Trichoepithelioma in dogs

Species: Dog
Condition: Trichoepithelioma
Organ System: Urogenital

A benign tumour of the cells that are developing into hair follicles. It is common in dogs, usually affecting animals older than 5 years. There are certain breeds that are predisposed to trichoepithelioma. It is believed that this predisposition is genetically transferred. The tumour appears as a single firm nodule on the trunk or the limbs, 1 to 2 cm in diameter, white to grey, sometimes with ulcers. In order to determine the diagnosis, the vet will take tissue sample of the tumour and examine it cytologically. Due to its benign nature, the tumour causes no discomfort or any heath issues. However, it is recommended to remove it surgically.
