Plexiform fibrohistiocytic tumor of the foot: a case report.

Plexiform fibrohistiocytic tumors are rare, small, ill-defined, solitary masses found in the deep dermis or subcutaneous tissues. These tumors will ordinarily be slow-growing masses that almost solely occur in children and young adults. They have had a greater prevalence in the upper extremity than in the lower extremity, with limited reports of this lesion in the lower extremity. We report a small painful mass found in the central plantar heel of a 12-year-old male.
