Capillary hemangioblastoma of soft tissue: report of a case and review of the literature.

Capillary hemangioblastoma (CH) is a tumor of unknown histogenesis that arises primarily in the posterior cranial fossa, either as a sporadic event or in association with von Hippel-Lindau disease. To date, only 6 examples of a tumor with morphological features of CH arising in the somatic soft tissues have been documented in case reports and small series, and 3 of these tumors were associated with a peripheral nerve. Herein, we report a case of CH arising in the gastrocnemius muscle and not associated with a peripheral nerve in a 53-year-old woman with no clinical stigmata or family history of von Hippel-Lindau disease.
