Hemangioblastoma in the Lung: Metastatic or Primary Lesions?

الملخص EN

Hemangioblastoma primarily occurs in the CNS, most commonly in the posterior fossa.

Extracranial locations are less common, and metastatic tumor involving the lung is exceedingly rare with only three cases previously reported.

Two were autopsy studies in patients who died of complications of the CNS hemangioblastomas in 1943 and 1981, and the third was mentioned in a case report addendum providing follow-up information on hepatic hemangioblastoma in 1991.

We report a case of a 48-year-old man who presented with multiple lung nodules treated by surgical excision.

Pathological study revealed features classic for hemangioblastoma.

The patient had a remote history of hemangioblastomas having been excised from the posterior fossa 7 and 20 years previously.

This report details a fourth case of metastatic pulmonary hemangioblastoma.

It is the first report on surgically resected hemangioblastomas from the lung of a living patient with histological and immunohistochemical characterization.
