title: Orbital sarcoma in HIV positive patient: a diagnostic dilemma.
abstract: Diagnosis of a high-grade sarcoma on fine needle aspiration cytology (FNAC) may not pose any difficulty; however, further sub-typing is sometimes difficult. The clinical data, investigations, and finer points on cytomorphology may help for proper categorization of the tumor, however, we encountered a case of orbital sarcoma in an Human Immunodeficiency Virus (HIV) positive patient, in which further sub-typing was difficult even on histopathology and immunohistochemistry was helpful. The diagnostic difficulties on FNA cytology smears as well as histopathology are highlighted.
