Recurrent infantile myofibromatosis in a 19-month-old boy presenting as ulcerated plaque

A 19-month-old boy presented to our department with ulcerated plaque on the right lumbar region. The lesion was known to have been growing for about 5 months. At another center 9 months prior to presenting to our department, the patient's parents reported a history of cutaneous nodules from the same lumbar region. Their total excision was performed, and the pathology report stated that it was infantile calcifying fibromatosis or nodular fasciitis. The patient was healthy with a nonsignificant, medical history including no use of medications, no known drug allergies, and no significant family history of disease.
