Unusual presentation of a left testicular carcinoid

Testicular carcinoid generally presents either with a palpable (painful or painless) or rarely a nonpalpable mass (when it is diagnosed incidentally on scrotal imaging) of the involved testis. An ipsilateral testicular carcinoid presenting exclusively with contralateral testicular symptoms has never been described in the literature to date. We report a case of nonpalpable left testicular carcinoid diagnosed incidentally on a sonogram done for right testicular pain and swelling, with conspicuous absence of left testicular symptoms. This case highlights the importance of recognizing such an atypical presentation of testicular carcinoid.
