Kaposi’s sarcoma (KS) is a malignancy closely associated with human herpesvirus-8 (HHV-8). KS occurs in immunocompromised subjects—those with HIV infection or after immunosuppressive therapy—but it also occurs without obvious immune deficiency (older men of Mediterranean origin or in central Africans). The incidence of KS in Acquired Immunodeficiency Syndrome (AIDS) has markedly decreased in recent years. Treatment depends on the predisposing condition and the extent of disease. Common management options include no therapy, reversal of immunosuppression, local radiation, and systemic chemotherapy.

Ocular malignancies in the elderly are often difficult to diagnose and manage. The five main cancers found in association with the eye are basal, squamous and sebaceous cell carcinomas, uveal melanoma and malignant cancers to the orbit. These include malignancies from breast, lung, GI, prostate and myelogenous proliferations. This article briefly reviews the most common forms of ocular cancer and brings the general practitioner up to date on the most current data from the Collaborative Ocular Melanoma Study (COMS). We use clinical photos to demonstrate specific clinical signs of cancerous disease. By maintaining a high level of suspicion when treating patients with acute visual symptoms, unnecessary morbidity and mortality may be avoided.
Key words: ophthalmology, cancer, radiotherapy, malignancy.
