Abstract
We report a recent case of angiosarcoma of the breast without a history of receiving irradiation therapy. A 19-year-old woman was seen at the hospital because she noticed a lump in the area A of right breast with pain in January 1998. A smoothly and elastic soft tumor was palpable. Ultrasonography showed a 1.32×0.68cm mass with low echogenicity. She underwent an incisional biopsy of the breast. It revealed that the tumor was a cyst and perforated when it was incised. The content of the cyst consisted of serous brown liquid. The resected specimen 5mm in diameter was diagnosed as angiosarcoma. Partial resection of the mammary gland without axillary lymph node dissection was performed. The patient is living and well, and has been free from recurrence as of 2 years and 6 months after the operation. Our case is the 8th report on angiosarcoma of the breast under the size of 3cm in the Japanese literature. Some bibliographycal comments are also presented.
