Abstract

Hair follicular tumours (HFTs) are a relatively uncommon group of neoplasms in dogs, originating from the hair follicle structures. During the study period, 100 samples of tumour-suspected cutaneous masses were collected from dogs across the state of Kerala, India. The biopsy samples were screened histologically by routine haematoxylin and eosin staining. Immunohistochemistry and special histological staining were employed when required. Nine cases of HFTs were identified, of which six cases were trichoblastoma, two pilomatricoma and one trichofolliculoma. The study provided an overview of the occurrence of HFTs, including breed, sex, and anatomical location, along with details of their clinical characteristics, gross and microscopic pathology.

Keywords: Hair follicular tumour, trichoblastoma, pilomatricoma, trichofolliculoma, dog
