Infantile myofibromatosis is a rare fibrous tumor of infancy that can be solitary or multiple. Although most of the cases are limited to the skin, in some instances systemic involvement can be present. Solitary tumors limited to the skin usually present a good prognosis with spontaneous regression. We performed a retrospective observational review of the clinical and pathologic characteristics of nine patients diagnosed as having infantile myofibromatosis, followed during a 10-year period in a Pediatric Dermatology Department.
