Topical mitomycin C treatment in corneal and conjunctival intraepithelial neoplasia: A case report

Öz

Corneal and conjunctival intraepithelial neoplasia is a slowly progressive ocular surface lesion with low malignant potential. Owing to the high recurrence rates, cryotherapy or topical chemotherapy is used with surgical treatment. In this paper, we report the histopathologic findings and treatment of a case of intraepithelial neoplasia that began in the conjunctiva and progressed to the cornea. A 75-year-old woman presented with complaints of redness, irritation and lacrimation in her left eye for around 1 month. Slit-lamp examination revealed a papilliform mass on the nasal conjunctiva along with involvement of the adjacent corneal epithelium. Conjunctival excisional biopsy showed a moderate epithelial dysplasia. Topical 0.04% mitomycin C was administered 4 times daily for 3 weeks. No recurrence was observed in the following 18 months.

Korneal ve konjonktival intraepitelyal neoplazide topikal mitomisin C tedavisi: olgu sunumu

Öz

Korneal ve konjonktival intraepitelyal neplazi, düşük malignite potansiyeli olan yavaş ilerleyen bir oküler yüzey lezyonudur. Yüksek nüks oranları nedeniyle kriyoterapi veya topikal kemoterapi cerrahi tedavi ile birlikte kullanılmaktadır. Çalışmamızda, konjonktivada başlayıp korneaya ilerleyen intraepitelyal neoplazili olgunun histopatolojik bulgularını ve tedavisini sunduk. Yetmiş beş yaşında kadın hasta yaklaşık 1 aydır devam eden sol gözünde kızarıklık, batma ve sulanma şikayetleri ile kliniğe başvurdu. Biyomikroskobik muayenede; nazal konjonktivada papilliform kitle ve bitişik kornea epitelinde tutulum mevcuttu. Konjonktival eksizyonel biyopsi sonucu orta derecede epitelyal displazi olarak raporlandı. Hastaya günde 4 defa, 3 hafta süresince topikal %0,04 mitomisin C uygulandı. Takip eden 18 aylık sürede nüks gelişmedi.
