renal congenital capillary proliferation

Renal vascular lesions (RVL) are rare and their morphological spectrum remains largely unknown, particularly in children.

Congenital capillary proliferation of the kidney (CCPK) may represent a malformation or neoplastic proliferation.

It shows overlapping features with congenital hemangioma of the liver (solitary congenital hepatic hemangioma - SCHH) and congenital nonprogressive hemangioma (CNH) of the skin and soft tissue, suggesting a possible common pathogenesis among these three entities.
