[Association of small peripheral lung cancer and early stomach cancer].
A combination of peripheral lung oat-cell carcinoma and early gastric highly differentiated adenocarcinoma in a man of 52 with long-term chronic peptic ulcer existing for 20 years is described. Electron microscopic and histochemical examinations of pulmonary carcinoma revealed neurosecretory granules and keratohyalin in the tumor cells. The gastric tumor on the ultrastructural level had cells differentiating in the direction of the glandular and intestinal epithelium. The presence of two independent malignant tumors in the patient was proven by the use of several morphological methods (cytologic, histologic, histochemical and electron microscopic).
