Benign tumours of cutaneous smooth muscle – http://id.who.int/icd/entity/570822911

Benign neoplasms derived from dermal smooth muscle. They present as dermal papules, nodules or plaques. The most common form is the pilar leiomyoma which arises from arrector pili muscle, located adjacent to hair follicles. Pilar leiomyomata normally present in adult life as solitary or multiple dermal papules (pilar leiomyomata); when multiple they are often familial and are characteristically painful. Cutaneous angioleiomyomata arise from smooth muscle within the walls of arteries and veins. Genital leiomyomata may arise from genital smooth muscle (labia majora or scrotum) or from areolar smooth muscle of the breast.
