Final answer:

A cyst is a sac-like structure that can form on the skin or elsewhere in the body, often filled with fluid or pus. They can result from blocked glands or hair follicles and should be diagnosed and treated by healthcare professionals.

Step-by-step explanation:

A cyst is a closed capsule or sac-like structure, typically filled with liquid, semisolid, or gaseous material. Cysts can form anywhere on the body, including the skin. They are typically benign and can arise for various reasons, such as infections, chronic inflammatory conditions, or blockages of ducts in the body. In dermatology, they are often seen as fluid- or pus-filled bumps on the skin, which can be caused by blockages in the hair follicles.

A common example of a cyst in the context of skin conditions is a sebaceous cyst, which occurs when a sebaceous gland becomes blocked. Another type is an epidermoid cyst, which forms when skin cells multiply instead of sloughing off. These cysts can sometimes become inflamed or infected, leading to swelling or discomfort. Proper diagnosis and treatment by a healthcare professional are essential for managing cysts, as some may resemble other skin conditions or lesions.

Skin disorders and lesions, such as cysts, acne, abscesses, and various forms of skin cancer like melanoma, basal cell carcinoma, and squamous cell carcinoma, are important to differentiate as they can have differing causes, treatments, and implications for health.
