Sarcoidosis of the humerus is exceptionally rare and only a few cases have been reported. In this minireview, a case of enchondroma in proximal humerus mimicking sarcoidosis and the features of bone involvement of sarcoidosis were reviewed. A 41-year-old female who was diagnosed with sarcoidosis in 2009 had used corticosteroids for 4 months. She had not any symptoms until 2014. She was admitted the clinic with a 2-month-history of erythema nodosum on her legs and right shoulder pain. Values of laboratory tests were all within normal limits except erythrocyte sedimentation rate and C-reactive protein levels. The mass in the proximal metaphyseal humerus has the characteristic as a medullary lesion which had calcifications in CT sections. MR images that the mass had low signal intensity on T1-weighted images and heterogeneous high signal intensity on T2-weighted images. It had irregular nodular contrast and the mass did not cause the expansion of the bone. Increased activity was observed on scintigraphy. We suspected the mass which was realized incidentally in a patient with sarcoidosis, could be bone sarcoidosis. As a result of our biopsy, it was enchondroma. Bone neoplasms should be kept in mind in issues like our case report.
