A benign epidermal tumor that commonly presents in people over the age of 50. Sharply-defined brown lesion with a "stuck on" appearance.
A greasy, oily wart. They are benign but occasionally a squamous cancer has been reported to develop within a seborrheic keratosis. Therefore, careful, close examination is necessary to be sure that all is well. Seborrheic keratosis may arise from lentigos (age freckles) or may start on their own, growing usually as a greasy, stuck-on brown, tan or black wart-like growth. If examined very closely under a magnifying glass, miniature white or light horn pearls (tiny, white beads of keratin that can fit on the tip of a pen) may be noticed within the seborrheic keratosis. Very rarely will seborrheic keratoses develop a malignancy within. Because seborrheic keratoses are so common, there is also a possibility that one or more may collide merely by chance with a skin cancer growing nearby. Many times patients confuse seborrheic keratosis with melanoma and go to a doctor for examination. A thorough examination by an experienced doctor is usually a reliable way to tell the difference. Unfortunately, there is a type of melanoma known as verrucous melanoma that can mimic seborrheic keratosis. Fortunately, however, this is an extremely rare event.
a skin condition characterized by circumscribed wartlike lesions that can be itchy and covered with a greasy crust

A skin condition characterized by a benign overgrowth of cells with increased sebum production.

A Seborrheic keratosis is a benign skin growth that is very common among people over 40 years of age. The growths resemble flattened or raised warts, but have no viral origins and may exhibit a variety of colors, from pink or yellow through brown and black. Because only the top layers of the epidermis are involved, seborrheic keratoses are often described as having a "pasted-on" appearance.
