Clinicopathological study of vascular tumors of the breast: a series of ten patients with a long follow-up.

Ten cases of vascular tumors of the breast were examined in our laboratory during the last decade (1992-2001). Nine patients were female and one male (ages 31-77, average 52 years). Six patients presented parenchymal vascular lesions (1 angiosarcoma, 1 atypical hemangioma, 3 perilobular hemangiomas, 1 cavernous hemangioma) measuring 0.5-6 cm in the greatest diameter. Two lesions were accidental findings in lumpectomy specimens excised for fibrocystic disease with microcalcifications. Four patients presented non-parenchymal vascular lesions: three cavermous hemangiomas (one in a male patient) and one angiolipoma measuring 1-6 cm in diameter. All tumors were treated by lumpectomy with the exception of the atypical hemangioma which was treated by simple mastectomy. The patient with the angiosarcoma was treated by simple mastectomy, radiotherapy and chemotherapy and died with disseminated disease three years after initial diagnosis. All other patients are well up to date (follow-up 1-9 years).
