Sebaceous carcinoma of the eyelid diagnosed on fine needle aspiration cytology

Abstract

Sebaceous carcinoma of the ocular adnexa is a malignant neoplasm which has aggressive local behavior and can metastasize to regional lymph nodes and distant organs. It is a malignant neoplasm known to masquerade as other benign and less malignant lesions, resulting in delay in diagnosis and relatively high morbidity and mortality. Aspiration cytological features of this neoplasm have not been well characterized in the literature. We report a case of this tumor diagnosed on fine needle aspiration. Clinically, a diagnosis of chalazion was made and fine needle aspiration cytology (FNAC) was performed. Cytological diagnosis of a malignant tumor with closest resemblance to sebaceous carcinoma was suggested which was confirmed on histopathology. Eyelid reconstruction was done after histopathological confirmation of tumor-free margins. The article highlights the role of FNAC in early diagnosis and subsequent appropriate surgical management of eyelid sebaceous gland carcinoma to prevent recurrence and metastasis.
