  • A 9-year-old intact female Shih-Tzu was presented with abdominal pain and abdominal distension. Since the animal's birth, the owner had never observed proestrous bleeding in the patient. Ultrasonography revealed segmental enlargement of the genital system. An ovariohysterovaginectomy was performed to remove the genital mass. The vagina was grossly dilated as a result of being filled with a solid black-green substance. A vaginogram was performed. Based on the surgical findings and vaginogram results, an imperforate hymen was diagnosed. One month from the first surgery, a stump pyocolpos developed between the sutured site and the obstructed portion. The persistent hymen was removed by endoscopy. However, peritonitis and sepsis developed after the procedure, and the dog died. Therefore, During operation of persistent hymen, a cruciate incision over the hymen strongly recommended to avoid additional post operative complications.

  • Gastrointestinal stromal tumor (GIST) is one of the mesenchymal tumors originated from gastrointestinal submucosa. A 10 year-old, male, mixed breed dog with persistent diarrhea, anorexia and lethargy was referred to Haemaru Animal Referral Hospital. Large mass originated from the transverse colon was observed and large amount of ascites and free gas were found on abdominal radiography and ultrasonography. The ascites was septic exudate mixed with bacteria that consisted with intestinal perforation. There was no metastatic lesion. This mass was tentatively diagnosed as adenocarcinoma, leiomyosarcoma (LMS) and lymphosarcoma and surgical resection and histilogical examination were planned. However, according to owner's request, the patient was euthanized and then the necropsy was performed. About 10 cm sized mass originated from the cecum, ascending colon and transverse colon was adhered to surrounding mesentery and the perforation and large amount of ascites were observed. GIST was suspected on histopathologic examination and confirmed according to CD 117 expression in immunohistochemistry. GIST, derived from interstitial cells of Cajal, can be distinguished from LMS and leiomyoma (LM) on the basis of expression of CD117 (KIT) immunohistochemically. GIST has a different biological behavior and clinical course compared with LMS and LM, therefore definite diagnosis for GIST using immunohistochemistry is clinically important to predict the precise prognosis of the patient.

  • An eight-year-old, castrated male, a Schnauzer dog was presented with dysuria, hematuria and intermittent vomiting. Retrograde positive contrast urethrography was performed under fluoroscope. On the contrast examination, the leakage was observed in the prostatic urethra region and irregular filling defect was also shown from the prostatic urethra and the level of the trigon of the bladder. Surgical treatment was selected because of partial urethral obstruction and dysuria. The metastasis at the time of surgery was suspected, and the owner decided euthanasia. We detected lymph metastasis with immunohistochemical staining for pan-cytokeratins (CK) AE1/AE3, confirming their epithelial origin. This report described typical clinical findings, diagnostic imaging and histopathological examination of a prostatic adenocarcinoma.

  • An 11-year-old castrated male, Shih-tzu dog was admitted for progressive weight-bearing lameness and mass on the right hindlimb. Radiography and ultrasonography revealed a large well-marginated multinodular mass with mixed echogenicity. On T1 and T2-weighted magnetic resonance imaging (MRI), the mass has a heterogenous signal intensity similar to or higher than muscle. The masses were extended to the pelvic cavi쇼 through obturator foramen and displaced the rectum dorsally. It was diagnosed as synovial sarcoma which was composed with mesenchymal and epithelial elements on histopathological findings of the multifocal biopsied specimen. MRI was helpful to determine the definitive margin for surgical resection of the mass. The mass was recurred at the 6th month after surgery. On the 10th month, the patient was euthanasiuzed by owner's request.

  • A 3-year-old Cocker spaniel was presented for evaluation because of a mass protruding from the vulva. This mass confirmed the presence of an internal bone in clitoris on the radiography. We recommended to the owner of the surgical removal of the gonads and uterus as well as the excision of the enlarged clitoris and os clitoris. The dog had gonads in the region of where the ovaries were located and presented what appeared to be a bicornate uterus and ductus deferens. Histological analysis revealed a morphologically normal uterus and two testes with their epididymis and ductus deferens. Karyotyping revealed a normal female chromosome constitution (78, XX), and polymerase chain reaction (PCR) identified the absence of Sry. Based on these findings, the patient was diagnosed with Sry-negative XX sex reversal.

  • A 2.8-year-old intact female Beagle dog (weighing 11kg) was referred with the primary complaint of exercise intolerance with occasional syncope. Physical examination revealed irregularly irregular heart rhythm with persistent pulse deficits. The 12-lead surface ECG showed a third degree heart block. Permanent transvenous cardiac pacing with a bipolar implantable pacemaker was performed in the right ventricle. After pacemaker implantation, the dog did not show syncopal episode and is currently able to take a walk with an owner. No side effects associated with permanent pacemaker implantation has been observed to date.

  • A 9-year-old spayed female Shih-Tzu was presented with a mass on the upper eyelid of the right eye (OD). The eyelid mass continued to enlarge along the eyelid margin and the eyelid skin. Throughout the follow-up examinations, the mass did not affect the palpebral conjunctiva OD. Until 9 months since the mass was first identified, the dog did not show any clinical signs related to the mass. However, after 11 months, the owner complained of the dog's discomfort on OD and decided on surgical excision of the mass. There were no abnormalities in the complete blood count and serum chemistry profiles. The pentagonal resection was performed to completely remove the mass in the eyelid. There were no suspicious findings of metastasis on whole-body computed tomography scan immediately before the surgery. On histopathology and immunohistochemistry for multiple myeloma oncogene-1, the eyelid mass was diagnosed as extramedullary plasmacytoma (EMP). Surgical margin of the mass was clearly cut. No recurrence was observed during the 5-month follow-up. EMPs on the eyelid have rarely been reported in dogs. Although EMP is a benign tumor, the mass showed invasive growth and grew toward the skin rather than the palpebral conjunctiva. No recurrence occurred when surgically removed with clean margins.

  • A 6-year-old spayed female French Bulldog presented with a left-sided chest wall tumor. Physical examination revealed that the tumor was firmly adhered to the chest wall. A preoperative punch biopsy of the tumor revealed a grade 2 soft tissue sarcoma (STS). On computed tomography, the tumor's dimensions were assessed as 6.5 × 5.7 × 3.5 cm, and it exhibited invasiveness near the tissue surrounding the ninth rib. The tumor size was large in comparison to the dog's chest wall area. Hence, if the traditional wide-margin resection surgery were to be performed, primary wound closure seemed impractical and could potentially result in respiratory function complications. Therefore, considering the extent of tumor invasion and grade, deep margins were established to include the removal of the eighth to tenth ribs, and a 1-cm lateral margin was designated to enable primary wound closure. To reconstruct the chest wall, polypropylene mesh was attached to the adjacent ribs and the remaining muscles were sutured and covered over the mesh. The dog exhibited a rapid recovery beginning the day after the operation. Postoperative biopsy confirmed that the tumor was a grade 2 STS, and the surgical margins were evaluated as incomplete. The owner chose to pursue follow-up observation instead of chemotherapy. In this study, the surgical approach was chosen based on the importance of functional recovery after surgery. Recent research indicates that the tumor grade is more critical for postoperative prognosis than the extent of surgical margins when removing an STS.

  • This case report describes the increment of regulatory T cells in thyroid carcinoma of a mixed breed dog compared with normal dogs. A mixed breed dog was referred for a submandibular mass and hyperthermia. Right cervical mass was detected during the physical examination and radiography identified right cervical mass suspected thyroid gland. Accurate location and size of mass was confirmed using computed tomography and 3D reconstructed images. After confirmation of mass, surgical resection was performed and evaluation of regulatory T cells in blood of this patient was performed using flow cytometric assay. The percentage of regulatory T cells was 38.28% of all CD4 (+)/CD25 (+) T cells. This result was higher than median percentage of regulatory T cells of healthy 8 beagles ($7.66{\pm}1.65%$ (p<0.01) of all CD4 (+)/CD25 (+) T cells). And masses were confirmed as giant cell thyroid carcinoma based on histopathologic examination. After surgical resection of cervical mass was performed, the owner didn't want chemotherapy. Seven days later, cervical mass came out again. And CBC showed severe leukocytosis (WBC $47.6{\times}10^3/{\mu}L$) and non-regenerative anemia (PCV 21%). Suspected pulmonic metastasis regions became more severe. Finally the dog died of severe anemia and respiratory disorder.

  • An 8-year-old male dog weighing 7.9 kg was referred to us for evaluation of exophthalmos and corneal edema of the left eye, on which cataract surgery had been performed 3 years prior. On ophthalmic examination, the left eye showed an extremely high intraocular pressure (47 mmHg), with no menace response, dazzle reflex, or pupillary light reflex. The dog was treated with systemic and topical glaucoma medications. After treatment, corneal edema decreased but IOP did not return to within acceptable limits. Seventeen months later, the dog presented with hyphema, episcleral congestion, and corneal edema attributable to accidental trauma. The owner wished to maintain an attractive ocular appearance, and an intraocular silicone prosthesis (ISP) was thus inserted after the evisceration. Three months postoperatively, a corneal ulcer was detected, but this resolved successfully after prescription of appropriate medication. One year after surgery, no complications related to surgery were evident.
