Seborrheic keratoses are the most common benign tumor in older individuals.
Seborrheic keratoses have a variety of clinical appearances, as seen in the images below, and they develop from the growth of epidermal cells.
Although no specific etiologic factors have been identified, they occur more frequently in sunlight-exposed areas.
Although lesions may resolve on occasion, spontaneous resolution does not ordinarily occur. Seborrheic keratoses usually begin with the appearance of one or more sharply defined, light brown, flat macules. The lesions may be sparse or numerous.

The color of the lesions can vary from pale brown with pink tones to dark brown or black.
A familial trait exists for the development of multiple seborrheic keratoses in about half of the patients, with an autosomal dominant mode of inheritance.
