Özet
İnfundibular keratinize akantom (IKA) köpeklerde kıl folliküllerinden köken alan iyi huylu deri tümörüdür. Bu çalışma 4 yaşlı erkek bir terrier köpekte IKA tanımlamaktadır. Makroskopik olarak birkaç aydır hayvanın arka tarafında, deride düzensiz yüzeyi ve ortası gözenekli yapıda olan kubbe şeklinde, 2-3 cm çapında sert kıvamlı yapı vardı. Histopatolojik incelemede lameller yapıda konsantrik keratinle dolu geniş bir kistin dermis ve hipodermis içerisine doğru uzandığı görüldü. Kistin duvarı çok katlı skuamöz keratinize eipitelle döşeliydi. Bir veya iki hücre kalınlığındaki epitel hücre kordonları kist duvarının perifer bölgesinden dışarıya doğru yayılmıştı. Epitel hücreleri iyi difensiye olmuştu. Mitoz nadirdi ve pleomorfizm yoktu.
Infundibular keratinizing acanthoma (IKA) is a benign cutaneous tumor in dog originated from the hair follicle. The present study describes IKA in a 4 year old, male terrier dog. Macroscopically, a cutaneous dome-shaped nodule, 2-3 cm in diameter, with firm consistency, irregular surface and a central pore was located on the back for several months. The histopathological examination revealed a large cyst filled with concentric lamellar keratin that extended into the dermis and hypodermis. The wall of the cyst was lined by the stratified squamous keratinizing epithelium. Cords of epithelial cells had one or two cells thickness expanded outward from the peripheral zone of the cyst wall. The epithelial cells were well-differentiated. Mitosis was rare and there was not polymorphism.
