Sebaceous carcinomas that develop on an eyelid often cause a slow-growing lump to form. It may appear yellow or firm and is often painless. Sometimes, you have to stretch your eyelid to see it. You may also notice:
Growth that bleeds
Sore that will not heal or reappear
Thickening or yellow or reddish crust, where the eyelid meets the lash
Later, the cancer may:
Look like pink eye or a stye
Cause additional growths that may open and ooze
Hurt your eyesight
The majority of eyelid growths are non-cancerous or caused by other conditions, but it is still important to see a doctor.
Elsewhere on the body, sebaceous carcinoma may look like a slow-growing pink or yellowish lump that may bleed.
