Clinical and Laboratory Observations

Infantile myofibromatosis (IM) is most commonly limited to cutaneous lesions that resolve spontaneously. However, generalized IM with visceral involvement, which has a reported mortality rate as high as 73%, has been successfully treated with a combination of methotrexate and vinblastine. Here we report the further efficacy of low-dose methotrexate and vinblastine in 2 pediatric patients with IM and visceral involvement and review the literature describing chemotherapy for these patients.
