Cutaneous neuromuscular choristoma: Case report and review of the literature

Neuromuscular choristoma, also known as benign triton tumor, is an uncommon developmental tumor composed of skeletal muscle and neural elements. The majority of cases reported have occurred in infants and have been generally associated with a large nerve, such as the brachial plexus or sciatic nerve. To date, only three cases of cutaneous lesions have been reported in the English literature. We describe a 28-year-old female presented with a soft, pedunculated papule on the presternal region since birth and review the literature of neuromuscular choristoma.
