Sebaceous Carcinoma

Sebaceous carcinoma (SC) is a less common skin cancer that commonly spreads if not treated early. 

These tumors are most commonly found on the eyelid and form a painless, round, firm growth. It may grow slowly and bleed. Another common area for this tumor is the nose.

MISTAKEN IDENTITY: STYE, CHALAZION, OR PINK EYE

​

There are many common growths that can develop on eyelids. These include: 

Stye: This is a hair follicle infection and is painful. If the infection occurs on the inside of the eyelid, it is called an internal hordeolum. Treatment is usually applying a warm compress 4 to 6 times a day. 

Chalazion: This is often painless and forms when an oil gland becomes blocked (and represents a cyst). Most clear with treatment, which includes warm compresses and antibiotic eye drops. 

Pink eye: (conjunctivitis) SC can look like pink eye that just won’t go away.

DIAGNOSIS AND TREATMENT

How does Dr. Andrew diagnose sebaceous carcinoma?

A skin biopsy is the only way to diagnose skin cancer. What Dr. Andrew removes will be examined under a microscope. 
 

How is sebaceous carcinoma treated?

Most patients diagnosed with SC are treated with surgery.

• Mohs surgery: To learn more this procedure, click here.

• Surgery to remove lymph nodes

• Radiation treatments

What outcome (prognosis) can a patient with SC expect?

When found early and treated, the prognosis is good. If the cancer spreads, then other treatments must be used to control the disease.
