Reconstrução cirúrgica utilizando dos retalhos de padrão subdérmico em cão acometido por sarcoma hisórico em região da cabeça: Relato de caso

Abstract

Histiocytic sarcoma is a rare and highly aggressive malignant neoplasm that originates from interstitial dendritic cells, typically affecting middle-aged to elderly dogs. This paper describes the case of a dog diagnosed with histiocytic sarcoma in the head region, an uncommon location that presents significant challenges for surgical management. Due to tumor progression, complete surgical removal was performed, followed by advanced tissue reconstruction techniques using two types of subdermal flaps: transposition and neck advancement flaps. These techniques allowed effective coverage of the surgical defect, ensuring both the preservation of functionality and the maintenance of aesthetics in the affected area. Postoperative management involved intensive care to prevent infections and complications, resulting in satisfactory recovery for the patient. This case highlights the importance of a multidisciplinary and personalized approach in the treatment of complex neoplasms in dogs, emphasizing the crucial role of flap reconstruction techniques in veterinary surgery. The success of the intervention demonstrates that these techniques are essential for improving the quality of life in patients, especially in cases of aggressive, infiltrative, and difficult-to-treat tumors, such as histiocytic sarcoma in the head region.
