Abstract
- Seborrheic keratosis is one of the most common benign epithelial tumors, especially in elderly patients. Squamous cell carcinoma is the second most common malignant tumor of the skin. Despite the fact that both tumors are common, malignant transformation of seborrheic keratosis rarely occurs. Herein we report a case of squamous cell carcinoma arising in a patient with pre-existing seborrheic keratosis.
