Infantile myofibromatosis is a rare mesenchymal disorder characterized by the onset of nodules in the skin, striated muscles, bones, and, more rarely, visceral organs. Subcutaneous or soft tissue nodules commonly involve the skin of the head, neck, and trunk. Skeletal and muscular lesions occur in about 50% of patients. Lesions may be solitary or multicentric, and they may be present at birth or become apparent in early infancy or occasionally in adult life (summary by Arcangeli and Calista, 2006).
