Atypical Moles - Symptoms and Treatment

Atypical moles also called as Clark's nevi or dysplastic nevi, is a disorder of the skin characterized by the presence of many mole-like tumors. The skin cells that produce pigment i.e. melanocytes, which sometimes group together to form moles. But sometimes melanocytes can form abnormal moles, which are generally called as atypical moles. These moles are not malignant themselves, but their presence is a warning of an inherited tendency to develop melanoma. A When looking at an atypical mole on the skin, one will see some of the features that one sees when looking at melanoma such as: an irregular border, slight variation in color, or asymmetry. Generally most of the people people have 10-20 moles over their bodies. But People with this disorder found to have more than 100 moles, at least some of which are unusual in size and structure. They are usually larger than normal moles and have irregular borders. These type of moles are generally seen on the back but may appear anywhere on the body, including below the waist, on the scalp, on the breasts or buttocks. There are chances that they may fade into surrounding skin into a flat portion. People suffering from atypical mole are at a greater risk of developing cancer of the skin in the form of malignant melanoma. Also known as Clark`s nevi or dysplastic nevi, these moles are considered to be precancerous and they are more likely to convert into melanoma. Most of the experts are of the opinion that an atypical mole is at a higher risk of converting into melanoma as compared to a normal mole. A change in the appearance of the moles must be taken seriously by the patients as it may be an indication of onset of cancerous disease. Although the initial diagnosis is based on physical examination but a biopsy is required to be done in order to make the precise diagnosis.

Atypical Moles is basically a skin disease typical to youth, but Atypical Moles may occur to the people at any age. While atypical moles are considered to be pre-cancerous (more likely to turn into melanoma than regular moles), not everyone who has atypical moles gets melanoma. In fact, most moles both ordinary and atypical ones never become cancerous. Thus the removal of all atypical nevi is unnecessary. In fact, most of the melanomas found on people with atypical moles arise from normal skin and not an atypical mole. Also people with atypical moles should have annual eye exams, as ocular melanoma is also a big risk in these cases. One should be followed closely with a very low threshold to biopsy any lesion remotely suspicious. Getting detailed body photographs are an excellent way to follow moles to see if any are changing.
