Value of Immunohistochemical Staining in a Patient with Multiple Primary Tumors

Abstract

A patient with a history of carcinoma of the breast, carcinoma of the lung and a posunastectomy angiosarcoma in lymphedema (Stewart-Treves syndrome) developed additional tumor masses in the arm. Immunocytochemical staining with a panel of antibodies showed them to be unrelated to any of the earlier neoplasms. The fourth tumor was shown to be malignant melanoma.
