TRICHOEPITHELIOMA IN A DOG (CLINICAL CASE)

Abstract

The article presents a clinical case of trichoepithelioma in a male Baron of the Bernese Zinenhund breed aged 8 years. It has been shown that the establishment of a definitive diagnosis of skin neoplasms in dogs requires a comprehensive clinical, instrumental and morphological examination. After taking an anamnesis and conducting a clinical examination, the animal was found to have a solitary nodular formation of the skin of a dense consistency, without signs of pain, with slow progressive growth. The general condition of the animal was assessed as satisfactory. The purpose of our study was to study the clinical, morphological and histological features of trichoepithelioma in a specific clinical case and to assess the effectiveness of an integrated approach to the diagnosis and treatment of skin neoplasms. For diagnostic purposes, general and biochemical blood tests, cytological examination of the punctate of the neoplasm, X-ray and CT examinations were performed. The final diagnosis was established on the basis of the results of histological examination after surgical removal of the tumor, which confirmed its origin from the epithelium of hair follicles, characteristic of trichoepithelioma. In this case, an important point is that a benign tumor (trichoepithelioma) has an invasive growth, which negatively affected the health of the animal. The main method of treatment is surgical removal of the neoplasm within healthy tissues. In the postoperative period, the animal is prescribed antibiotic and anti-inflammatory therapy, as well as analgesics, taking into account body weight and general condition. Particular attention is paid to the control of surgical wound healing and the prevention of postoperative complications. The treatment provided a complete clinical recovery of the animal. The postoperative period proceeded without complications. The dog was discharged in satisfactory condition. Owners are provided with recommendations for regular clinical monitoring in order to timely identify possible recurrences of skin neoplasms. The data of our research are of practical value, show positive results in the comprehensive diagnosis and treatment of trichoepithelioma.
