This is a case report. Literature search was primarily done using PubMed.


A 33-year-old Filipino male presented with a 5-month history of progressive proptosis of the left eye associated with blurring of vision, diplopia, and discomfort in eye movement. Magnetic resonance imaging showed an abnormally-enhancing intraconal mass in the left retro-orbital area with mass effects. Excision biopsy revealed a low-grade vasoformative neoplasm with positive immunostaining for CD34 that is consistent with Kaposi sarcoma. Serologic test for HIV turned out positive. Two months after surgery, intracranial enhancing lesions were detected after bouts of seizures and severe headaches. The patient was lost to follow-up before highly active antiretroviral therapy (HAART) could be initiated.


HIV-associated Kaposi sarcoma can occur in unusual locations including the orbit and should be considered in young, high-risk individuals presenting with ocular complaints.
