Abstract
Mesonephric remnants persist as an appendix of epididymis and paradidymis in efferent ductules in males and skene's glands and Gartner's ducts in females. The mesonephric remnant in the renal parenchyma is extremely rare and only a few cases have been reported in the literature. We present a case with a non-functioning atrophic left kidney. Histopathology showed variable-sized ducts filled with colloid-like material surrounded by collagenized stroma. The ureter showed hypertrophied muscle and a few ducts lined by flattened and a few by columnar epithelium resembling epididymis suggestive of mesonephric remnants. IHC for CD10, PAX 8, and GATA3 was positive. A diagnosis of congenital unilateral hypoplasia of kidneys and ureter with mesonephric remnants was given.
