Primary highly differentiated breast angiosarcoma in an adolescent girl

Primary angiosarcoma of the breast is very rare. Surgery is the principal mode of treatment for primary angiosarcoma of the breast and generally consists of a total mastectomy. To discuss its etiology and treatment principles, we reported a case of primary mammary angiosarcoma in an adolescent girl. The patient had been treated in other hospitals several times due to erythema of the breast as inflammatory treatment was considered, until pathological nature was determined after we performed pathological needle puncture. The case discussed here is unique in its own way, having clinical imaging and pathological features of primary angiosarcoma in an adolescent girl and it is known that primary angiosarcoma is unusual for this age group.
