Abstract
We report a case of transverse testicular ectopia (TTE) with complete descent to the contralateral scrotum. A fifty-five-year-old man with malignant lymphoma in the left inguinal region was diagnosed with TTE and persistent Müllerian duct syndrome (PMDS) via CT scan. Ultrasound imaging and palpation revealed no malignant findings in the testes. Given the rarity of malignant transformation in müllerian duct remnant, we opted for follow-up through palpation and ultrasound. TTE is typically diagnosed in childhood, making adult cases comparatively rare. This case is particularly notable due to the complete descent of the testes. We also collected data on Japanese adult cases of TTE since 1980. Herein, we present this case of TTE along with a review of the literature.
