A Rare Coexistence of Seminoma and Hodgkin's Lymphoma in Hawai'i.

Both Hodgkin's lymphoma and testicular cancers can present in young men; however, concurrent Hodgkin's lymphoma with seminoma is very rare. When they do coexist, careful consideration must be made to avoid missing new cancer by assuming the presence of primary metastatic disease when lymphadenopathy presents. Here we present a rare case of coexistence of seminoma and Hodgkin's lymphoma and the staging and treatment challenges associated with a 2-cancer diagnosis.
