Which skin condition is characterized by yellow, waxy lesions?

• A. Actinic keratosis
• B. Seborrheic keratosis
• C. Basal cell carcinoma
• D. Melanoma

Answer: (B)

Seborrheic keratosis is characterized by yellow, waxy lesions that typically appear on the trunk, face, neck, and scalp. These benign growths have a distinctive waxy, wart-like appearance and can vary in color from light tan to black. They are often described as having a "stuck-on" look, which contributes to their distinctive recognition. The lesions can develop over time as skin cells accumulate and undergo abnormal growth without any associated pain or discomfort.

Understanding seborrheic keratosis is essential because it is a common skin condition often seen in older adults and is usually harmless. This condition can sometimes be mistaken for other skin lesions, making it vital for individuals to have any persistent changes in their skin evaluated by a healthcare provider.
