Intramuscular myxoma of the neck.

Intramuscular myxomas are extremely rare tumors in the neck. In reviewing the world literature, we found a total of five cases of intramuscular myxoma that occurred in the head and neck region. The purpose of this study is to report an unusual case of intramuscular myxomas that were found bilaterally in the digastric muscles of a girl who presented with a painless palpable mass in the neck.
