Basal Cell Carcinoma (BCC) - Periocular
What is Basal Cell Carcinoma (BCC))?
This is the most common malignant skin tumour in Caucasians and around the eye in general. However, it very rarely metastasizes, with an incidence this happening of less than 0.1%. It arises from the basal layer of the epidermis (the top layer of the skin). It is very slow growing and is most common on the lower eyelid.
What are the symptoms?
It doesn’t cause any pain but it can bleed sometimes. It is characterised as a lesion around the eye area that isn’t resolving.
What are the risks?
UV light exposure is a risk factor for developing a BCC. This commonly stems from an early age. For example, in Australia, there are around 850 cases per 100,00 people. Age is a risk factor, as well as being more common in females. People who work outside, those with a fair complexion, those with a previous history and the immunocompromised can be predisposed to BCC’s.
What does it look like?
There are varying appearances. It commonly has a nodular pearlescent appearance with visible blood vessels. This can ulcerate with rolled sides, giving a crater appearance. Very rarely, it looks like a flat plaque. If on the eyelid margin, this can cause lashes to fall out.
How is it treated?
If a BCC is suspected, biopsy can rule out or confirm diagnosis. Then radiotherapy or surgery are normally very successful treatments.
