Abstract

An intraocular melanocytic tumor was described in the eye of a 6-year-old, gray coat Arabian horse. Clinical, microscopical and macroscopical examination revealed that the tumor showed invasion to all of the ocular compartments as well as to nasal and dorsal regions. Microscopically; the tumor was poorly delineated and consisted of round, polygonal and spindle cells with having a different amount of melanin content. Secondary ocular changes including corneal ulceration, fibrinous plug, keratinization, vascularization, neutrophilic keratitis and pre-iridial fibrovascular membrane were also detected. There was no evidence of recurrence, metastasis or dermal melanoma development within one year after the operation. Overall, the present report showed that diffuse equine intraocular tumor with extrascleral invasion could be successfully treated surgically with complete enucleation and exenteration of the orbit.

Özet

Altı yaşında, kır donlu bir Arap atında saptanan intraoküler melanositik tümör olgusuna ilgili morfolojik bulgular tanımlandı. Klinik, makroskobik ve mikroskobik muayenede tümörün tüm göz kompartımanlarına yayılmış olduğu ve gözün nazal ve dorsal alanlarında ise ekstra-skleral yayılım gösterdiği ortaya kondu. Mikroskobik olarak tümöral kitlenin sınırlarının tam olarak belirgin olmadığı, yuvarlak, poligonal ve mekik şekilli hücrelerden oluştuğu ve değişen derecelerde melanin pigmenti içerdiği tespit edildi. Kornea'da ülser, keratinizasyon, vaskülarizasyon ve nötrofilik keratitis ve pre-iridial fibrovasküler zar oluşumu gibi sekonder lezyonlara da rastlandı. Operasyonu takiben 12 ay içerisinde nüks, metastaz veya dermal melanom bulgularına rastlanmadı. Kır donlu bir Arap atında diffuz intraoküler melanositik tümör morfolojik bulguları ile ortaya konulmuş, ekstraskleral invazyona rağmen enükleasyon ve ekzenterasyonla başarılı bir şekilde tedavi edilebildiği sonucuna varılmıştır.
