A flat wart, or verruca plana, is a form of wart (verruca). Warts are common growths caused by an infection of the surface (superficial) skin with the human papillomavirus (HPV), which thickens the top skin layer. Warts are usually harmless and painless, and many go away on their own after months to years. In fact, two thirds of warts are gone within 2 years of their appearance.Warts are passed to humans by person-to-person contact or, rarely, by touching an object used by an infected person. Warts are not highly contagious and usually require a small break in the skin to become infected.Flat warts tend to stay small in size, but they can be numerous in quantity. Flat warts often spread to other places on the body by scratching or shaving.
Warts are growths of the skin and mucous membranes (the mouth or genitals) that are caused by over 100 types of the human papillomavirus (HPV). The virus causes thickening of the top skin layer. A plantar wart occurs on the sole of the foot. It can look and feel like a callus. Plantar warts can be small, or they can grow to cover most of the sole of the foot. They are usually painless and go away on their own, sometimes taking a few months to resolve (but can take up to 2 years).Warts are usually acquired from person-to-person contact. The virus is not highly contagious but can cause an infection by entering through a small break in the skin. In the same way, warts can be spread to other places on your own body. The virus is rarely transferred by touching an object used by an infected person.
Warts are growths of the skin and mucous membranes (the mouth or genitals) that are caused by over 100 types of the human papillomavirus (HPV). Common warts are usually found on areas of the body prone to trauma, such as the elbows, knees, and hands. The virus causes thickening of the top skin layer. They are usually painless and go away on their own, sometimes taking a few months to resolve, but can take up to two years.Warts are usually acquired from person-to-person contact.

Genital warts (condyloma acuminata) are caused by the human papillomavirus (HPV), which has over 100 different strains. Subtypes number 6 and 11 cause 90% of genital warts and are considered low risk because they very rarely will cause genital or anal cancer. On the other hand, subtypes 16 and 18, for example, are considered high risk because, although they rarely cause genital warts, they can lead to cervical or anal precancer and cancer. HPV is spread by skin-to-skin contact during sexual activity; there does not need to be vaginal or anal intercourse to spread the infection. Most people who become infected with HPV will not have symptoms and will clear the infection on their own. For people who do develop genital warts, there are many options for treatment, all of which are meant to remove the visible warts. There is no cure for genital warts. Gardasil® is a vaccine that protects against the 4 strains of HPV that cause 70% of cervical cancers and 90% of genital warts. In the US, Gardasil is approved for girls/women and boys/men ages 9–26. In 2011, Health Canada approved the vaccine for women up to the age of 45.
Molluscum contagiosum is a common painless and usually harmless viral infection of the skin. Although it is painless and usually goes away after several months, some cases can last a few years. Molluscum can spread to surrounding skin by scratching or rubbing and can spread to others by skin-to-skin contact or handling contaminated objects such as towels, toys, and clothing. Poor hygiene and warm, moist climates encourage the spread of molluscum. Use of public or school swimming pools is associated with childhood infections.
Molluscum contagiosum appears as small pearly, skin-colored, wart-like lesions all over the body. It is caused by a common virus and is spread by direct contact with other affected children, or by handling contaminated objects. Molluscum contagiosum is painless and usually harmless; it usually disappears in 6–9 months but could last for a few years. Children who are affected with molluscum contagiosum can spread the rash to other areas of their body by itching or rubbing the lesions.
Curettage, in dermatology, is a surgical procedure that uses a curette, a small scooped-shaped instrument, to scrape off noncancerous skin growths and certain skin cancers such as:Basal cell carcinomas Viral warts and noncancerous lesions smaller than 1 cm Seborrheic keratoses
Cryosurgery uses liquid nitrogen, a very low-temperature liquid, to destroy noncancerous (benign) and some cancerous (malignant) skin lesions. It is a common treatment option because of its low cost, ease of use, and effectiveness. When used by properly trained and experienced physicians, cryosurgery can remove a lesion with good cosmetic results.

September means back to school – the end of a busy summer vacation season and time for Mom and Dad to relax as the kids are occupied with new friends and activities. Sometimes the close contact that kids have with each other can lend itself to the development of some common childhood skin infections. Here we review some of the more common infections seen in this age group:
The most-searched skin condition on Skinsight this year was herpes, a lifelong skin infection caused by the herpes simplex virus (HSV). HSV infections are contagious and spread by skin-to-skin contact with the infected area. An estimated 10-60% of the general population is infected with genital herpes, and only 20% of those infected with HSV develop visible blisters or sores.
We’ve slathered them with sunscreen all summer and forced them to wear shirts and hats on the beach. Now, as we send them back to school, our kids may be exposed to common skin infections, more likely to break out in groups where they play, roughhouse, and sometimes share personal items.
Melanoma cancers are classified most frequently by their depth into the skin and the deeper layers of the skin. The pathologist reads the biopsy and measures the depth of the melanoma cancer cells under the microscope. There are several melanoma stages, an early melanoma is typically quite superficial. The hope is that people will recognize the early signs of melanoma, see their doctor, and have the lesion removed – and that the pathology report will reveal a melanoma that has not deeply invaded the skin. A melanoma that has not invaded into the deeper skin is called a “melanoma in situ.”
May is National Skin Cancer Awareness Month. We should feel proud that as a society, we have learned so much over the last generation about preventing, diagnosing, and treating skin cancer. However, research reveals that skin cancer awareness and education specific for African American skin is lacking. Most people are under the wrong impression that African Americans can’t get skin cancer. The good news is that skin cancer in the African American population is relatively low. The bad news, however, is that most African Americans suffer a significant delay in the diagnosis of the disease which results in greater difficulty in treating and curing the disease.
There are a few relatively common skin lesions that are painful or tender in children. Probably the most common cause of a painful bump in a child during the summer months is an insect bite reaction. Bees, wasps, hornets, and also spiders can cause acutely painful skin lesions.
Sexually transmitted diseases (STDs) are infections that are passed from person to person by sexual activity. Although STDs are most often spread through vaginal, anal, or oral intercourse, skin-to-skin contact is enough to transmit many STDs.
Itchy skin rashes are very common in the genital region, which generally includes the area below the belly button to the top of the legs: the buttocks the area around the anus, and the vulvar, penile, and scrotal areas.
Common causes of fingernail or toenail changes include trauma, aging, infection, and skin diseases. Diet is generally not responsible for abnormal nail changes, unless the person is suffering from severe malnutrition. Trauma can induce horizontal fingernail ridges (Beau lines), bleeding (hemorrhage) under the nail plate, and white streaks or spots (leukonychia).
Trauma, infection, skin disease, and even simply bearing weight on the feet can cause changes on the skin of the feet, including the toes and heel. Corns and calluses are an area of thickened skin caused by friction and pressure. Juvenile plantar dermatosis occurs in children on the sole of the front part of the foot and on the toes.
Sores on the lips and mouth are common and can be harmless or serious health problems. One must be sure to have a persistent mouth sore examined and diagnosed by an expert, because cancer of the lips with a basal cell or squamous cell carcinoma is common, particularly in older patients. Basal and squamous cell cancers can be symptomless, or can bleed and be sore.
Changes in hormone levels during pregnancy can produce a wide variety of changes in the skin, many of which are unavoidable. Most of these skin changes disappear on their own after childbirth. Pregnant women face many potential common skin changes, including stretch marks (striae), acne, a dark vertical line on the belly (linea nigra), darkening of many other skin areas (such as the area around the nipples, inner thighs and vulvae, and of pre-existing freckles and moles), mild itching, minor nail changes, morning facial swelling, red or itchy palms, and small dilated blood vessels (telangiectasias, or spider veins) of the face, neck, chest, and arms.
Many common dermatologic procedures are done as office procedures to test for a wide variety of diseases or to treat often minor dermatologic diseases or conditions in a quick and noninvasive manner. Some common dermatologic techniques used to test for diseases are biopsies, including punch, shave, and excision biopsy; microbiological culture (often called a skin culture); skin allergy patch testing, and Wood's lamp examination.
