Actinic keratosis is described as a precancerous lesion that is elevated pink scaly and can progress to squamous cell carcinoma.

• A. Elevated pink scaly precancerous lesion
• B. Benign nevus
• C. Pigmented mole
• D. Malignant melanoma

Answer: (A)

Actinic keratosis is a sun-damaged, precancerous change in keratinocytes that can progress to squamous cell carcinoma. It classically presents as an elevated, pink or flesh-colored, rough and scaly patch on sun-exposed skin, including the eyelids. The description that best captures both its appearance and its precancerous nature is an elevated pink scaly precancerous lesion. Benign nevus and pigmented mole describe noncancerous or melanocytic lesions that are typically pigmented and do not have the precancerous risk profile. Malignant melanoma is a cancer of melanocytes and usually appears as a pigmented, irregular, evolving lesion rather than a pink, scaly patch. Recognizing this presentation helps in early identification and management to prevent progression to squamous cell carcinoma.
