Sažetak
Canine follicular tumours (CFT) are an uncommon type of keratin-producing tumours in dogs that develop from different structures of the hair follicle. CFT are classifi ed as infundibular keratinizing acanthoma (IKA), tricholemmoma, trichoepithelioma, pilomatricoma and trichoblastoma. Studies on CFT are rare and most descriptions of these tumours are presented as case reports. Thus, we performed a retrospective study to investigate the prevalence and types of CFT within the Croatian canine population. The study included all CFTs presented to the Department of Veterinary Pathology in a 4 year period (2009 to 2012). In the investigated period, 714 skin tumours were diagnosed, from which only 69 presented as CFT: 10 IKA, 21 pilomatricoma, 1 malignant pilomatricoma, 12 trichoepithelioma, 4 malignant trichoepithelioma and 21 trichoblastoma. No breed or gender predisposition was found. However, pilomatricoma was mostly diagnosed in breeds with continuous hair growth, while IKAs were mostly found in breeds without continuous phase hair growth coats. Tumours were mostly presented as nodules and rarely as warts or plaques, growing in the dorsal aspect of the skin on the head, back and hind legs. CFT still represent a small number of tumours compared to other types of neoplasia diagnosed in Croatian canine patients. In the majority of cases, these tumours consist of a benign proliferation. However, in 7.2 % of CFT an infi ltrative malignant form was diagnosed. Keratin-fi lled skin nodules are therefore required for histopathological evaluation to avoid the unfavorable consequences of malignant spread.
