Cardiac tamponade as the initial presentation of bronchioloalveolar cell carcinoma

Bronchioloalveolar cell carcinoma (BCC) is a relatively uncommon form of bronchogenic cancer with an insidious onset and a variety of radiographic appearances. Although the World Health Organization currently classifies it as a subtype of adenocarcinoma, many investigators view BCC as a distinct tumor with characteristic clinical features. There are still uncertainties regarding its origin, as well as the significance of associated clinical findings such as cardiac tamponade.
