Abstract:
Mesonephric remnants have been rarely reported in the genitourinary system and sometimes impose a diagnostic challenge both clinically and pathologically. We reported a case of mesonephric remnant hyperplasia with mixed acinar/tubular and epididymis/vas deferens-like morphologies occurring in the renal parenchyma of a unilateral hypoplastic kidney, which has not been previously described.

Anatomical Position and Dimensions
The kidneys are retroperitoneal organs positioned against the posterior abdominal wall on either side of the spine, roughly between the twelfth thoracic and third lumbar vertebrae. Each kidney is typically 10-12 cm long, 5-6 cm wide, and 3-4 cm thick, weighing about 150 grams.

Glomerulus: Structure and Function
The glomerulus is a tiny, intricate network of capillaries located at the beginning of the nephron. It's enveloped by the Bowman's capsule and receives its blood supply from an afferent arteriole, which divides into numerous...
