Sarcoidosis With Bilateral Testicular Involvement Resembling Testicular Cancer: A Rare Case Report.

Sarcoidosis is a granulomatous inflammatory disease that could potentially involve multiple organ systems. It causes noncaseating granulomas in tissues, and at least two organs must be involved to make a diagnosis. In sarcoidosis patients, if there is a mass in the testicles, a testicular biopsy should be performed to exclude malignancies because of infrequent testicular involvement. We present a 23-year-old male diagnosed with sarcoidosis who had a bilateral testicular mass. A testicular biopsy was performed because of bilateral involvement. The biopsy revealed a diagnosis of sarcoidosis. After high-dose steroid treatment, the lesions regressed. This paper presents a sarcoidosis case with testicular involvement that imitates testicular tumors. Testicular tumors and testicular involvement of sarcoidosis are two different pathologies that may mimic each other, confuse clinicians, and/or lead to misdiagnosis and mistreatment.
