Background: Axial pattern flaps use direct cutaneous arteries to enable closure of a skin defect using a large skin segment. Caudal epigastric axial pattern flaps are highly versatile owing to their wide arc of rotation, which includes the preputial area. The presence of abundant loose and elastic skin allows wider flaps. Hemangiosarcoma (HSA) is a malignant neoplasm of endothelial cells with aggressive local behavior and high metastatic rate; the lungs are the most common site of metastasis. This case report aims to describe the use of a caudal epigastric artery-based flap, with preservation of some cranial epigastric artery branches for penis sparing, following resection of a hemangiosarcoma in the right inguinal region of a male dog. Case: An eight-year-old male Pitt Bull dog was referred with a 15 cm, ulcerated hemangiosarcoma in the right inguinal region, near the prepuce. A similar tumor had been removed from the same location two years before. Previous treatment with oral prednisone did not provide satisfactory results. The patient was suffering from intense chronic blood loss and bacterial infection of the tumor tissue. Thoracic radiographs revealed multiple metastatic nodules. Only mild regenerative anemia was found in blood tests. Considerable reductions in tumor size and in the ulcerated surface, decrease in bleeding, and recovery of appetite were observed after 7 [...](AU)
