  Abstract 


We report an invasive type of ocular surface squamous neoplasia (OSSN) in a patient with congenital ichthyosiform erythroderma. A male patient aged 44 years, with ichthyosis presented with progressively growing right corneal mass, with decreasing vision. He was clinically diagnosed as OSSN and treated with local excision, conjunctival cryotherapy, and ocular surface reconstruction with amniotic membrane graft. Histopathological examination of the excised specimen confirmed the mass as a well-differentiated squamous cell carcinoma with invasion into the corneal stroma. Postoperatively, ocular surface reconstruction was achieved, and visual acuity improved from only perception of light to counting fingers one meter due to dense corneal scar. Postoperative central corneal scar with thinning was noted. Early age of onset and progression of OSSN in such patient with ichthyosis, recommend the need for screening in patients with congenital ichthyosis. Early treatment can prevent visual disability and permanent sequelae due to corneal scar.

  Introduction Top


Ocular surface squamous neoplasia (OSSN) is a rare ocular surface pathology, seen often as growth in the interpalpebral area adjacent to the corneoscleral limbus. Increased risk of OSSN has been reported to be associated with exposure to sunlight, HIV human papillomavirus, and immunosuppression following organ transplantation.[1],[2],[3] The known dermatological problem which is reported to predispose to OSSN has been the xeroderma pigmentosa. It is reported in 10% cases of xeroderma pigmentosa.[4] Increased frequency of early onset of OSSN in patients with xeroderma pigmentosa necessitating lifelong care has been emphasized.[5] OSSN may coexist with pterygium, and sometimes both may be related as they share ultraviolet (UV) exposure as a risk factor.[6],[7] Unexpectedly, high incidence of OSSN in pterygium in a place with low UV exposure has been reported suggesting the need for histopathological examination of the specimen after every pterygium excision.[8] Association of OSSN in patients with generalized ichthyosis has not been reported in the literature so far. We here in report, a case of OSSN in a 44-year-old patient with congenital ichthyosis.


  Case Report Top


A 44-year-old male patient presented with progressive loss of vision in the right eye (RE) for 1 year, which was preceded by a growing mass in the RE, since 4 years. He noticed a small whitish nodule adjacent to the side of the RE cornea 4 years back, which was slow growing with foreign body sensation. There was no pain or discharge. He revealed the presence of dry, scaly skin all over the body since birth not associated with itching or pain or any discharge from skin lesions for which he did not take any treatment as they are asymptomatic. He is a farmer by occupation. Takes mixed diet, not an alcoholic or smoker. On general examination, erythematous skin with thin white scaly lesions was seen all over the body with alopecia and madrosis, suggestive of congenital ichthyosiform erythroderma [Figure 1] and confirmed by dermatologist consultation. On ocular examination, OD has a perception of light positive and projection of rays accurate in all quadrants. It had ectropion with cicatrization of upper palpebral conjunctiva, keratinization of bulbar conjunctiva, and symblepharon superotemporally. Pink whitish mass with patchy brown pigmentation with irregular lobulated surface encroaching the corneal surface measuring about 10 mm × 5 mm [Figure 2] was seen in OD. A dilated tortuous feeder vessel from the conjunctival side was present. Anterior chamber details, pupil, lens, and fundus details were obscured. On palpation, under topical anesthesia the mass was soft in consistency, freely movable on the conjunctival side of the lesion and firmly attached to underlying structure on the corneal side. OS showed symblepharon on lateral side of lower lid, lower punctal aplasia, pseudopterygium on temporal side, rest of the anterior segment was normal and dilated fundus examination was normal. In OS, the uncorrected distance visual acuity was 20/20, with near visual acuity of N10.

Clinical examination led to the provisional diagnosis of OSSN in OD. Ultrasound biomicroscopy of RE showed no invasion into the anterior chamber. MRI of the orbit showed irregular lobulated lesion on RE anterior ocular surface with no extension into the orbit or surrounding soft tissue. Symblepharon release, excision biopsy of the mass lesion, double freeze-thaw cryotherapy of the conjunctiva, with reconstruction of the ocular surface with amniotic membrane transplantation in OD was planned. After obtaining written informed consent, under strict aseptic conditions, under peribulbar anesthesia the mass was excised with margins including 3 mm clear area surrounding the mass. After confirmation from histopathological report that margins are free of tumor cells, denovo excised margins of the conjunctiva were thawed with double freeze-thaw technique with cryoprobe. Corneal side lesion was managed with partial keratectomy. Conjunctival defect and the corneal surface were covered with amniotic membrane graft and secured with 6–0 vicryl sutures. Histopathology of the main mass confirmed as an invasive well-differentiated squamous neoplasia with keratin pearls and pigment-laden macrophages [Figure 3].

Postoperatively, in OD topical moxifloxacin 0.5% eye drops q. i. d and topical predacetate 1% eye drops q. i. d for 4 weeks and topical Mitomycin-C 0.04% eye drops with 1 week on and 1 week off for 3 cycles were prescribed. Topical tear substitute eye drops every 2 hourly in both eyes were prescribed. The patient was followed up from day 1 to 7, weekly for 1 month and monthly for 6 months. The necessity for lifelong follow-up was explained to the patient. Impression cytology of the pterygium in the other eye was carried out to rule out any subclinical OSSN. No recurrence was noted in 6 months duration; however, thinning of corneal stroma [Figure 4] was noted for which tissue glue was applied and advised for localized patch graft. Visual acuity was counting fingers one meter at 1-month follow-up and remained so due to dense corneal scar. There were persistent scar and no recurrences at 3 months' follow-up.

  Discussion Top


Congenital ichthyosiform erythroderma is one of the five distinct forms of ichthyosis.[9] Usual ocular associations in Ichthyosis are – ectropion, blepharitis,  Meibomian gland More Details absence, trichiasis, madarosis, absence of lacrimal puncta, keratinization and thickening of conjunctiva, and limbal stem cell deficiency.[9] Enlarged corneal nerves is a uniform finding in all forms of ichthyosis. Cornea may show recurrent corneal erosions, band keratopathy, Salzmann nodules, stroma vascularization, unilateral megalocornea, and rarely microphthalmos and anterior chamber cleavage syndrome. Retina may show coloboma, retinitis pigmentosa, maculopathy, and tortuous vessels. Increased risk of various malignancies in ichthyosis was reported such as squamous cell carcinoma (SCC) of larynx, nasal ala, vulva, penis, oral mucosa, multiple aggressive cutaneous malignancies, and uterine SCC.[10],[11],[12],[13],[14],[15]

This is the initial report of invasive SCC of the ocular surface to be reported in a patient with ichthyosis. Depending on the features such as scarring alopecia, ectropion, punctal aplasia, keratinization of conjunctiva and with generalized red skin with thin white scales all over the body, the congenital ichthyosiform erythroderma confirmed by the dermatologist. Ectropion causing exposure keratopathy, severe limbal stem cell deficiency could be the cause of the symblepharon. The patient being a farmer might have had been exposed to UV light in the open fields for many years. Other risk factors like UV light exposure for SCC cannot be rule out in this case. As the left eye presently has pterygium, the lesion in RE also might have started as pterygium initially, and OSSN might have developed from preexisting pterygium later transforming into invasive SCC. Since the patient was treated in the late stage of the disease, even though the surgical excision was successful; the visual prognosis has been poor due to the dense central scar. Although only one case is reported and further studies are required to give an association between ichthyosis and OSSN. Nevertheless, we can conclude that this case report helps to prompt physicians, dermatologists, and ophthalmologists to advise screening and regular lifetime follow-up for early detection and treatment of OSSN to prevent subsequent SCC in a patient with ichthyosis. This can aid eventually preventing the visual disability and permanent sequelae.
