Seborrheic KeratosesSeborrheic keratoses (seborrheic warts) are flesh-colored, brown, or black growths that can appear anywhere on the skin. The lesions commonly occur in middle or old age and most often appear on the trunk or temples; in blacks, especially women, small keratoses often occur on the malar part of the face (dermatosis papulosa nigra). A seborrheic keratosis usually appears as a brown, black or pale growth on the face, chest, shoulders and back. Occasionally, it appears singly, but multiple growths are more common. Typically, seborrheic keratoses don't become cancerous, but they can look like skin cancer. Their size also varies from very small to the size of a medium coin. These growths often look as though they have been pasted on. In general, seborrheic keratoses do not need treatment unless their appearance causes embarrassment or they become irritated by clothing. A health professional can remove these growths by freezing, burning, or scraping them off the skin. They may also be removed using a laser. All skin growths, especially those that appear suddenly or change in shape or color, should be evaluated by a health professional to rule out cancer. Seborrheic keratoses are benign plaques, beige to brown or even black, 3-20 mm in diameter, with a velvety or warty surface. Although these growths can appear anywhere, they most often appear on the torso and the temples. The cause of seborrheic keratoses is unknown, although the tendency to develop them may be inherited. It is possible that seborrheic keratoses are related to sun exposure. Seborrheic keratoses vary in size and grow slowly. They usually appear “stuck on” and may have a verrucous, velvety, waxy, scaling, or crusted surface. Diagnosis is clinical. They are not premalignant and need no treatment unless they are irritated, itchy, or cosmetically bothersome. Lesions may be removed with little or no scarring by cryotherapy (but beware risk of hypopigmentation) or by curettage after local injection of lidocaine Causes of Seborrheic KeratosesThe common Causes of Seborrheic Keratoses :
