Which lesion is a precursor to squamous cell carcinoma?

Explanation:
Actinic keratosis is a sun-damaged lesion from atypical keratinocytes that remains confined to the epidermis but carries a risk of progression to invasive squamous cell carcinoma. The small islands of dysplastic keratinocytes and solar damage signal a premalignant state, and with time or additional UV exposure, these lesions can invade to form SCC. In contrast, basal cell carcinoma arises from a different cell lineage and rarely progresses to squamous cell carcinoma; melanoma comes from melanocytes; and seborrheic keratosis is a benign growth with no malignant potential to become SCC.
