Squamous Cell Ca involving lid and lateral canthus
Squamous cell carcinoma (SCC) is less common than Basal cell carcinoma (BCC) but potentially more aggressive and metastasis to regional lymph modes, it has predilection for the lower eyelid and the lid margin and commonly seen in elderly individuals. It occur in light skinned people who are exposed to large amount of total sunlight, thus the amount ultra violet exposure and skin type and color are the most important factors. It appear as crusting erosion and fissures, ulcers are typically shallow red base, sharply defined, indurated, elevated borders. Ulceration in SCC tends to occur than more rapidly BCC.
In the management of SCC, the precautionary majors to use protective clothing and pharmacologic sun-blocking agents should be recommended for all patient with a history of precancerous or cancerous skin lesions. complete surgical excision of lesion with frozen control is the mainstay of the treatment, with if required Radiation therapy, Cryotherapy or Chemotherapy may be required as adjunct therapy. In patient with local metastasis to local areas may require orbital exenteration with poor prognosis.
Entropion
The entropion is inrolling of lid margin along with eye lashes which rubs over the cornea. this causes extreme discomfort to the patient. this requires surgical correction by various techniques described in the literature. commonly done procedures are, Jones procedure with Lateral tarsal strip, depending upon the horizontal lid laxity.
