This is from a 30 y/o male who presented with pain in his right groin of few weeks' duration. He was treated with antibiotics by his primary care physician but groin fullness and swelling persisted. Testicular ultrasound showed multiple intratesticular masses consistent with malignancy. CT of chest, abdomen and pelvis done prior to inguinal orchiectomy revealed retroperitoneal lymphadenopathy most consistent with metastases from his testicular cancer. Serum tumor markers showed normal AFP and beta-hCG and elevated LDH.
Right inguinal orchiectomy specimen showed a Mixed Germ Cell Tumor consisting of embryonal carcinoma, seminoma, and teratoma.
