Abstract

Since the entity of postmastectomy lymphangiosarcoma was first reported by Stewart and Treves in 1948, postmastectomy lymphangiosarcoma has become a well recognized, uncommon malignant tumor which occurs in the upper extremity following mastectomy for mammary carcinoma. The postmastectomy lymphangiosarcoma occurred at an average age of 63.9 years and at an average of 10 years and 3 months following mastectomy. The lymphangiosarcoma raised from blood and lymphatic vessel. The histologic appearance has been observed edematous dermiss and dilated lymphatics lining with malignant cells. Most authors recommend radical amputation for treatment, either shoulder disarticulation or forequarter amputation. Other modalities of treatment including radiotherapy were considered as ineffetive. The present report provides a case of the regression of postmastectomy lymphangiosarcoma with chronic lymphedema by external irradiation. Radiation therapy was used as primary therapy. Total tumor dose of 6500 cGy in 9 wks was delivered using 6 MV x-ray and 8 MeV electron.

유방절제술 후 임파육종은 유방암 환자에서 유방절제술 후 상지에 생기는 흔치 않은 악성 암이다. 유방절제술 후 임파육종에 평균 발병 연령은 63.9세이고 유방절제 후 발병할 때까지의 기간은 평균 10년 3개월이다. 유방절제술 후 임파육종은 혈관과 임파관에서부터 발생하는 것으로 알려져 있고 조직학적 소견은 진피의 부종과 악성세포로 둘러싸인 확장된 임파선이 특징이다. 견관절 분리술이나 전사분부 절제술 등의 광범위한 절제가 가장 효과적인 치료법으로 알려져 있고 방사선 치료를 포함한 다른 치료방법은 큰 도움이 않되는 것으로 보고되고 있다. 저자들은 유방절제술 후 만성 림프부종을 동반한 임파육종이 외부 방사선 조사에 의하여 종괴의 감소를 보여 이에 보고하는 바이다.
