“…Since the first case was described by Bouchut in 1856, fewer than 200 cases have been reported [10]. Canine synovial hemangioma is not a commonly recognized one and has been reported in only two dogs [1,4]. Furthermore, even if hemangioma is a common skin or subcutis tumor, dogs are unlikely to develop juvenile hemangioma in skin, subcutis or deeper tissue [4].…”

“…Usually, the dog associated with synovial hemangioma presents with a history of recurrent atraumatic bloody effusions [1,4]. The diagnosis is often based on evidence of a soft tissue mass on radiographs concurrent with hemarthrosis; however, a soft tissue mass evident on radiographs and hemarthrosis can be identified in the more common canine articular tumors such as histiocytic sarcoma, myxomas, fibrosarcoma, hemangiosarcoma and osteosarcoma [1,2,4]. In this case report, there was evidence of a soft tissue mass on radiographs; however, no hemarthrosis was identified on synovial fluid aspiration.…”

ABSTRACT. We report here the clinical presentation and successful surgical management of synovial hemangioma accompanied by cruciate ligament injury in a dog. Surgical correction of cruciate ligament injury was performed after removing torn cruciate ligaments, synovial mass and masses attached to the ligaments and distal femoral articular cartilage. At 10 months, the dog has showed no evidence of recurrence in the stifle joint. Synovial hemangioma, although a seemingly rare cause of stifle joint pathology, should be considered in the differential diagnosis for cruciate ligament injury when a circumscribed intra-articular soft tissue mass is evident radiographically with cranial or caudal drawer motion. This is the first case report in a dog to describe synovial hemangioma accompanied by cruciate ligament injury. In canine joints, synovial histiocytic sarcoma and synovial sarcoma are considered the most common tumors, followed by synovial cell sarcoma, myxomas, malignant fibrous histiocytoma, undifferentiated sarcoma, fibrosarcoma and chondrosarcoma [2]. Vascular tumors are common in the skin and subcutis; however, rarely recognized in the canine synovium [4]. In humans, synovial hemangioma is a rare benign vascular tumor and most commonly involving the knee [6]. To the authors' knowledge, canine synovial hemangioma has been described in only two case reports [1,4]. The purpose of this case report is to describe the clinical presentation and successful surgical management of synovial hemangioma accompanied by cruciate ligament injury in a dog. This is the first case report in a dog to describe synovial hemangioma accompanied by cruciate ligament injury.A 27-kg, 5-year-old, intact female Jindo dog was presented for evaluation of progressive left pelvic limb lameness of a few weeks' duration. The owner reported that the dog showed initial lameness on a walk. On physical examination, the dog was reluctant to walk and showed non-weight bearing lameness. Soft tissue swelling around the stifle joint and marked muscle atrophy of the left pelvic limb were obvious. There were both cranial and caudal drawer signs with pain that was elicited on the left stifle joint manipulation. Mediolateral radiographic projection of the left pelvic limb revealed a well-defined mass with soft tissue opacity in the proximal aspect of the infrapatellar fat pad, caudal tibial displacement in a plain view and cranial subluxation of the tibial tuberosity in a stress view (Fig. 1). There was no evidence of hemarthrosis on synovial fluid aspiration. Synovial fluid cytology revealed predominant lymphocytes and no tumor cells.Surgical exploration of the stifle joint was performed through an arthrotomy lateral to the patellar ligament. Pedunculated masses located in the proximal aspect of the infrapatellar fat pad were attached to the synovial membrane, cruciate ligaments and distal femoral articular cartilage (Fig. 2). Cranial and caudal cruciate ligaments injury and degenerative changes including cartilage defects were identified (Fig. 2). Masses...

“…12 In human beings and dogs, synovial hemangiomas are most commonly reported in the stifle joint. 1,5,10 In the literature, it is unclear whether these lesions represent true neoplasms or vascular malformations (hamartomas), but the occurrence in young horses favors the classification as vascular hamartomas. 2,11 The lesions are characterized by slow growth and, in some cases, infiltration of adjacent structures.…”

A 15-year-old gelding presented with a progressive lameness of the left forelimb of 2.5 months duration. Clinically, a dilation of the deep flexor tendon sheath with a firm elastic consistency and a pronounced tenderness was noted. Ultrasonically, a marked swelling of the flexor tendon sheath with an irregular density of the mesotendineum was observed. The white, firm material forming a nodular distension of the flexor tendon sheath with a diameter of approximately 1 cm was excised and sent for histopathological examination. Biopsies of the deep flexor tendon and corresponding tendon sheath were sent for histopathological evaluation. Histologically, the mass consisted of clefts and numerous anastomosing vascular channels extending between the collagen fibers of the deep flexor tendon. These capillary-like spaces were lined by neoplastic cells that were flattened to polygonal and contained few erythrocytes. There was 0 to 1 mitotic figure per 10 high power fields (400×). Immunohistochemically, the neoplastic cells stained positive for vimentin and factor VIII–related antigen. Adjacent to the neoplastic endothelial cells located pericytes expressed α-smooth muscle actin antigen. Based on the histopathological and immunohistochemical features, synovial hemangioma was diagnosed. One year after surgery, the horse has shown no lameness.
