Dermatology is a medical specialty that focuses on the skin, mucous membranes, hair, and nails. Although the skin is a relatively simple organ to inspect, it is the largest organ and has a wide range of potential disorders - there are over 1500 different skin diseases and many variations. A dermatologist is a specialist who specialises in the treatment of problems and diseases of the skin, hair, nails, and mucous membranes. They can also help to revive the appearance of the skin, hair, and nails by addressing cosmetic concerns. Molecular studies in Dermatology and Dermatopathology covers the fundamentals of molecular biology and the most prevalent molecular diagnostic procedures used in clinical laboratories, with a focus on dermatological disease concepts and testing. This crucial diagnostic tool summarizes the therapeutically relevant applications of various procedures in dermatology (i.e., diagnostic, staging, and/or prognostic). Molecular research that looks into the development of skin diseases will be excluded unless they can also be used as a diagnostic tool.
