Malacoplakia of the testis in a renal transplant recipient: case report and review of the literature

Malacoplakia is an uncommon chronic inflammatory disease. The commonest form of malacoplakia after renal transplant is allograft parenchymal involvement while testicular malacoplakia remains one of the rarest forms amongst recipients of renal transplant. We report a case of a 58-year-old gentleman, with live donor renal transplantation 39 years ago, who presented to our unit with one-week history of acute left scrotal pain. Ultrasonography revealed a heterogeneous left testicular mass. Inguinal orchidectomy was done and the lesion was confirmed to be malacoplakia. Testicular malacoplakia is rare. Clinicians managing renal transplant recipients should be alert of this condition in their practice.
