Skin Lesion

A Skin Lesion (/ˈskiːn ˈliːʒən/) is a part of the skin that has an abnormal growth or appearance compared to the skin around it.

The term "lesion" comes from the Latin word "laesio" which means "an attack or injury" which is derived from laedere - "to hurt, strike or wound".

There are two main types of skin lesions, primary and secondary.

Primary Lesion - These are abnormal skin conditions that have been present since birth or acquired over a person's lifetime. They include birthmarks, moles, and warts.

Secondary Lesion - These are the result of irritated or manipulated primary lesions. Examples include scars, crusts, and ulcers.

Skin lesions can be caused by a variety of factors including infection, inflammatory processes, tumors, and genetic factors.

Diagnosis of skin lesions often involves physical examination, dermatoscopy, and possibly biopsy. Treatment depends on the cause of the lesion and may include topical medications, systemic medications, or surgical procedures.
