Testicular sarcoidosis.
A 20 year old black man presented with shortness of breath, hilar adenopathy, monoarticular arthritis, polydipsia and polyuria, and bilateral testicular masses. Transbronchial biopsy revealed noncaseating granulomas consistent with sarcoidosis. Subsequent work-up demonstrated hypothalamic dysfunction, and joint fluid analysis was consistent with sarcoid arthropathy. Concern over the possibility of a testicular neoplasm led to right testicular biopsy which revealed noncaseating granulomas consistent with testicular sarcoidosis. A short course of steroid therapy resulted in clinical improvement and complete resolution of the remaining left testicular mass.

Necrosis of thyroid nodules after fine needle aspiration.
In a series of 200 fine needle aspirations (FNA) of the thyroid, necrosis around the needle tract was histologically evident in 2 of 30 cases with surgical follow-up. In one case of a differentiated thyroid carcinoma, necrosis with involution of the nodule was the dominant finding. This suggests that FNA can induce necrosis and apparent clinical regression of thyroid neoplasms. We believe, however, that a positive cytologic diagnosis coupled with a clinical suspicion of neoplasm should lead to surgical intervention, despite clinical regression following FNA.
