title: Intramuscular myxoma of scalene muscle: a case report.
abstract: Intramuscular myxoma is a benign mesenchymal tumor that commonly occurs in the larger skeletal muscles, and is rare in the head and neck. A case of intramuscular myxoma in the scalene muscle is described. This is the first report of this tumor arising in that muscle. It is difficult to diagnose pre-operatively from clinical features, CT scan and ultrasonography of the neck because of the lack of characteristic manifestation or radiographic features. Intramuscular myxoma has an infiltrative tendency, so there are several reports of recurrence because of incomplete excision or enucleation. In our case no recurrence was observed for 4 years, since the tumor was removed with the muscle adherent to it.
