Mediastinal lipoma is a rare intrathoracic tumor which can present as shortness of breath. We describe a morbidly obese patient with progressive dyspnea who got diagnosed endoscopically and is scheduled for surgical resection for a large benign mediastinal lipoma.

We present the case of a 71 y/o man with chronic obstructive pulmonary disease (COPD) who presented with 3 weeks of cough, phlegm, fever, and failed outpatient antibiotic therapy for pneumonia. CT of the chest showed unilateral interstitial changes and bronchoscopic biopsies demonstrated primary lung papillary adenocarcinoma and extensive concentric psammomatous calcifications.

Primary Synovial sarcoma of the lung is an extremely rare entity. Our patient was healthy prior to presentation and came in with a short course of dyspnea and was found to have a large synovial sarcoma on the lung.

We present the case of a twenty two year old Caucasian male with ulcerative colitis on mesalamine who presented with dry cough, fever, malaise and dyspnea on exertion. He had peripheral eosinophilia and apical ground-glass opacities on computed tomography of the chest. He had no new exposures and his infectious workup was non diagnostic. Bronchoalveolar lavage showed eosinophilia raising the suspicion of mesalamine induced eosinophilic pneumonia. His symptoms improved after discontinuing mesalamine with a tapered dose of steroids.
