Squamous Cell Carcinoma
A tumor is an abnormal growth of any tissue or structure; it can be either benign or malignant. A tumor can affect any part of the eye, such as the eye socket, eyeball, eye muscles, optic nerve, fat, and tissues.
Squamous cell carcinoma is a malignant eyelid tumor, occurring in approximately 5% of malignant eyelid tumors. The most common location is the lower eyelid, particularly in elderly, fair-skinned people. This tumor appears as a raised nodule, and it can lead to loss of eyelashes in the involved area.
When detected and treated early, the outcome for this type of tumor is excellent. However, if the tumor is neglected, it can spread to the lymph nodes in the neck. Surgery is the most effective treatment.
