Abstract
This case report presents a rare occurrence of 2 primary tumors in the same patient: a transitional cell carcinoma of the bladder and an atypical carcinoid of the lung. The time interval between a linear density and tumor growth to 3 cm, determined by chest radiographs, was 9 mo. The rapidly growing pulmonary nodule was suspected to be a metastasis from the primary transitional cell carcinoma. Fine-needle aspiration revealed malignant cells. Lobectomy, light microscopy, and EM revealed an atypical carcinoid. The definition of atypical requires revision to indicate this tumor''s true potential.
