Dermatology is the branch of medicine, involving the medical and surgical management of the conditions of the hair, scalp, skin and nails. Conditions of the human dermis constitute a spectrum of dermatoses as well as nonpathologic states like racquet nails and melanonychia. The diagnosis of these is made by gathering information regarding the skin lesion(s), symptoms, morphology, duration, color, etc. Nail diseases are determined by an inspection of pliability, color changes and markings, shape and texture.
