Which description best fits seborrheic keratosis?

• A. Waxy, raised, or wart-like lesion on the surface of the skin.
• B. Flat pigmented macule with irregular borders.
• C. Ulcerated lesion with rapid growth.
• D. Skin lesion with hair loss around it.

Answer: (A)

Seborrheic keratosis is a common benign skin growth that presents as a waxy, stuck-on, raised or wart-like surface. This description captures its characteristic texture and appearance—well circumscribed, often pigmented, and hanging onto the skin like a waxy plaque. It’s different from flat pigmented macules with irregular borders, which suggest melanoma or lentigo, from ulcerated lesions with rapid growth, which raise concern for malignant cancers, and from lesions with surrounding hair loss, which points to other dermatologic conditions. So the description that fits best is a waxy, raised, or wart-like lesion on the surface of the skin.
