In: StatPearls [Internet]. Treasure Island (FL): StatPearls Publishing; 2023 Jan.


Seborrheic keratosis is a common type of epidermal tumor that is prevalent throughout middle-aged and elderly individuals. These lesions are one of the most common types of skin tumors seen by primary care physicians and dermatologists in the outpatient setting. Although seborrheic keratoses are benign tumors that often present with distinguishing features, there can be some morphological overlap with other malignant skin lesions. It is essential to recognize these features to differentiate these lesions from other benign and malignant skin tumors. Due to the benign nature of seborrheic keratosis, treatment is often not required. However, a majority of patients still opt to undergo some degree of treatment. Given the prevalence of these tumors, it is important to understand the workup and various treatment modalities for the management of seborrheic keratosis.
