Dermatological diseases and treatments



Moles, or melanocytic nevus, are benign tumours composed of clusters of nevus cells loaded with melanin. They usually appear after 6 or 12 months of age. However, some patients are born with them (congenital melanocytic nevus). They usually start out as a ‘spot’ that gradually increases in size. They are normally brown and can be different sizes. Although there are various factors that cause these lesions to change, such as exposure to the sun, puberty, and pregnancy, it is advisable to consult a dermatologist.
