Abstract:
Intramuscular myxomas are benign soft-tissue tumors that often develop in the thigh. A 66-year-old woman was referred with an abnormal shadow on chest roentgenogram. The tumor was well defined and smooth and originated from the second intercostal space. Positron emission tomography showed no accumulation of 18F-fluorodeoxyglucose in the tumor. The patient attended the outpatient department for follow-up care. Because the mass grew slightly after 52 months, the patient underwent complete removal by video-assisted thoracoscopic surgery. On histopathological examination, the tumor was diagnosed as an intramuscular myxoma in the chest wall. The patient has had no recurrence 3 years after surgery. A case of intramuscular myxoma in the chest wall, completely resected by video-assisted thoracoscopic surgery, is reported. A well-defined, smooth, homogeneous mass in the chest wall may therefore be intramuscular myxoma.
