Abstract:
Neoplasia is an important concern for all researchers because of its increasing prevalence throughout the country and is a major cause of animal death. A study was conducted to assess the incidence of various types of tumours in dogs among which hair follicle tumours attributed to around 10.33% of all the cases. Histopathologically, the tumours were identified as trichoblastoma (ribbon type and medusa type) (n=4), trichofolliculoma (n=1) and tricholemmoma (n=1). Primarily an involvement of hair matrix cells, infundibulum along with isthmus is found in trichoblastoma, tricholemmoma and trichofolliculoma respectively. All are uncommon benign dermal tumours with breed, hair coat and unknown etiologies.
