Pilar leiomyoma (Q96729): Difference between revisions

Pilar leiomyoma is a benign cutaneous tumour derived from the arrector pili muscle of the pilosebaceous follicle. Solitary lesions may develop anywhere on hair-bearing skin, particularly the trunk and limbs. Multiple lesions have a predilection for the face, back and extensor surfaces of the extremities and are often painful. Multiple pilar leiomyomata may be familial with autosomal dominant inheritance and associated with uterine leiomyomata in women, and, in some pedigrees, renal carcinoma (HLRCC; Hereditary leiomyomatosis with renal cell cancer).
