Successful Treatment of an Atypical Presentation of Disseminated Retroperitoneal Seminoma: A Case Report

Retroperitoneal masses range from primary neoplasms to solid organ neoplasms to metastatic disease. The challenge with these masses is accurate and prompt diagnosis. Treatment varies for each retroperitoneal mass. A painless lump in the testicle is the most common sign of testicular cancer. Symptoms related to the site of the metastases (ie, back/flank pain) can sometimes occur, making early diagnosis exceedingly challenging. Radical orchiectomy is the mainstay of treatment for seminomatous testicular tumors. Management following surgery is dependent upon staging. Surveillance following treatment requires frequent office visits as well as abdomen/pelvis CT scans and/or serum tumor markers.
