AIDS-Related Kaposi Sarcoma Associated with Steroid-Unresponsive Periorbital Lymphedema that Responded to Chemotherapy

Abstract

Background: As an AIDS-defining illness, the neoplasm Kaposi sarcoma (KS) classically presents as cutaneous lesions that are often associated with periorbital edema. This association with KS is important because it frequently leads to the misuse of steroids in HIV-infected patients. This report presents 2 cases of AIDS-related Kaposi sarcoma (AIDS-KS) associated with severe steroid-unresponsive periorbital lymphedema that responded to chemotherapy. Case Reports: Case 1: A 30-year-old African-American man with KS-related periorbital edema suffered progression after receiving multiple corticosteroids for a presumed hypersensitivity reaction. After multiple hospitalizations, the patient’s KS had disseminated, and he eventually opted for hospice. Case 2: A 29-year-old White male with recurrent facial edema had been repeatedly treated with corticosteroids for impending anaphylaxis reactions. He had multiple admissions with similar presentations, and it was found that his KS had progressed. After receiving chemotherapy, his facial edema has not recurred. Conclusions: The failure to recognize periorbital edema as tumor-associated edema has direct consequences for the management of AIDS-KS. In addition to a delay in administering chemotherapy, the mischaracterization of perior-bital edema as a hypersensitivity/allergic reaction often prompts the use of corticosteroids, potentially exacer-bating the underlying AIDS-KS. Despite the current evidence, clinicians continue to order steroids in advanced AIDS-KS patients presenting with periorbital edema. Although that management is started with the best in-tentions and done with concerns for airway compromise, this anchoring bias could lead to devastating consequences and a rather poor prognosis.
