What are Red Moles?
Moles is the popular term for melanocytic nevi - are skin lesions characterized by congestion in the epidermis and dermis of many melanocytic cells (cells that produce brown-black skin pigment). Red moles are generally benign, but some of them may turn into melanoma - the most aggressive malignant skin tumor metastasis with a high capacity and causing a fatal end.
There are several types of red moles. Some are present from birth or occur shortly afterwards and are called congenital melanocytic nevi. Other nevi may occur after age 1 and are called acquired melanocytic nevi. This classification is important because congenital melanocytic nevi have more processing capacity in melanoma.
How do normal moles look like?
Moles are well defined lesions of the skin they have a symmetrical layout and have round or oval shapes. The most common moles are flat, seen as changes in skin color. Other moles are papilomatoase (finger-shaped knob) or hemisferic issue. Some may be pedicled (base implantation miele small compared with the rest of the body lesion), others may have a smooth surface. Some moles have hair on their surface. The mole's color is highly variable, but it is immediately noticed if there is more than one color on the same mole.
The most encountered color is dark brown, brown or even black. There are also red moles, pink, blue, brown. Some moles may have a red halo, while others may have a white halo, its width can be increased even while sometimes lowering the Nevus which surrounds it. These changes do not suggest a malignant lesion or a transformation.
Moles are asymptomatic lesions. No pain, burning, tingling or itching. In case of symptoms, dermatological consultation is required in time to be excised before the development of melanoma.
When can a mole get malignant?
Moles can change the meaning of malign when they suffer an attack. This may be a trivial scratch, bite, cut (generally, an event leading to bleeding from the lesion), may be a chemical attack (tars, acids, bases, etc.). The aggression may be an ultraviolet light (natural, the sun or artificial level of special lamps). Be noted that UV rays is cumulative over time and therefore is considered the leading cause of malignancy.
Most common malignant process occurs after the age of 40 years, favorite locations are the thorax back in men and on the legs in women. It is important to perform regular monitoring of red moles to any change in shape, size or color. Most changes in red moles are benign, as determined by normal growth, benign (non-cancerous) cells of the pigment in the skin. However, it is recommended to call your doctor if you notice any abnormal changes in the formations.
Your doctor will ask you, the patient, about recent changes in the formations and about the time when they occurred. He will ask about family history-side to assess the risk of developing a melanoma.
If minor changes occur, your doctor will make photos of the nevus, which can be used for further evaluation. If there are signs of malignant transformations, your doctor might recommend taking a biopsy (a portion of formation) or excision of the faction entirely. They can perform a surgery clinic. Portion of skin will be sent to a histopathology laboratory for examination under a microscope for signs of malignant transformation.
If there is suspicion of a malignant transformation of nevus, ask your plastic surgeon or the dermatologist (skin disease specialist), to perform an appropriate treatment. It may consult a specialist pigmented lesions, which can identify and diagnose melanoma. Probably there will be two appointments, one for examination by a physician faction, the second for its surgical excision.
On the number of red moles, it is considered that there may normally be 100 moles on the body. If the numbers are more than 100 a dermatological advice is recommended and monitored 2 times per year to capture a possible pre-malignant change.
