Outbreak of Kaposi's sarcoma with cytomegalovirus infection in young homosexual men.
Kaposi's sarcoma, a multicentric malignant neoplasm, occurs in certain geographic areas in the world. It is most common in Equatorial Africa and Eastern Europe. The annual incidence of Kaposi's sarcoma in the United States is between 0.021 and 0.061 per 100,000 persons. The appearance of an outbreak of Kaposi's sarcoma in young homosexual men in New York and California is a new and unique phenomenon. Certain differences are already recognized between the disease in these young men and the ordinary Kaposi's sarcoma. Herein we report our observations of the first 10 cases of Kaposi's sarcoma in young homosexual men. In these patients, the disease follows an aggressive clinical course characterized by widespread skin lesions with early involvement of the lymph nodes. In some of these patients, the result was death in a short period of time after initial diagnosis. In addition, cytomegalovirus infections were seen in these patients, which suggests at least a possible association between this viral and the disease.
