식도에서 발생한 Angiocentric T-Cell Lymphoma

In this study we present a case of an angiocentric T-cell lymphoma (ACTL) which involve the esophagus. A 37-year-old male was admitted with dysphagia, odynophagia, and weight loss for 3 months. Two months before his admission, he had undergone on endoscopy with a biopsy. The first endoscopic findings revealed a large ulcerative lesion on the esophagus, although there had been no evidence of lymphoma upon microscopic examination. On the follow up endoscopic examination, this ulcerative lesion revealed progressive and destructive change. Histopathology of the third biopsied specimens showed large atypical lymphocyte infiltrates with angiocentric and angioinvasive features. Immunohistochemical studies revealed that the atypical (large) lymphocytes had T-cell phenotypes (CD3+, CD5+, and CD43+) and contained few reactive B-cells (CD20+), We assume that this is the first case of ACTL involving the esophagus and larynx.
