Sebaceous gland carcinoma (SGC) is a rare malignant lesion that occurs on the eyelids. It is known to mimic other benign or malignant lesions in clinical presentation, such as a chalazion, basal cell carcinoma, and squamous cell carcinoma. The histopathological diagnosis is the mainstay for diagnosis and is often challenging.
CASE REPORT: We describe a case of SGC in a 53-year-old woman who presented with a cauliflower-appearing lesion with pearly telangiectatic vessels and raised margins at the lower eyelid margin. Clinically, we suspected a diagnosis of basal cell carcinoma. Upon complete resection of the lesion, the final diagnosis was SGC based on the histopathological features and immunohistochemical staining characteristics of the tissue.
CONCLUSIONS: Due to the possibility of SGC presenting similarly to other lesions, it is essential for ophthalmologists to have a high index of suspicion in its diagnosis. The early and accurate diagnosis of such lesions is important for appropriate management to prevent metastasis or recurrence related to advanced tumors.
