hemangioblastoma

 [he-man″je-o-blas-to´mah]
a benign blood vessel tumor of the cerebellum, spinal cord, or retina, consisting of proliferated blood vessel cells and angioblasts. Those arising in the cerebellum (cerebellar hemangioblastoma) may be cystic and associated with von hippel-lindau disease. Called also angioblastoma.
cerebellar hemangioblastoma hemangioblastoma of the cerebellum, often cystic; an autosomal dominant form is associated with von Hippel-Lindau disease.

Hemangioblastoma

(1) A tumour of soft tissues, which is of intermediate aggressiveness and thus preferably known as hemangioendothelioma.
(2) A vascularised cerebellar tumour, representing 2% of CNS neoplasms, which occurs in the 3rd–4th decades, either alone or associated with von-Hippel-Lindau syndrome, phaeochromocytoma, syringomyelia or erythrocythemia.

VHL Type 1 is characterized by tumor structures such as central nervous system or retinal hemangioblastoma, but no pheochromocytoma.
Metastatic clear cell renal cell carcinoma (CCRCC) can bear a striking similarity to hemangioblastoma. CCRCC is usually positive for PAX8 and CAIX and negative for S100 and inhibin-A.
For the central nervous system (CNS), it has been reported that screening hemangioblastomas in asymptomatic individuals was not indicated since surgery was considered only in symptomatic subjects.
The main diagnostic considerations are hemangioblastoma (particularly in the absence of homogenous enhancement), metastatic disease, ependymoma, or a choroid plexus tumor.
Indeed, the expression of this protein has been also documented in hemangioblastoma (HBL) [6, 7, 13, 14], a slow growing vascular tumour, which origins from mesoderm derived, embryologically arrested hemangioblasts [4, 13], which also express this protein [15].
