What is Surgery – Sebaceous Cyst Removal

What is Surgery – Sebaceous Cyst Removal 

DEFINITION 
A blocked hair follicle causes an epithelium-lined, keratinous, debris-filled cyst. Epidermal cyst is the correct term. 

AETIOLOGY 
The pilosebaceous gland is occluded. Common in Gardner's syndrome.

EPIDEMIOLOGY
Is quite common in people of all ages. 

HISTORY 
Skin swelling that is non-tender and grows slowly, frequently in multiples. If there is a superimposed inflammation or infection, the skin may become red, hot, and painful. 

EXAMINATION
Overlying punctum on a smooth tethered mass in the skin. Hair-bearing parts of the body, such as the scalp, trunk, and scrotum, are common. It's possible to get granular creamy stuff with an unpleasant odour. 

PATHOLOGY/PATHOGENESIS 
These cysts are not made up of sebaceous glands, despite their name. The cystic growth of epidermal cells within the dermis causes sebaceous cysts. The infundibulum of the hair follicle is frequently the source of this epidermis. 

INVESTIGATIONS 
In most cases, none is required. FNA or excision biopsy are only used in rare cases. 

MANAGEMENT 
Conservative: If it isn't causing the patient any discomfort, it can be left alone. Surgical: Cyst excision can be performed under local anaesthetic. If the cyst is not completely removed, it is likely to return. If an abscess forms, it should be drained. Antibiotics may be provided if there is an infection; nevertheless, once the acute inflammation has subsided, the definitive therapy is excision. 

COMPLICATIONS 
Infection leads to the creation of an abscess. If the excision is not complete, the cyst will return. It's possible that it'll ulcerate and seem like a skin cancer (Cock's unusual tumour). If the discharged fluids dry out and create a horn-shaped protrusion, a sebaceous horn may arise. PROGNOSIS: Good; most don't need therapy, and excision is usually curative.
