摘要

Myxoma, a New Latin word derived from the Greek word ＂muxa,＂ which mean mucus, is a myxoid tumor of the primitive connective tissue that commonly arises in the heart. Intramuscular myxomas are rare, benign, soft-tissue tumors arising from skeletal muscles. Such tumors usually manifest as slow-growing masses of the skeletal muscle, primarily affecting individuals aged 40-60 years, predominantly women. Clinically, the tumor presents as a painless, palpable mass with symptoms that are dependent of its size or location in the body. Symptoms, if any, are usually vague. The only widely available diagnostic tests are imaging techniques, such as ultrasonography, computed tomography, and magnetic resonance imaging. Although imaging techniques are helpful, the final diagnosis can be made only following histological examination after excision.

肌內黏液瘤是間充質來源的一種罕見的良性腫瘤病變，從肌肉長出，最常見位於大肌肉大腿、肩部、臀部或上臂。腫瘤表現為一個堅定、無痛、緩慢增大的腫塊，稍有移動，有時波動。當腫瘤長大至一定程度，依腫瘤大小會形成不同症狀。好發於40～60歲成人女性居多。病因是未知的，但創傷的先前歷史經常報導。臨床診斷需靠超音波、CT掃描和MRI已在病變的鑑別診斷中使用。最終診斷仍需手術腫瘤切除之病理報告。
