[Coincidence of testicular germ cell tumor and sarcoidosis: A diagnostic challenge].

Several case reports and small case series have described a total of 66 patients with sarcoidosis and testicular cancer so far. This report describes three additional cases. We highlight the association of sarcoidosis and testicular cancer and comment on the potential impact of this connection on the interpretation of the radiological and pathological findings in suspected cancer relapse. Sarcoidosis, a condition that can be combined with testicular cancer, should always be considered in the differential diagnosis.
