Fig. 4From: A renal aplasia case mimicking radiologically as unilateral renal agenesis in a child with spina bifida, atresia ani and unilateral undescended testis: a case reportHistopathology examination. A The blunt-end ureter specimen microscopically showed primitive appearing tubules of renal tissue with dilated-atrophic tubule and colloid-like hyaline cast formation (thyroidization) (40x). B Fibrotic stroma with the chronic inflammatory cells and island of metaplastic cartilage were observed (white arrow) (100x). C The non-sclerotic glomeruli still can be observed (400x). D Urothelial cells lined proximal segment of ureter and infiltrated by chronic inflammatory cells (100x)Back to article page
