Aggressive conjunctival Kaposi sarcoma as the initial manifestation of acquired immunodeficiency syndrome

PURPOSE: To report a case of Kaposi sarcoma in a patient with previously undiagnosed Human Immunodeficiency Virus (HIV) infection. OBSERVATIONS: A 23-year-old male patient presented to the eye clinic with complaints of redness of his left eye for the past month. The patient had been seen one day prior to presentation in the emergency department for a neck mass and pneumonia. Exam was notable for a left hemorrhagic, nodular, bulbar conjunctival mass, a right hemorrhagic conjunctival lesion, and violaceous facial skin lesions. Due to suspicion for conjunctival Kaposi sarcoma, HIV and Acquired Immune Deficiency Syndrome (AIDS) serologies were obtained which returned positive. Biopsies of the ocular mass and axillary lymph nodes confirmed Kaposi sarcoma. The patient was started on anti-retroviral therapy and Doxorubicin. The left conjunctival mass initially progressed to cover most of his cornea but eventually regressed by 6 months. CONCLUSIONS AND IMPORTANCE: Ocular involvement of Kaposi sarcoma as the initial manifestation of HIV/AIDS is rare with only a few reported cases. Since the advent of highly active antiretroviral therapy, conjunctival or adnexal Kaposi sarcoma is not commonly encountered by healthcare providers. Concern for Kaposi sarcoma of the conjunctiva in this patient led to the evaluation for HIV/AIDS. It is vital for all healthcare providers to have Kaposi sarcoma in the differential diagnosis of a hemorrhagic conjunctival or adnexal mass and be familiar with its association with HIV/AIDS. If suspected, appropriate counseling and testing should be performed.
