Infantile myofibromatosis is a very rare tumor in childhood and infancy. The authors report on a 4-year-old boy who presented with two relapses of initially multifocal infantile myofibromatosis without visceral involvement. The lesions of the skull and the abdomen were excised while osteolytic lesions of the limbs were not treated. Chemotherapy or radiation have not been applicated. Three years after initial diagnosis there is no evidence for persistence or recurrence of the tumor.
