Being told that you may have a sebaceous gland carcinoma (SGC) of the eyelid can understandably be worrying. Sebaceous gland carcinoma is a rare form of eyelid cancer that develops from the oil-producing glands of the eyelids, most commonly the meibomian glands.
Although uncommon, SGC can be a serious condition because it may mimic benign eyelid problems, leading to delays in diagnosis. With prompt specialist treatment, however, many patients achieve excellent outcomes.
Early diagnosis, appropriate surgery and structured follow-up are key components of successful management.
Sebaceous gland carcinoma is a rare cancer arising from sebaceous (oil-producing) glands within the eyelid.
These glands are normally responsible for producing oils that help maintain a healthy tear film.
The tumour most commonly develops in:
Meibomian glands
Glands of Zeis
Sebaceous glands within the eyelid skin
The upper eyelid is affected more frequently than the lower eyelid because it contains a greater number of meibomian glands.
Sebaceous gland carcinoma (SGC) is an uncommon eyelid cancer and its behaviour can vary significantly between patients.
Some tumours are diagnosed at an early stage and are straightforward to manage, whilst others may require more extensive surgery, reconstructive procedures, imaging or multidisciplinary treatment.
Because of this variation, information provided on this website should be viewed as a general guide only and cannot predict the behaviour, stage or prognosis of an individual tumour.
Your consultant will discuss the findings that are specific to your diagnosis and explain how these may influence your treatment recommendations.
We recommend a specialist assessment if you notice:
A recurrent chalazion (cyst) that keeps returning
Persistent eyelid thickening
Loss of eyelashes affecting part of the eyelid
Chronic unilateral blepharitis that does not respond to treatment
A yellowish or firm eyelid lump
An eyelid lesion that has been gradually enlarging
Asymmetry or distortion of the eyelid margin
Book an Eyelid Oncology Consultation
Early diagnosis can improve treatment options and reduce the risk of local spread.
