摘要

局限性肌炎(focal myositis)為一種骨骼肌之良性及發炎性假性腫瘤。此疾病並不常見，發生在頸部者，更為少見。本科經驗1例30歲男性病患，臨床表現為一持續約兩星期之左頸部疼痛腫塊，經抗生素治療沒有反應之後，實行探查術並予切片，結果顯示為左側胸鎖乳突肌之局限性肌炎。此疾病之致病原因迄今雖仍不甚明瞭，但為一自癒性疾病，故並不需手術切除治療。

Focal myositis is a benign inflammatory pseudotumor of the skeletal muscle. It manifests by marked myopathic changes of the muscle fibers, interstitial fibrosis, and lymphocytic infiltration.
We encountered such a case in a 30-year old male with 2-week history of fever and a painful, left side-neck swelling. He failed to respond to antibiotic therapy and required an incisional biopsy of the sternocleidomastoid muscle, which revealed focal myositis.
This lesion must be differentiated from neoplasms, nodular fasciitis, proliferated myositis, myositis ossificans, and polymyositis. The clinical symptoms, treatments, pathological findings and prognosis of the disease are also discussed. Althouigh its cause is unknown, it is a self-limited disease.
