Case report
angiosarcoma of the right breast. The breast tumor had been initially noted as a mass about 30 mm in diameter 3 years before, and was excised with the overlying skin. The histopathology initially provided a diagnosis of capillary hemangioma. A local relapse was found 7 months after surgery, and the mass was again excised. The histopathology again confirmed the diagnosis of capillary hemangioma. Another local recurrence occurred 18 months after the first presentation, and an incisional biopsy then yielded a diagnosis of angiosarcoma. The patient was treated with 30 Gy of 6°Co irradiation for 3 months. Because of another local recurrence, a mastectomy of the breast was then performed. The maxillary right second and third molars were extracted to eliminate traumatic irritation (Fig. 1), and a second biopsy of the lesion confirmed the diagnosis of capillary hemangioma. The mass, however, was gradually growing in size during follow-up examinations, and a third biopsy was taken. This time the histopathologic features were consistent with the primary lesion of the breast,
T h e c o m m o n sites for metastasis o f b r e a s t a n g i o s a r c o m a are, in order o f frequency, lung, skin a n d s u b c u t a n e o u s tissue, bone, liver, brain, a n d o v a r y 2. T h e metastatic lesions are m a i n l y due to h e m a t o g e n o u s spread. A review of the literature yielded only three cases
A 59-year-old woman was referred to the Department of OMF Surgery, Nagoya City University Hospital, for assessment of a lump on the maxillary right molar gingiva. The patient had been aware of the tumor for 2 weeks. At the initial visit, an irregular, purple mass, approximately 20 mm in diameter, was found in the maxillary right first molar region. The mass was soft and slightly tender on palpation. A metal bridge was fixed between the maxillary right first premolar and second molar. A poorly demarcated radiolucency in the alveolar bone was noted on radiographic examination. The bridge was removed, and an incisional biopsy was performed at the buccal side of the lesion. The histopathology yielded a diagnosis of capillary hemangioma of the gingiva. The past medical history revealed an

A n g i o s a r c o m a is rare b o t h as p r i m a r y a n d as metastatic t u m o r in the oral cavity 4'5'6. A review of the literature revealed only three r e p o r t e d cases o f a n g i o s a r c o m a m e t a s t a t i c to the oral cavity 3'4'6. A n g i o s a r c o m a of the b r e a s t is also relatively rare, constituting app r o x i m a t e l y 3 9% o f all b r e a s t sarc o m a s 1'2. It often requires multiple biopsies before the diagnosis can be established because o f the t u m o r ' s resemblance in b o t h clinical a n d microscopic a p p e a r a n c e with other, b e n i g n lesions 2'8. There is also considerable v a r i a t i o n in b o t h b e h a v i o r a n d microscopic appearance in different a n a t o m i c locations. This p a p e r describes a case o f breast a n g i o s a r c o m a m e t a s t a t i c to the gingiva w i t h o u t dissemination.
and the diagnosis was subsequently established as a metastatic angiosarcoma (Fig. 2). Severe bleeding had been caused by traumatic occlusion, and for this reason, and also because of the seemingly well-controlled primary lesion and the fact that no obvious metastatic deposits in the other regions were present, a subtotal maxillectomy was undertaken by a Weber-Fergusson incision. The postoperative condition was uneventful for 1 month after the surgery. An acute cardiovascular failure then occurred, and the patient died because of it 2 d later. An autopsy was not performed.
Discussion
Breast angiosarcoma metastatic to gingiva of angiosarcoma metastatic to the oral cavity 3,4,6, and only one case o f metastatic angiosarcoma from the breast with multiple gingival involvement 4. Angiosarcoma metastatic to the maxillary gingiva is thus extremely rare. In the present case, the metastatic site was initially thought to be caused by an inflammation related to the poorly fitting bridge. Inflammatory lesions often cause misdiagnosis in the initial stage, as was also noted in previous cases o f gingival metastases f r o m angiosarcoma of distant origins 4'6. Angiosarcoma is often mistaken for hemangioma 2'7's or reactive inflammatory process 6. The false negative result in the histologic diagnosis may be attributable to a superficial biopsy which did not represent the tumor 7. Angiosarc o m a has a pleomorphic appearance with few mitotic figures. A relatively bland appearance of breast angiosarc o m a is usually maintained in the metastatic deposit 5. The appearance of recurrences and metastases is usually similar to that of the original neoplasm. There is, however, a tendency for recurrences and metastases to contain more solid tumor or to exhibit increased pleomorphism in a few instances 5. These
conditions may lead to misdiagnosis, as in the patient described. There is considerable variation in behavior when angiosarcomas occur at different anatomic sites. Therapeutic results for angiosarcoma in the oral cavity are more encouraging than those in other sites s, whereas breast angiosarcoma has the worst prognosis 2,5. M o s t patients with breast angiosarcoma die as a result of dissemination 2. Simple excision of the lesion as performed initially in many cases is invariably followed by local recurrence 2. The t u m o r appears radioresistant and responds poorly to chemotherapy j. Therefore, resection is the treatment of choice for the metastatic t u m o r when the primary lesion is under control. The case described emphasizes the need to maintain a high level of vigilance when inflammatory oral lesions are seen in patients with a history of breast angiosarcoma.
