[A case of skeletal muscle metastasis on the left thigh after esophagectomy for esophageal adenocarcinoma in Barrett' s esophagus].

Abstract We report the case of a 45-year-old man with advanced esophageal adenocarcinoma in Barrett's esophagus. After neoadjuvant chemotherapy using S-1, docetaxel, and cisplatin, the patient underwent thoracoscopic esophagectomy with a two-field lymph node dissection and reconstruction with a gastric tube through the posterior mediastinal route. The pathological stage was CT-pT4 (diaphragm), ly2, v1, CT-pN1, CT-pStage IVa. Fourteen months after the operation, the patient complained of pain in his left thigh with a palpable indurated mass that was increasing in size. Needle biopsy specimens revealed skeletal muscle metastasis of the adenocarcinoma. The metastastic lesion was resected and local control was achieved successfully for 13 months, after which the patient died because of intrabronchial bleeding.
