A cyst is a closed sac-like structure that can be filled with liquid, semisolid, or gaseous material. Cysts can occur anywhere in the body and vary in size from microscopic to large masses that can displace internal organs.

Classification

Cysts can be classified based on their location, cause, and the type of material they contain. Common types include:

• Epidermoid cyst
• Pilonidal cyst
• Ovarian cyst
• Baker's cyst
• Ganglion cyst

Pathophysiology

Cysts form when the normal flow of fluid is obstructed, leading to the accumulation of fluid and the formation of a sac. This can occur due to:

• Blockage of ducts
• Infections
• Genetic conditions
• Chronic inflammatory conditions

Symptoms

The symptoms of a cyst depend on its location and size. Common symptoms include:

• A noticeable lump or bump under the skin
• Pain or discomfort
• Redness or swelling if infected
• Functional impairment if pressing on organs or nerves

Diagnosis

Diagnosis of a cyst typically involves:

• Physical examination
• Ultrasound
• CT scan or MRI for deeper cysts
• Biopsy if malignancy is suspected

Treatment

Treatment options depend on the type and location of the cyst. They include:

• Observation for asymptomatic cysts
• Surgical removal for symptomatic or large cysts
• Aspiration for fluid-filled cysts
• Antibiotics if the cyst is infected

Complications

Potential complications of cysts include:

• Infection
• Rupture
• Recurrence after removal
• Malignant transformation (rare)

Prevention

Preventive measures depend on the type of cyst. General recommendations include:

• Maintaining good hygiene
• Regular medical check-ups
• Managing underlying conditions

Prognosis

The prognosis for cysts is generally good, especially if they are benign and treated appropriately. However, some cysts may recur or cause complications if not managed properly.
