Malignant neoplasms known to develop after external beam radiation include angiosarcoma. Although angiosarcoma developing in a lymphedematous arm after radical mastectomy is a well-known phenomenon, cutaneous angiosarcoma after radiotherapy for breast carcinoma has been rarely documented. Herein we present a case with cutaneous angiosarcoma that developed in a 69-year-old woman's breast 5 years after she underwent conservative treatment to the breast: lumpectomy, axillary lymph node dissection, and radiation therapy to the breast. The possible relation of the angiosarcoma to the initial radiotherapy, early diagnosis, and treatment is discussed.

Primary adrenal lymphoma is extremely rare. Only 75 cases have been reported in the medical literature. A case of non-Hodgkin's lymphoma originating in both adrenal glands is presented. Combination chemotherapy apparently produced complete disappearance of the primary lymphomatous lesions, but subsequently a cerebral relapse was discovered 6 months later, in the form of a solid brain mass. Cranial extension of primary adrenal lymphoma is extremely unusual, and the presentation as a solid mass seems to be unique.

Angiosarcoma is a rare malignant tumor arising from endothelial cells of blood vessels or lymphatic channels. Therapeutic irradiation, thoriumdioxide administration, pyothorax, and polyvinyl chloride exposure have been shown to be predisposing factors for developing angiosarcoma. Accidental radiation exposure has not been associated with angiosarcoma. We present an unusual case of angiosarcoma of the spleen, with metastases to bone, liver, breast, and bone marrow, in a woman who lived near the Chernobyl nuclear facility in the former Soviet Union at the time of the reactor accident in 1986. To the best of our knowledge, this is the first report of metastatic angiosarcoma after accidental radiation exposure.
