This study aimed to investigate the occurrence and histopathological features of neoplastic conditions in different species of animals that attending the Veterinary Teaching Hospital, College of Veterinary Medicine, University of Mosul. Samples had been collected from animals with variable neoplastic lesions. The results of this study showed that the total number of the excised tumours was 36, those were noticed in cattle 30.6%, sheep 22.2%, dog 10.4%, poultry 13.9%, cat 11.1%, and goat 2.8%. The tumours were diagnosed as squamous cell carcinoma 22.22%, fibroma 19.44%, adenoma 13.89%, pulmonary adenomatosis and fibrosarcoma 11.11%, leucosis and lymphoma 8.33%, thymoma, and transmissible venereal tumour 2.78%. We concluded from the current study occurrence a different type of tumours which was malignant or benign in different species of animals.

This study was designed to evaluate the using of two laparoscopic techniques for repairing an experimental cystotomy of urinary bladder reinforced with omental pedicle in dogs. Eighteen local breed male dogs were randomly allocated into two equal groups: first group an experimental cystotomy (about 2 cm) was induced laparoscopically at the ventral surface of the urinary bladder, repaired with titanium clips and reinforced with the omental pedicle. In the second group: similar technique was followed; however, the induced was repaired with hand-assisted extracorporeal laparoscopic method. In both groups, several diagnostic parameters were followed including clinical / laparoscopic exploration, radiology, and ultrasonography. Results obtained in the first group shown the titanium clips 4-6 clips freely applicated and whole time consuming for performing operation was 45±2.1 minutes. Clinically, the experimental animals didn't show any abnormal changes in their behavioral activities. Radiographic examination revealed distention of the urinary bladder accompanied by the presence of distances between the titanium clips; however, ultrasonography didn't show any leakage or thickness at the site of operation. Laparoscopic examination demonstrated mild adhesion between urinary bladder and adjacent organ. In the second group, the operation required 36±1.1 minutes to be completed. Postoperatively, no signs of pain were observed, however, animals demonstrated post-operative transient hematuria, lasts for 24 hours, accompanied with severe adhesion between the bladder and abdominal wall. Radiographically, regular distention of the bladder was revealed, while ultrasonographic examination showed hyperechoic dots and thickening of the bladder wall. We concluded that the hand-assisted laparoscopic cystorrhaphy strengthened by omentum is a practical, time saving and mini-invasive surgical technique.

The present article was aimed to assess the healing process of experimental entire rupture of Achilles tendon treated with various methods. The study was conducted on twenty-four healthy mature local breed dogs, which were randomly allocated in equal four experimental groups (6 of each). All dogs underwent complete Achilles tendon rupture and reconstructed as following: Group1 (control), animals were treated with tendorrhaphy only; Group 2, tendorrhaphy with platelet-rich plasma; Group 3, tendorrhaphy with a vein graft; and Group 4, the ruptured tendon was repaired with tendorrhaphy and augmented with vein and platelet-rich plasma. Dogs were monitored clinically and sonographically to evaluate tendon healing at 15, 30 and 60 days following the surgery. By comparison with the control group, the utilizing of plasma, with or without vein graft, enhanced the healing process of the induced rapture. Clinically, animals showed a fastest weight bearing and ultrasound imaging revealed increased echogenicity of fibrotic tissue. Clinically, the vein- platelet-rich plasma treated animal’s demonstrated early weight bearing, while animal treated with plasma showed earlier improvement in fiber pattern echogenicity. Furthermore, the using of vein graft for injury repair increased the repair process and the healing was earlier than that in the control group. In conclusions, our results suggested that the using of platelet-rich plasma with or without vein graft could enhance tendon healing and improve its mechanical function, which might be attributed to the synergistic effect of platelet-rich plasma with the vein graft.

A 2-year-old rooster local breed suffered from anorexia, emaciation with abnormal large mass in lateral side in cervical region was attended to Veterinary Teaching Hospital belong to College of Veterinary Medicine, Mosul University. After physical examination a movable and friable mass were recognized in cervical region. The case sends for surgical intervention. Gross examination of removed mass showed a friable, pale, will capsulated with hemorrhagic areas. Microscopically, the mass included three types of tumors. Squamous cell thymic carcinoma characterized by presence of keratin pearl. Lymphoma that characterized by atypical polymorphic lymphocytes, vesicular nucleus, and pyknotic nucleoli, while cytoplasm appears eosinophilic to granular with ill- define borders. Lipoma which appear as irregular shape of adipocytes that lack their nucleus, with scattered infiltration of pyknotic lymphocytes. This is the first pathological report of mixed tumor of thymus gland in rooster that composed from squamous cell thymic carcinoma, lymphoma and lipoma.
