Intramuscular myxoma of the nasal vestibule.

Intramuscular myxoma is an uncommon benign soft tissue neoplasm and a distinct histopathological entity within the heterogeneous group of myxomas. The most common localizations are the gluteal muscles and the muscles of the thigh. We report on a case of a myxoma within the mimetic muscles of the nasal and mouth region in a 52-year-old man. The tumor was surgically removed and the patient is free of recurrence or complications 8 months after treatment. The clinical and pathologic features of this lesion are presented. The head and neck region is an uncommon site of presentation for intramuscular myxoma with only 13 documented cases in the available literature. To the very best of our knowledge, there is no report of this neoplasm located within the nasal and oral mimetic muscles. Copyright (c) 2009 Elsevier Ireland Ltd. All rights reserved.
