Abstract
-
Renal dysplasia results from aberrant metanephric histogenesis caused fundamentally by a
defect in inducer tissue or responding tissue. Dysplastic kidneys vary tremendously in gross and
microscopic appearance but are characterized by abnormal organization and a mixed population of
primitive structures, such as fetal or immature cartilage, dysplastic ducts, immature tubules, and
undifferentiated mesenchyme. We report a case of unilateral multicystic renal dysplasia associated
with an ipsilateral ectopic ureteral orifice entering a seminal vesicle cyst in a 33-year-old man. He
was admitted due to primary infertility which had developed three years ago. The his semen
analysis revealed oligospermia. No evidence of a family history of renal dysplasia was reported.
Microscopic examination showed that the entire kidney was composed of cysts lined by flattened
cells, dysplastic ducts and immature tubules surrounded by collars of spindle cells, primitive
mesenchyme, and a few aberrantly formed glomeruli.
