급성백혈병과 식도암이 병발한 1례

Abstract

Although there are many cases of acute leukemia as a secondary malignancy that is a rare late complication of chemotherapy or radiotherapy, the coexistence of esophageal cancer and acute leukemia is not reported. Recently, we experienced a case of acute leukemia associated with esophageal cancer. A 77-year-old man presented with dysphagia. Esophagoscopy revealed infiltration mass at upper one-third of the esophagus. Examination confirmed squamous cell carcinoma. Peripheral blood examination revealed leukocytosis, anemia and thrombocytopenia. Bone marrow examination showed 61% blasts and 17.5% atypical cells. These cells showed positivity of CD5, CD7, CD13, CD33, CD34 and HLA-DR on immunophenotyping study.
