“…Other patients receiving immunosuppressive drugs, including a patient with systematic lupus erythematosus (Klein et al, 1974) and a patient with myasthenia gravis (Ulbright and Santa Cruz, 1981), have developed Kaposi's sarcoma. It has also been described in a number of other disorders of the immune system, including immunodeficiencies, paraproteinemias, polymositis, and pemphigus (Dantzig, 1974;Law, 1974;Safai, 1984;Ulbright and Santa Cruz, 1981). Second malignancies are very commonly associated with Kaposi's sarcoma, occurring in 19 to 37% of cases of classical Kaposi's sarcoma (DiGiovanna and Safai, 1981;Reynolds et al, 1965;Safai et al, 1980).…”
