Pediatric Dermatomyofibroma Case Series

Dermatomyofibroma (DMF), rare in the pediatric population, is a benign dermal tumor composed of myofibroblasts and fibroblasts. We identified 21 histologically confirmed cases of pediatric DMF from our institution's dermatopathology database. Most cases occurred in male children, were located on the neck, and were difficult to distinguish clinically from lesions such as dermatofibromas and cysts. Following chart review of seven patients who received dermatologic care at our institution, we report unusual presentations of DMF and describe post‐biopsy follow‐up evaluations.
