Birthmarks are abnormal skin discolorations in spots that are either present at birth or appear shortly thereafter. They can be flat or slightly raised from the skin. They can be any number of colors, including red, brown, black, tan, pink, white or purple. Birthmarks are generally harmless. There are two major categories of birthmarks: pigmented birthmarks and red birthmarks.
Pigmented Birthmarks can grow anywhere on the skin and at any time. They are usually black, brown or skin-colored and appear singly or in groups. They can be moles (congenital nevi) that are present at birth, Mongolian spots, which look like bluish bruises and appear more frequently on people with dark skin, or café-au-lait spots that are flat, light brown or tan and roughly form an oval shape.
Red Birthmarks (also known as macular stains) develop before or shortly after birth and are related to the vascular (blood vessel) system. There are a number of different types:
- Angel kisses, which usually appear on the forehead and eyelids.
- Stork bites, which appear on the back of the neck, between the eyebrows on the forehead, or on eyelids of newborns. They may fade away as the child grows, but often persist into adulthood.
- Port-wine stains, which are flat deep-red or purple birthmarks made up of dilated blood capillaries (small blood vessels). They often appear on the face and are permanent.
- Strawberry hemangiomas, composed of small, closely packed blood vessels that grow rapidly and can appear anywhere on the body. They usually disappear by age nine.
- Cavernous hemangiomas are similar to strawberry hemangiomas but go more deeply into the layers of the skin. These can often be characterized by a bluish-purple color. They also tend to disappear naturally around school age.

Warts are small, harmless growths that appear most frequently on the hands and feet. Sometimes they look flat and smooth, other times they have a dome-shaped or cauliflower-like appearance. Warts can be surrounded by skin that is either lighter or darker. Warts are caused by different forms of Human Papilloma Virus (HPV). They occur in people of all ages and can spread from person-to-person and from one part of the body to another. Warts are benign (noncancerous) and generally painless. They may disappear without any treatment. However, in most cases eliminating warts takes time.
The location of a wart often characterizes its type:
Common warts can appear anywhere on the body, although they most often appear on the back of fingers, toes and knees. These skin-colored, dome-shaped lesions usually grow where the skin has been broken, such as a scratch or bug bite. They can range in size from a pinhead to 10mm and may appear singly or in multiples.
Filiform warts look like a long, narrow, flesh-colored stalk that appears singly or in multiples around the eyelids, face, neck or lips. They are sometimes called facial warts. They may cause itching or bleeding, but are easy to treat with over-the-counter medications.
Flat (plane) warts appear on the face and forehead. They are flesh-colored or white, with a slightly raised, flat surface and they usually appear in multiples. Flat warts are more common among children and teens than adults.
Genital warts appear around the genital and pubic areas. It is also possible to get genital warts inside the vagina and anal canal or in the mouth (known as oral warts). The lesions start small and soft but can become quite large. They often grow in clusters. They are both sexually transmitted and highly contagious. In fact, it is recommended you generally avoid sex with anyone who has a visible genital wart. Genital warts should always be treated by a physician.
Plantar warts appear on the soles of the feet and can be painful since they are on weight-bearing surfaces. They have a rough, cauliflower-like appearance and may have a small black speck in them. They often appear in multiples and may combine into a larger wart called a mosaic wart. Plantar warts can spread rapidly.
Subungual and periungual warts appear as rough growths around the fingernails and/or toenails. They start as nearly undetectable, pin-sized lesions and grow to pea-sized with rough, irregular bumps with uneven borders. Subungual and periungual warts can impede healthy nail growth. Because of their location, they are difficult to treat and generally require medical attention.
Most warts respond to over-the-counter treatments, including:
- Cryotherapy, which freezes off the wart using liquid nitrogen or nitrous oxide.
- Electrosurgery, which sends an electric current through the wart to kill the tissue.
- Laser surgery, which essentially heat up the wart until the tissue dies and the wart eventually falls off.
- Nonprescription freezing products (dimethyl ether), aerosol sprays that freeze the warts and cause them to die off.
- Salicylic acid preparations, which dissolve the protein (keratin) that makes up the wart and the thick layer of skin that covers it. It comes in gels, pads, drops and plasters and takes 4 to 6 weeks to eradicate the warts.
If self-treatments don't work after a period of about 4 to 12 weeks, contact our dermatologist. We'll assess your warts and recommend the best option.
Always contact the dermatologist if a wart is causing pain, changes in color or appearance and for all genital warts.
