MULTIPLE CUTANEOUS NEUROMUSCULAR CHORISTOMAS - REPORT OF A CASE AND A REVIEW OF THE LITERATURE

We report a case of two neuromuscular choristomas occurring in separate cutaneous locations in a healthy 3-month-old infant. Both lesions had an identical histologic appearance and were composed of mature skeletal muscle cells admixed with nerve fibers. In all previous reports, neuromuscular choristoma has arisen in association with a major nerve, and most lesions have been solitary. The two separate cutaneous choristomas in this case suggest that this lesion may arise from the neuroectodermal-derived Schwann cell.
