A 22-year-old man was admitted with the chief complaint of left flank colicky pain. Physical examination revealed huge abdominal mass and absence of left intrascrotal contents. Right hydrothorax and left ureteral calculi were pointed out with radiography. The abdominal tumor was reduced by effective chemotherapy. Extirpation confirmed the presence of seminoma and persistent Mullerian duct structure. This case showed left testicular transverse ectopia. In our review of the Japanese literature, 16 cases of transverse testicular ectopia accompanied with testicular tumor are reported.
