 
Squamous Cell Carcinoma
Advanced squamous cell carcinoma at the upper eyelid and within the eye.
Malignant and metastasizing tumour of the skin and the mucous membrane. It develops from
a pre-stage (carcinoma in situ) and occurs often at mucous membrane and at the change-over from skin to
mucous membrane (edge of the eyelid- conjunctiva – eye).
Divers rays, carcinogenic substances, papilloma virus and skin alterations which are
chronically phlogistic play a decisive role in the development of a squamous cell carcinoma.
A variant is the spino-cellular carcinoma which also grows relatively fast, ulcerating
and similar to warts. It destroys soft tissues, cartilage and bones. It metastasizes into regional lymph
nodes and later into other vital parts. The prognosis depends on the position, bigness, depth and the degree
of differentiation of the tumour.
In the region of the eyelids and the eyes, a longsome redness or irritation which is
resistant to therapy, ought to be examined by an ophthalmologist. A histological analysis should also be
included.
After a squamous cell carcinoma is histological confirmed, one has to begin a local
surgery. Further the total body has to be examined concerning metastases. In the case of a positive
verification of metastases a systemic therapy has to follow.
