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.
肌内黏液瘤是一种良性间叶组织肿瘤，常见于较大的骨骼肌，在头颈部罕见。本文描述了一例发生于斜角肌的肌内黏液瘤。这是该肿瘤在该肌肉中发生的首例报道。由于缺乏特征性表现或影像学特征，术前很难通过颈部的临床特征、CT扫描和超声检查进行诊断。肌内黏液瘤有浸润性倾向，因此有几例因切除或摘除不完全而复发的报道。在我们的病例中，由于肿瘤与其附着的肌肉一并切除，4年来未观察到复发。
