Squamous cell carcinoma (SCC or SqCC), occasionally rendered as “squamous-cell carcinoma”, is a histologically-distinct form of cancer. It arises from the uncontrolled multiplication of transformed malignant cells showing squamous differentiation and tissue architecture. Squamous cell carcinoma is one of the most common cancers, and frequently forms in a large number of body tissues and organs, including skin, lips, mouth, esophagus, urinary bladder, prostate, lung, vagina, and cervix, among others. Despite the common name, squamous cell carcinomas often show large differences, depending on where they develop, in their presentation, natural history, prognosis, and response to treatment

• After administration, change gloves prior to applying occlusive dressings to injected lesions. Wipe the exterior of occlusive dressing with an alcohol wipe. It is recommended to keep injection sites covered with airtight and watertight dressings at all times, if possible. To minimise the risk of viral transmission, patients should keep their injection site covered for at least 8 days from the last treatment or longer if the injection site is weeping or oozing. Advise patients to apply dressing as instructed by the healthcare professional and to replace the dressing if it falls off.

Cornea transplantation is sometimes required for lesions that cause severe cornea thinning and loss of structural integrity of the eye. Scars that are visually significant and refractory to medical therapy and/or hard contact lenses may require transplantation. Vitrectomy / Retina detachment surgery may be performed especially in cases of acute retina necrosis (ARN). Glaucoma filtration surgery is sometimes performed if there are difficulties with maintaining optimum intraocular pressure. If the intraocular inflammation and/or steroid treatment causes a cataract then cataract surgery may be performed when the disease process is quiescent.

Herpetic stromal keratitis is treated initially with prednisolone drops every 2 hours accompanied by a prophylactic antiviral drug: either topical antiviral or an oral agent such as acyclovir or valacyclovir. The prednisolone drops are tapered every 1–2 weeks depending on the degree of clinical improvement. Topical antiviral medications are not absorbed by the cornea through an intact epithelium, but orally administered acyclovir penetrates an intact cornea and anterior chamber. In this context, oral acyclovir might benefit the deep corneal inflammation of disciform keratitis. [6]

The mainstay of therapy is antiviral treatment either in the form of topical therapy with trifluridine 1% eight to nine times a day or oral administration of acyclovir or valacyclovir for 10 to 14 days. If trifluridine drops are used, care is to be taken to ensure antiviral drops are discontinued within 10-14 days due to corneal toxicity. Epithelial debridement of the dendrites may also be utilized in conjunction with antiviral therapy to help reduce viral load. Topical corticosteroids are contraindicated in the treatment of active HSV epithelial keratitis.
