Sebaceous Cyst

Sebaceous cyst is a benign noncancerous skin lesion, it is broadly divided into epidermoid cyst and pilar cyst which originate in the epidermis and from hair follicles respectively. So technically speaking they are not truly from sebaceous glands. 

They are commonly found in scalp, ears, back, face, chest and upper arm, though they may occur anywhere on the body except the palms of the hands and soles of the feet. If it happens to the scalp, there may be a patch of baldness just over the cystic area. They are smooth to the touch, vary in size, and are generally round in shape.

They are generally mobile masses consisting commonly the following contents :

  • Fibrous tissue and fluids,
  • A fatty (keratinous) substance that resembles cottage cheese, in which case the cyst may be called "keratin cyst". They smell "cheesy" or even worse as foot odour.
  • A somewhat viscous, serosanguineous fluid (containing purulent and bloody material).

Sebaceous cyst may sit at the sites for long time before it became infected resulting in abscess formation requiring drainage.

A cyst can usually be excised in its entirety with surgical excision under local anesthesia. However, some patients have a predisposition to cyst formation, further cysts may develop in the same general area.

    Surgical Excision

    Apart from CO2 Laser, some warty lesions, moles, nevus and skin polyps can be removed surgically. For sebaceous cyst, surgical excision under local anesthesia is considered the better option.


    Reminders:

    • Medical consultation is advised for better understanding the procedure in terms of nature, steps and possible surgical risks.
    • Skin lesions will be marked out and anesthetized locally
    • Skin lesions will be removed surgically
