Neuromuscular hamartomas of the head and neck.
The neuromuscular hamartoma (also referred to as the neuromuscular choristoma or benign triton tumor) is a rare developmental lesion composed of mature elements of both striated muscle and nerve. To date, less than 20 cases have been reported in the English language literature. The majority of these have involved large nerves, such as the sciatic or brachial plexus, but cutaneous lesions have also been reported. We report 2 cases that involve the head and neck and that are among the few described in this location. The majority of cases have been described in infants and young children. However, 1 of our cases (and at least 1 previously reported case) occurred in an adult. While surgical excision has been the most widely used form of therapy, a few cases have been complicated by and/or associated with a second lesion, such as a fibromatosis or lymphangioma.
