Background: Ocular sebaceous carcinoma (OSC) is a malignant and potentially lethal sebaceous gland tumor. Clinically, it masquerades as other benign and less malignant lesions, resulting in a delay in diagnosis.
Methods: In the present study, we sought to evaluate the cytomorphology of this aggressive neoplasm diagnosed by fine-needle aspiration cytology (FNAC) last year at our institute.
Results/findings: We report three cases of OSC diagnosed on aspiration cytology showed a cellular smear composed of sheets, 3D clusters, papillaroid, and singly scattered polygonal tumor cells having centrally located hyperchromatic pleomorphic nuclei and multiple microvacuolations in the cytoplasm. Necrosis and crushing artifact were also identified. Special stains such as Oil Red O stain on air-dried smears showed positivity, confirming the presence of lipid globules. Subsequently, the Cytological impression of sebaceous carcinoma was confirmed on histopathology.
Conclusions: The article highlights the role of FNAC in the early and correct diagnosis of aggressive tumors and subsequent appropriate management to prevent recurrence and metastasis.
