Hemangiopericytoma of the adult male breast.

Author information

Department of Pathology, 150th Hospital of People's Liberation Army, Luoyang, China.


Hemangiopericytoma (HPC) is a rare tumor originated from the vascular pericytes, and it is uncommon in the breast. Only 2 cases of HPC in the male breast have been reported in the literature. This report presents a case of a 24-year-old man with a mass in his right breast. Under local anesthesia, the tumor was excised and diagnosed as `malignant tumor of the breast, perhaps originated from the vessel tissues` based on pathological examination. Finally, a modified radical mastectomy and an axilla fossa sampling were performed, and 4 lymph nodes showed symptoms of reactive hyperplasia. We followed the patient without any treatment and no local recurrence or metastasis has been observed. We also review the literature and discuss the characteristics, immuno-phenotype, and prognosis of HPC. The accurate diagnosis of HPC depends on the appropriate histological and immunohistochemical examination.
