Our present histological knowledge of the port-wine stain is limited because of the small size of biopsies taken in the past. During the last two decades, Clodius has performed subtotal excision of port-wine stains, and has covered the defects with full thickness skin grafts. The availability of large surgical specimens of dermis affected by port-wine stain prompted the present study The primary diagnosis is made with a computed tomography scan (CT scan). On a scan, hemangioblastoma shows as a well-defined, low attenuation region in the posterior fossa with an enhancing nodule on the wall. Sometimes multiple lesions are present.. Treatment. The treatment for hemangioblastoma is surgical excision of the tumor. Although usually straightforward to carry out, recurrence of the.
