FAMILIAL ADENOMATOUS POLYPOSIS AND LUNG-CANCER

A 43-year-old man presented with a lung nodule 19 years after undergoing a total colectomy for familial adenomatous polyposis (FAP). There had been no evidence of malignant transformation in the colectomy specimen, and current gastrointestinal investigation did not reveal evidence of tumor. Pathological analysis of the lung nodule demonstrated adenocarcinoma of the lung of the fetal type. This is the first reported case of a lung neoplasm in a patient with FAP. The development of an unusual lung tumor in a patient with FAP, a condition associated with other extracolonic tumors, suggests that there may be an association between the two conditions.
