Dermatology is the branch of medicine that focuses on the study, diagnosis, and management of disorders of the skin. These include a multitude of conditions, from the very common acne vulgaris and burns to malignancy and the cutaneous manifestations of autoimmune diseases.

For optimal understanding, the student must be familiar with the histology of the skin, including its basic structure, types, and annexed components (follicles, sweat glands, and nails). Adequate study of skin lesions requires a paused process of observation to ensure greater retention.

Dermatologic conditions are a very common complaint around the world, as the skin is a very prized and sensitive component of an individual’s appearance and sense of self-worth. Since the patient can see the ailment constantly, it can be very distressing.

The competent physician must have an excellent “eye” for skin lesions and be able to differentiate between dermatologic conditions. Additionally, the clinician must also be knowledgeable of the dermatologic manifestations of systemic diseases, such as autoimmune conditions (e.g. systemic lupus erythematosus), metabolic conditions (e.g., acanthosis nigricans in diabetes mellitus), or malignancy (e.g. dermatomyositis in lung cancer).
