Mole that itches: what to do?

Moles are small pigmented spots that appear on the skin. They result from a localized accumulation of melanocytes, the cells responsible for the production of melanin, the pigment that colors the skin. Moles can be present from birth - this is then referred to as a congenital nevus - but, most often, they appear during childhood or adolescence. Most nevi are benign but they still need to be closely monitored to ensure they do not transform into a melanoma.

Moles typically do not cause itching.

That's why when it happens, it can be a cause for concern. However, in most cases, this sensation is caused by a irritation due to repeated friction, such as that generated by clothing (collars, belts, straps...). These areas of friction can irritate the skin, including where the mole is located. Furthermore, a skin dryness, common in winter or following the use of overly harsh products, can also cause itching and redness around the mole. In these situations, it's not the mole itself causing the itch, but rather an irritation of the surrounding skin.

It can also occur that a mole becomes the site of local inflammation, for example due to a bug bite. It's an unfortunate coincidence that the irritation manifests precisely at this location. In addition to itching, the area around the mole can become red and swollen, which can cause concern. The inflammation usually subsides on its own within a few days. In the meantime, it's important not to scratch or manipulate the lesion, to avoid worsening it. However, if the itching or irritation persists and if the mole shows unusual changes, such as a change in color, size, or texture, this could be a sign of a malignant transformation.
