In most cases skin pigmentations are without consequence.
Nevertheless, in the presence of brown spots, it is essential to consult a doctor to have an accurate diagnosis.
Aside from the naevi (moles), pigmentary lesions can be :
– Senile lentigines
Commonly called "age spots", appear between 30 and 40 years old and sit on the photo-exposed areas: face, forearm, back of the hands, décolleté and shoulders.
– Hyperpigmentation spots
May appear during pregnancy (melasma or pregnancy mask), on scars or following a trauma or medical procedure; they sit anywhere on the body.
– Stains secondary to a fungal infection
