Spread of conjunctival SCC can occur in 1–21% of cases, with the first site of spread being the regional lymph nodes. [1] Mortality for conjunctival SCC ranges from 0–8%. [1] Diagnosis is often made by biopsy, as well as CT (in the case of invasive SCC). Treatment of conjunctival SCC is usually surgical excision followed by cryotherapy. [1]
Pedicled skin flaps are a method of transferring skin with an intact blood supply from a nearby region of the body. An example of such reconstruction is a pedicled forehead flap for the repair of a large nasal skin defect. Once the flap develops a source of blood supply form its new bed, the vascular pedicle can be detached. [66]
The blood supply to the palpebral conjunctiva (the eyelid) is derived from the external carotid artery. However, the circulations of the bulbar conjunctiva and palpebral conjunctiva are linked, so both bulbar conjunctival and palpebral conjunctival vessels are supplied by both the ophthalmic artery and the external carotid artery, to varying ...

Basal cell carcinomas are the most frequently encountered kind of cancer affecting the eyelid, making up 85% to 95% of all malignant eyelid tumors. [5] The tumors may be benign or malignant.
