A case of sarcoidosis following chemotherapy for follicular lymphoma

A 53-year-old man, who had received salvage chemotherapy for follicular lymphoma, complained of fever and dry cough. High-resolution computed tomography of the chest showed bilateral diffuse ground-glass opacities with weak F18-fluorodeoxyglucose uptake on positron emission tomography. Transbronchial lung biopsy specimens revealed noncaseating epithelioid cell granulomas. His serum angiotensin-converting enzyme (ACE) level was elevated and ophthalmologic examination showed uveitis. Sarcoidosis was diagnosed, he was treated with corticosteroid eye drops, and his chest ground-glass opacities spontaneously resolved after 2 months. Here, we report a rare case of sarcoidosis with a review of the literature.
