Ocular involvement in an HIV-infected patient: not always an infectious disease. An interesting case without apparent cause

We describe the case of a young girl with HIV infection vertically transmitted who presented a long-lasting ocular involvement characterized by several relapses and remissions. Good viral and immunological status made infective or neoplastic facts unlike; diagnosis was really challenging and finally spontaneous remission was observed after several months. Clinical and histopathological findings made idiopathic orbital inflammatory syndrome the most probable diagnosis for our patient.
