Anastomosing hemangioma of the kidney
Diagnosis in short

Anastomosing hemangioma of the kidney. H&E stain.

Synonyms renal anastomosing hemangioma

LM vascular tumour with architecture similar to splenic sinsoids, hobnailing, +/-hyaline globules, +/-extramedullary hematopoiesis
LM DDx angiosarcoma, other hemangiomas, other vascular tumours
IHC CD34 +ve, CD31 +ve, HHV-8
Gross brown/mahogany lesion, classically centered on medulla of kidney
Grossing notes total nephrectomy for tumour grossing, partial nephrectomy grossing
Site kidney

Associated Dx +/-end stage renal disease
Prevalence very rare
Prognosis benign
Clin. DDx renal tumours, e.g. renal cell carcinoma

Anastomosing hemangioma of the kidney a rare benign vascular tumour of kidney that may mimic angiosarcoma.[1]

  • Typically seen in end stage renal disease.[3]
  • May mimic renal cell carcinoma clinically.[4]
