“…As in other species, fibromatoses in horse principally affect skeletal muscles. 6,11,15 In 2 young horses, the cervical and the pectoral musculatures were affected; the presence of fluidfilled cavities associated with sterile inflammation suggested a possible traumatic origin in those cases. Surgical excision was possible in 1 case and seemed to have been curative.…”

A 6-year-old Haflinger mare was presented with a history of recurrent hemoabdomen. On necropsy, a firm infiltrative multinodular yellow mass was observed in the wall of the posterior abdomen. Histopathologic examination revealed a proliferation of fibroblastic cells, which were positive for a-smooth muscle actin and vimentin.Keywords abdominal wall, desmoid fibromatosis, horse, immunohistochemistry, myofibroblastic proliferation Case HistoryA 6-year-old, 454-kg Haflinger mare was examined at the Centre Hospitalier Universitaire Vétérinaire of the University of Montreal with a 24-hour history of lethargy and anorexia. The mare presented with dullness, muscular fasciculations, and profuse sweating. The rectal temperature was 37.9 C, heart rate was 100 beats per minute, and respiratory rate was 44 respirations per minute. A large amount of abdominal fluid was observed by ultrasonography, which on analysis was consistent with hemorrhagic effusion (PCV [Packed cell volume], 50%; total protein concentration, 5.9 g/dl). No neoplastic cells were seen on cytologic evaluation of the fluid. Four days after admission, a second abdominal ultrasonography revealed the presence of a large oval solid mass measuring 9 Â 15 cm in the right caudal abdomen. On transrectal examination, the mass was firm, lobulated, nonmobile, and adhered to the abdominal wall. The following day, the mare became lethargic and anorexic, and euthanasia was performed.At necropsy, mild subcutaneous edema was present in the ventral aspect of the posterior abdomen. The abdominal cavity contained blood-tainted ascites (approximately 2.5 liters). A protruding mass measuring 10 Â 15 Â 8 cm was present in the abdominal wall, on the right posterior area close to the umbilicus (Fig. 1a). It was firm, infiltrative, multinodular, and yellow (Fig. 1b). The variably sized nodules were separated by a moderately abundant connective tissue. Hemorrhagic foci less than 2 cm in diameter were observed in the mass. Voluminous vessels were present at its base. Soft hemorrhagic projections 3 to 4 cm in diameter were extended into the abdomen. No other gross abnormality was observed in the mare. Differential DiagnosesThe differential diagnoses considered in view of the gross observations were fibroma, desmoid fibromatosis, rhadomyoma, mesothelioma, hemangioma, hemangiosarcoma, giant cell tumor of soft parts, and fibrosarcoma. Microscopic FindingsHistologically, the mass was unencapsulated and had no distinct borders. It was infiltrative and composed of bundles and sheets of densely packed fusiform cells forming collagen (Fig. 2a). The fibroblastic cells had a scant basophilic cytoplasm, with an elongated pale basophilic nucleus and 1 small eosinophilic nucleolus. No anaplastic features or mitosis were observed. A progressive maturation was present, with the density of cells becoming less as the density of the collagen was higher. Strands of dense collagenous tissue divided the mass in nodules. Mononuclear inflammatory cells and siderophages were present in zones of edem...

“…The pathogenesis of this lesions are unknown, but dog may develop suffering from serious illness such as chronic renal disease (11). It is occurred mostly in horse (between 1 and 13 years old), large dog breeds (<2 years old) which localized in pad nodullary (3,8,10). Pathogenesis is still unclear, but it has been thought due to trauma or excessive secrection of apocrin glands in dog and horse (5,6,9,10).…”

Summary:In the case, calcinosis circumscripta are described with macroscopical and microscopical findings on proximal of right limb in a 2.5 years old, male Rotweiller dog. Macroscopically, all masses were covered with skin and had firm. The cut sections were seen lobullary and composed of well defined areas and vicious and white fluid. Microscopically, it was detected that numbered of restricted areas, where the center had calcification in dark blue stained as haematoxylin eosin (HE) and red stained with Alizerine red S., connective tissue and mononuclear cell infiltration consisting of macrophages, lymphocytes and plasma cells and giant cells.

“…Synovial hemangioma can be classified as the deep hemangioma including usually skeletal muscle, or rarely bone, nerve, lymph node or synovium [4]. In young horses, synovial hemangioma has been recognized in carpal and digital tendon sheaths [5]. In human medicine, hemangioma of bone constitutes 1% of all primary bone tumors [9].…”

Synovial Hemangioma Accompanied by Cruciate Ligament Injury in a Dog

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...
