For example, itchy or inflamed lesions are more characteristic of conditions like eczema or contact dermatitis, which can cause irritation and inflammation that are not typical of seborrheic keratosis. Scaly patches that bleed easily might suggest actinic keratosis or other more concerning skin lesions, rather than seborrheic keratosis, which is generally asymptomatic and does not typically bleed. Fluid-filled blisters, on the other hand, are indicative of conditions such as herpes simplex virus infections or contact dermatitis, which are quite different from the benign nature of seborrheic keratosis.
