Mole Check

What device is used for mole check up?

Dermoscopy or Dermatoscopy is a noninvasive method that allows the in vivo evaluation of colors and microstructures of the epidermis, the dermoepidermal junction, and the papillary dermis not visible to the naked eye. These structures are specifically correlated to histologic features.

A handheld instrument called a dermatoscope or dermoscope, which has a transilluminating light source and standard magnifying optics, is used to perform dermoscopy.

A dermatoscope allows dermatologists to distinguish benign from malignant tumors, particularly in the diagnosis of melanomawithout the obstruction of skin surface reflections. Other cancerous lesions that can be diagnosed by dermatoscopy include angiomas, basal cell carcinomas, cylindromas, dermatofibromas, seborrheic keratosis and squamous cell carcinomas. Also it can determine the surgical margin for skin cancers that are difficult to define. Bowen’s disease, lentigo malignas and superficial basal cell carcinomas fall under this category because they are known to have indistinct margins.

Dermatoscopy is also used in the diagnosis of fungal infections, hair and scalp diseases (including alopecia areata,female androgenic alopecia, monilethrix, Netherton’s syndrome and woolly hair syndrome), pubic lice, scabies and warts.

What should you look for when examining moles?

The following ABCDEs are important signs of moles that could be cancerous. If a mole displays any of the signs listed below, have it checked immediately by a dermatologist:

• Asymmetry
• One half of the mole does not match the other half.
• Border
• The border or edges of the mole are ragged, blurred, or irregular.
• Color
• The mole has different colors, or it has multiple shades of tan, brown, black, blue, white, or red.
• Diameter
• The diameter of the mole is larger than a pencil eraser.
• Elevation/Evolution
• The mole becomes elevated (raised off the skin), or the mole is changing.

You should always be suspicious of a new mole that develops after the age of 30. Many of the growths that appear after the age of 30 are harmless age-associated growths rather than moles; however, if you do notice a new growth, you should see your dermatologist. The most common location for melanoma in men is the back; in women, it is the lower leg. Melanoma is the most common cancer in women ages 25 to 29.
