Congenital naevus. Close-up of dark brown raised birthmark or congenital naevus on human skin. Naevi are caused by overactivity or abnormality of melanocytes (skin cells that produce the brown pigment melanin). Most naevi are harmless and do not require treatment. However,if a naevus should suddenly appear,grow,start bleeding or change colour,medical advice should be sought to rule out the possibility of skin cancer | |
