title: An aggressive non-small cell lung cancer in nonsmokers: A case report of an unusual presentation of micropapillary lung adenocarcinoma.
abstract: We describe a case of an unusual fast growing lung micropapillary-predominant adenocarcinoma in a nonsmoker male patient without pre-existing lung disease. Adenocarcinomas have been described to be slow growing tumors, however our patient presented a fast-growing rate over a period of 21 days. When the patient failed broad spectrum antibiotic coverage, malignancy became part of the differential diagnosis. Once malignancy was detected, prompt identification and treatment was started in order to improve prognosis of the patients.
