An endobronchial lipoma mimicking asthma and malignancy.

Endobronchial lipomas are rare benign tumours of the lung. Bronchial occlusion may lead to a misdiagnosis of asthma or malignancy. We describe a 52-year-old man treated for asthma for several years, who presented with non-resolving right upper lobe pneumonia. Bronchoscopy proved to be diagnostic and therapeutic. Clinical characteristics of this unique entity are discussed.

An incidental right atrial mass: cavernous hemangioma.

Cardiac hemangiomas are rare benign tumors of the heart typically diagnosed incidentally. We report a case of a 70-year-old man with a right atrial cavernous hemangioma and a concomitant pulmonary embolism. The possible association, clinical features, operative procedure, and pathologic findings are described.
