3. seborrheic keratosis(English)

   • a benign intraepidermal neoplasm arising from epidermal keratinocytes. Very common in aging skin, developing typically on the trunk, head and neck, and in skin creases. Ultraviolet radiation exposure is considered the most important etiologic factor; other possible causes under investigation include genetic and metabolic factors. Several histologic subtypes have been described that give rise to a variety of clinical presentations.
