Esophageal carcinosarcoma is an extremely rare tumor, and surgery is the mainstay of treatment. We report two patients with carcinosarcoma of the esophagus who received neoadjuvant chemoradiotherapy and underwent curative resection. Patient 1 was a 50-year-old man with a type 2 lesion in the upper thoracic esophagus; clinical stage was T3 or partial T4N1M0. After chemoradiotherapy the tumor and the...
We reviewed the clinicopathological characteristics of 14 patients who underwent resection of basaloid squamous carcinoma (BSC) of the esophagus. The mean age was 65.3 years, and all patients were male. Seven patients had superficial BSCs and 7 had advanced BSCs. BSCs were associated with high rates of lymph node metastases and venous invasion. With regard to immunohistochemistry, the rate of cyclin...
We report a patient with synchronous gastrointestinal stromal tumors (GISTs) of the stomach and esophagus. The gastric GIST was larger than that in the esophagus, and no direct connection between the two lesions was seen microscopically. Based on molecular analysis, both lesions had the same c-kit mutation on exon 11, with deletion of codon 557–558. Analysis of normal gastric tissue showed no mutations...
The patient was a 75-year-old man. Under a diagnosis of angina pectoris, he was being treated with aspirin and ticlopidine hydrochloride at a local clinic. Severe postprandial pharyngeal/thoracic pain and hematemesis occurred. Upper digestive tract endoscopy revealed an extensive submucosal hematoma involving the esophageal orifice and cardia. Computed tomography (CT) scan did not show aortic dissociation...
