Overview
Differentiating Seminoma from other Diseases
The most common presentation of testicular seminoma is a painless testicular mass.[1] The main differential for testicular mass in young adults is non-seminomatous germ cell tumor (NGCT) which usually appear more heterogenous, often with cysts and calcification.[2] Lymphadenopathy of non-seminomatous germ cell tumor may enhance more heterogenously. Testicular lymphoma is the main differential diagnosis to consider when para-aortic lymphadenopathy is the presenting finding or in the setting of bilateral testicular lesions.[2]
Testicular seminoma must be differentiated from:[3][4]
