Seborrheic keratoses are an annoyance. Lesions can itch and rub or catch on clothing, thereby becoming inflamed.

Lesions often are unattractive and have negative psychological connotations—daily reminders of aging.

Patients are sometimes concerned that these enlarging lesions are malignant. Sometimes a person that has many seborrheic keratoses may not notice a dysplastic nevus or a malignant melanoma that develops among the seborrheic keratoses. A significant danger can arise if a person fails to detect a malignant melanoma at an early stage.
