Combination of squamous cell carcinoma and basal cell carcinoma arising from a giant verruca vulgaris involving the eyelid.

Purpose: Verruca Vulgaris is a common benign cutaneous lesion which only reported occasionally to have malignant potential. Our purpose is to report a rare case of verruca vulgaris involving the eyelid and subsequently transformed into the combination of squamous cell carcinoma and basal cell carcinoma.
Observations: We reported a case of a 97-year-old female with a chronic biopsy proven verruca vulgaris involving the left lateral canthus. She presented with pain and swelling 5 years after the biopsy. Physical examination showed a painful warty crushed growth mass surrounded by erythematous skin changes, sized 40 × 40mm. Excisional biopsy showed squamous cell carcinoma and a microscopic focus of basal cell carcinoma.
Conclusions and Importance: Our case demonstrates the oncogenic potential of verruca vulgaris into the combination of squamous cell carcinoma and basal cell carcinoma within one lesion. Size, chronicity and UV radiation may increase the risk of malignancy. Early surgical excision should be considered in eyelid involving chronic verruca vulgaris.
