| Diagnosis in short |
Anastomosing hemangioma a rare benign vascular tumour that is typically found in the kidney and may mimic angiosarcoma.[1]
General
- Rare - case reports.
- Typically seen in end stage renal disease.[2]
Gross
Features:
- Mahogany/brown - centered on medulla of kidney.[2]
Microscopic
Features:
- Vascular tumour characterized by vessels that fuse/join (anastomose) - also described as splenic sinusoids-like.[2]
- +/-Hobnail morphology.
- +/-Cytoplasmic hyaline globules.
- +/-Extramedullary hematopoiesis.
- Nucleated red blood cells.
- Megakaryocytes.
Note:
- Tumour may extend into surrounding adipose tissue.
DDx:
- Angiosarcoma - nuclear atypia, more proliferative activity.
IHC
Features:[2]
- CD31 +ve.
- CD34 +ve.
- HHV8 -ve.
