Benign to malignant: A unique case of squamous cell carcinoma masquerading as papilloma

The clinical appearance of eyelid tumors many times may not concur with the final histopathological diagnosis. A 61-year-old female presented with a hyperpigmented mass in the right upper eyelid of 2-month duration. Clinically, it appeared to be squamous papilloma, a benign lesion. She underwent complete surgical excision of the mass. Histopathologically, the lesion was found to be squamous cell carcinoma, a malignant lesion. There was no recurrence of the mass until the last follow-up. This case report highlights the role of histopathology in aiding the diagnosis of eyelid swellings.
