndrome (1). In 2001, two families were reported with renal cancer as well as multiple cutaneous and uterine leiomyomas by Aaltonen et al. and termed HLRCC (2). In their report, they speculated that this syndrome is a.

To our knowledge, only few cases of one-sided nipple leiomyomas have been reported, but two-sided nipple leiomyomas have not been.

Cutaneous leiomyomas are also rare tumors in humans. The most common form, leiomyoma cutis (piloleiomyoma), originates from smooth muscle cells of the arrector pili mus-cles. This form is most common in young adults. Interest-ingly, a familial form of multiple cutaneous leiomyomas also exists in humans.5 In affected individuals, the tumors ma hereditary leiomyomatosis and renal cell cancer (cutaneous & uterine leiomyomas) Symptoms. skin: pain, uterus: bulky.

Cutaneous leiomyomas are rare, benign soft tissue tumors arising from smooth muscles of the skin and comprise of three distinct subtypes, namely piloleiomyoma, angioleiomyoma and genital leiomyoma. Piloleiomyomas can present as solitary form, multiple disseminated and zosteriform or segmental forms

Test description. This test analyzes the FH gene associated with hereditary leiomyomatosis and renal cell cancer (HLRCC).HLRCC is characterized by cutaneous leiomyomas, uterine leiomyomas, and/or renal tumors. Individuals with HLRCC are also at risk of having a child with autosomal recessive fumarate hydratase deficiency (FHD) if their partner also carries an FH pathogenic variant Cutaneous leiomyomas are benign tumors originating generally from the smooth muscles located at various sites of the body. They are categorized according to the tissue origin as follows: pilar leiomyoma, angioleiomyoma, and genital leiomyoma.

Cutaneous Leiomyomas Article - StatPearl

  1. Multiple cutaneous leiomyomas has recently been added to the list of cancer-susceptibility syndromes that may first present in the skin. These tumors may represent manifestations of multiple cutaneous and uterine leiomyomatosis (MCUL) syndrome or leiomyomatosis renal cell cancer (HLRCC) syndrome, which are closely related, if not the same entity
  2. Cutaneous leiomyomas are benign neoplasms with smooth muscle differentiation, which are classified as piloleiomyomas, angioleiomyomas and genital leiomyomas according to their origin. Piloleiomyomas represent the most common type of cutaneous leiomyomas and mainly occur as multiple tumors,.
  3. Leiomyomas are benign smooth muscle tumors, which can arise from the arrector pili muscle (pilar leiomyomas), from the media of blood vessels (angioleiomyomas), or from the smooth muscle of the scrotum, labia majora or nipples (genital leiomyomas). The cutaneous symplastic leiomyoma is a rarely reported variant of the pilar leiomyoma
  4. Leiomyomas are benign tumors of smooth muscle origin. They are most commonly found in the uterus, but cutaneous leiomyomas may be occasionally present in the extremities and cause pain secondary to mass effect. Few studies have reported leiomyoma of the foot, and leiomyoma of the heel is particularly rare. We present a case of a 41-year-old female who presented to our clinic for a tender.
  5. Multiple cutaneous leiomyomas, also known as Pilar leiomyomas, [2] arise from the arrectores pilorum muscles, and are made up of a poorly circumscribed proliferation of haphazardly arranged smooth muscle fibers located in the dermis that appear to infiltrate the surrounding tissue and may extend into the subcutis. [2
  6. Cutaneous leiomyomas arise from smooth muscle bundles within the arrector pili or from vascular smooth muscle. Tumors arising from arrector pili are more superficially located in the dermis and less well circumscribed. In leiomyomas, bundles of eosinophilic cells with ample cytoplasm and blunted,.
  7. Although Verneuil described a case of multiple cutaneous leiomyomas in a cadaver in 1858, and Duhring in 1873 and Kosinski in 1874, cases of undoubted multiple leiomyomas which they mistook for neuromas, the disease did not become well known until 1880, when Besnier published his comprehensive paper

  1. Cutaneous leiomyomas are highly penetrant in HLRCC families. In a study that reported on the second cohort of North American HLRCC families evaluated by the National Cancer Institute, cutaneous.
  2. ant syndrome of multiple cutaneous and uterine leiomyomatosis (MCUL).Forty‐five distinct FH mutations have been identified in 76 of 89 (85%) reported probands with skin leiomyomas. This suggests that MCUL is a genetically homogeneous condition and that most patients presenting.
  3. Complete surgical resection of multiple cutaneous leiomyomas prevented the disease's recurrence. The immediate reconstruction of the resultant full-thickness defect with artificial dermis ensured uneventful wound healing, resulting in optimal functional and esthetic outcome and total relief from leiomyoma-associated discomfort
  4. In a retrospective study of more than 9,000 feline cutaneous tumors, 6.6% were non-neoplastic and 93.4% were neoplastic, of which 52.7% were considered malignant. The ten most common skin tumor types accounted for 80.7% of cases, with the four most common being basilar epithelial tumor, fibrosarcoma, squamous cell carcinoma and mast cell tumor.
  5. Cutaneous leiomyomas that occur in association with HLRCC typically present early and are multiple. Thus far, the presence of certain morphologic features (large eosinophilic macronucleoli surrounded by halos and eosinophilic cytoplasmic inclusions) in RCC and uterine leiomyomas has been shown to correlate with FH mutations
  6. Leiomyomas are benign smooth muscle neoplasms commonly found in the uterus and gastrointestinal tract. Cutaneous leiomyomas are a subcategory of leiomyomas comprising less than 5% of the total number of these tumors. Within this category are genital leiomyomas, which can arise from the smooth muscle of the tunica dartos, areola, or vulva

Cutaneous leiomyomas can develop wherever smooth muscles are present, but malignant transformation probably does not occur. The importance of correct diagnosis of cutaneous leiomyoma lies is the association of multiple cutaneous leiomyomas with uterine fibroids and papillary renal cell carcinoma in what is known as Reed syndrome, or hereditary. Randomized, double-blind, placebo-controlled pilot study conducted from January 5, 2009, to March 27, 2014. The setting was a single-center study at the National Institutes of Health among participants 18 years or older with cutaneous leiomyomas characterized by pain at least once weekly and pain of at least 4 on a pain scale ranging from 0 to 10 None of the evaluated morphologic features showed any association with leiomyomas in HLRCC. Loss of FH immunohistochemical expression in cutaneous leiomyomas is a sensitive and specific marker for detection of HLRCC, thus suggesting a role for prospective FH IHC in patients with these tumors to screen for HLRCC leiomyomas, and angioleiomyomas [1]. Previous studies have showed that 70-98% of the female cutaneous leiomyoma patients also have synchronous uterine leiomyomas [2]. Furthermore, the synchronous appearance of uterine and cutaneous leiomyomas have been associated with an increased risk of renal cell cancer of papillary subtype [3]. 2 contrast, cutaneous leiomyomas are present in all patients. Eighty-nine percent of patients report lesion-associatedpain,characteristicallyprecipitated by heat/cold, trauma, or light touch.2 Cutaneous leiomyomas do not resolve spontane-ously; thus, symptoms should guide treatment. In mild cases, avoidance of painful triggers may be sufficient

It was once believed that leiomyosarcomas originated from small, benign, smooth muscle tumors, known as leiomyomas. The occurrence of a malignant tumor from a leiomyoma is now believed to be extremely rare; Primary Cutaneous Leiomyosarcoma (PCL) is a highly-infrequent malignant tumor affecting the skin Multiple Cutaneous and Uterine Leiomyomas Associated with Gastric Gist Manisha Lamba, Shailendra Verma, Robert Prokopetz, Tadeusz A.

Usually, they are firm cutaneous masses. Leiomyomas are small and tend to be limited to the dermis, whereas leiomyosarcomas are larger and most arise from (or extend into) the subcutaneous fat. The behavior of malignant smooth muscle tumors remains poorly defined. Complete excision is the treatment of choice for both leiomyomas and leiomyosarcomas Stewart EA, Morton CC.

Mayo Clinic proceedings. 2015 Jul 1;90(7):990. https://doi.org/10.1016/j.mayocp.2015.04.01 Summary Cutaneous leiomyomas are rare benign tumours of the skin, which present in multiple disseminated, segmental or solitary forms. The pathogenesis of segmental cutaneous leiomyomatosis is not yet fully known. Most recently two types of segmental manifestation of autosomal dominant inherited diseases were postulated. Type 1 reflects heterozygosity for the underlying mutation with a. Cutaneous leiomyomas have been reported in 76-100% of patients with HLRCC [8, 13]. The mean age of onset of cutaneous leiomyomas in the context of HLRCC is 25 years [10, 14], and 60-100% of FH germline mutation carriers over the age of 40 are reported to have cutaneous leiomyomas [8, 13]

Leiomyoma is a benign smooth muscle (myometrial) tumor, most commonly found in the uterus. Classification Leiomyoma is classified by location: uterine leiomyoma cervical leiomyoma leiomyoma of the urinary bladder urethral leiomyoma solita.. cutaneous nodulesyleiomyomas, uterine leiomyomas, and renal cell cancer were considered affected. The affection status of individual FAM-1yIII-10 with bladder cancer was scored as unknown. Probabilities for phenocopies were set to 0.20 for uterine leiomyomas, 0.00001 for the renal cell cancer phenotype, and 0.002 for cutaneous leiomyomatosis

Reed syndrome is a rare autosomal dominant disorder with a genetic defect in the fumarate hydratase. Patients with Reed syndrome have multiple cutaneous leiomyomas, uterine leiomyomas or leiomyosarcomas with increased risk of renal carcinoma.The current study presented a 57-year-old female with multiple cutaneous and uterine leiomyomatosis with a positive family history Cutaneous leiomyomas, rare benign tumors originating from the arrector pili muscle of the hair follicle, can be associated with the common uterine fibroids in a syndrome called multiple cutaneous and uterine leiomyomas. Multiple cutaneous and uterine leiomyomas are inherited as an autosomal dominant trait, providing an excellent opportunity for the study of the common non-Mendelian. Of families with HLRCC, 62% (13/21) had renal cancer and 76% (16/21) cutaneous leiomyomas. Of women FH mutation carriers from 16 families, 100% (22/22) had uterine fibroids. Our study shows that expression of cutaneous manifestations in HLRCC ranges from absent to mild to severe cutaneous leiomyomas A 49-year-old woman with cutaneous and uterine leiomyomas, flank pain and a family history of hereditary leiomyomatosis and renal cell cancer (HLRCC) syndrome sought genetic testing. She was found to harbour a fumarate hydratase (FH) genetic mutation and a previously undetected renal tumour. The patient underwent radical nephrectomy, and remains well at follow-up. HLRCC syndrome is a rare.

Cutaneous leiomyomas are rare, benign tumors of the skin, which can present in multiple disseminated, segmental or solitary forms. They are usually painful. Various modalities have been used to relieve pain in such lesions. We present two different types of cutaneous leiomyoma. of pain in the lesion after exposure to cold ambi leiomyoma [li″o-mi-o´mah] a benign tumor derived from smooth muscle, most often of the uterus (leiomyoma uteri). bizarre leiomyoma epithelioid leiomyoma. leiomyoma cu´tis one arising from cutaneous or subcutaneous smooth muscle fibers, found singly or multiply, usually as lesions arising from arrectores pilorum muscles; it may also occur as a. The cutaneous leiomyomas most commonly manifest as piloleiomyoma, which present clinically as solitary or multiple painful tumors (leiomyomatosis). Rarely, these may present in a disseminated or zosteriform/segmental distribution. We report an unusual case of cutaneous leiomyomatosis characterized by multiple scattered papulonodular lesions.

Cutaneous leiomyomas are rare neoplasms, and their exact incidence is unknown. One general surgical pathology practice reported the incidence to be as low as 0.04% in approximately 85,000 cases. 5 Cutaneous leiomyomas comprise approximately 5% of all leiomyomas. Solitary occurrence is more common than generalized. Multiple cutaneous piloleiomyomas are rare, painful and difficult-to-treat benign tumors originating in the arrectorespiloru

Clinical Features of Multiple Cutaneous and Uterine

Cutaneous leiomyomas, visceral tumors, locus 1q42.3-43, HLRC gene, fumarate hydratase Definition Familial leiomyomatosis is defined as the occurrence of multiple cutaneous leiomyomas within several members of a family. The tumours are considered to arise from the arrector pil While cutaneous leiomyomas can be painful and may require treatment, surveillance for RCC remains the higher priority. FH-related RCC is known to have a poor prognosis, as was the case for our patient. Muller et al. found that the lifetime risk of developing RCC in French FH pathogenic variant carriers is 19% - Cutaneous leiomyomas with histolopathologic features of uterine symplastic leiomyoma (USL) have also been reported [17,18]. Symplastic leiomyoma is an atypical uterine leiomyoma with cytologic atypia [19]. - Associated morbidity may be due to spontaneou solitary leiomyomas. Hereditary multiple cutaneous leiomy-omatosis is a tumor predisposition syndrome character-ized by multiple cutaneous and uterine leiomyomas and an increased risk of developing renal cancer [ ]. Multiple cutaneous and uterine leiomyomatosis, also known as Reed s syndrome, is an autosomal dominant genetic condition [ ] Cutaneous leiomyomas. An important goal of treatment for patients with cutaneous leiomyomas is to alleviate pain in these benign lesions. Medications, such as nifedipine, gabapentin, doxasozin, phenoxybenzamine, hyoscine, hydrobromide, and nitroglycerin have been used. 52 Single leiomyomas may be removed surgically

UpToDat

Leiomyoma is a benign tumour commonly encountered in the genitourinary and gastrointestinal organs in adults. Cutaneous leiomyomas are rare benign tumors arising from the arrector pili muscle of hair follicles. Cutaneous leiomyomas are more likely to occur in adults than in children. We describe a case of a 10-year-old female who presented with multiple, firm, red‑brown masses on the back Cutaneous leiomyomas are rare, benign smooth muscle tumors, characterized by painful nodules in most of the cases. They can occur in multiple disseminated, segmental or zosteriform and solitary forms. Segmental or zosteriform leiomyoma can occur either alone (Type I), or with scattered nonsegmental lesions elsewhere (Type II); the latter. Cutaneous leiomyomas usually present at an average age of 25 (range 10 to 47 years), and tend to increase in size and number with age. Uterine leiomyomas have been reported in 77% of women with HLRCC and appear at an average age of 30 (range 18 to 52 years) with symptoms preceding discovery. Fibroids tend to be numerous and large with earlier.
