Noncancerous growths or tumors of the skin fall into two categories.
Benign and Premalignant Tumors
are benign growths originating in the epidermis, clinically appearing as tan-brown, greasy papule or plaques
Seborrheic Keratosis
are benign asymptomatic and can be found on any part of the body, particularly on the front of the lower leg. thought to be caused by fibrous reactions to viral infections; scaly, hard growths that are slightly raised and pinkish brown
Dermatofibroma
benign epithelial growth that may be caused by a virus and generally is seen in people in their 60s. smooth, red, dome-shaped papule with central crust that usually appears singly but may occur in multiple numbers
Keratocanthoma
occur secondary to trauma or surgery. large and thick skin growth. cause pruritus and sometimes deformities
Keloids and Hypertrophic Scars
develop when a sebaceous gland slowly fills with a thick fluid. commonly found on the scalp, face, base of ears, and the chest
Epidermal (Sebaceous) Cyst
are common benign skin growths or tags. painless and usually caused by friction, they are found mainly in the axilla, on the neck, and on inguinal areas of the body

Non-Melanoma Skin Cancers
is the most serious of the three types of skin cancer, but it is not as common. arises in epidermal melanocytes, cells that make the brown pigment, melanin
Malignant Melanoma
skin normally contains special cells called melanocytes that produce melanin, a black pigment that gives color to the skin. results when there is too few or too many or a disturbance in melanocytes
