Abstract
We report an unusual case of bronchioloalveolar carcinoma characterized by production of a large quantity of sputum accompanied by drastic electrolyte and fluid loss. The sputum contained a high level of gastrointestinal cancer-associated antigen (CA19-9) and carcinoembryonic antigen (CEA). An immunohistochemical study of tumor cells showed the specific distribution of gastrointestinal cancer-associated antigen and carcinoembryonic stains, which were localized in the apical region of tumor cells.
