Focal myositis is an inflammatory pseudotumor of skeletal muscle that may involve the head and neck. It can closely mimic either a neoplastic or infectious process. We present the case of a 7-year-old boy with a 2-week history of a painful, unilateral neck swelling, fever, and torticollis. He failed to respond to antibiotic therapy and required an open neck exploration. An incisional biopsy of the indurated, inflammatory tissue adherent to his sternocleidomastoid muscle showed focal myositis. Focal myositis is an unusual, but important possibility in the differential diagnosis of any neck mass and especially one in a child. Although its cause is unknown, it is a self-limited disease and neither excisional biopsy nor radical resection is justified.
局灶性肌炎是一种可累及头颈部的骨骼肌炎性假瘤。它可酷似肿瘤性或感染性病变。我们报告一例7岁男孩，有2周的单侧颈部疼痛性肿胀、发热和斜颈病史。他对抗生素治疗无效，需要进行颈部开放性探查。对附着于胸锁乳突肌的硬结性炎性组织进行切开活检，显示为局灶性肌炎。局灶性肌炎在任何颈部肿块的鉴别诊断中，尤其是儿童颈部肿块，是一种不常见但重要的可能情况。虽然其病因不明，但它是一种自限性疾病，切除活检或根治性切除均不合理。
