What is the main characteristic of seborrheic keratosis?

Seborrheic keratosis is primarily characterized by its warty, raised appearance, which often features a texture that can be rough or scaly. These growths tend to have a stuck-on look, with colors ranging from light tan to dark brown or black. They usually develop on the face, chest, shoulders, and back, and are common in older adults.

The other options describe conditions that are quite different from seborrheic keratosis. Red, itchy patches are more indicative of dermatitis or eczema. Skin peeling is typically associated with conditions like psoriasis or certain infections rather than seborrheic keratosis. Pustular lesions are usually indicative of acne or infections like folliculitis, which do not relate to the benign nature of seborrheic keratosis. The unique warty appearance is a key hallmark that distinguishes seborrheic keratosis from other skin lesions.
