Objective: To describe a unique case of pyometra with inguinal herniation of the left uterine horn and omentum. Case summary: A 7‐year‐old, 19 kg, intact female Beagle dog presented for surgical treatment of presumptive pyometra and biopsy of a caudal abdominal mass in the left inguinal mammary gland region. Ventral midline celiotomy was performed, and a distended, fluid‐filled uterus with passage of the distal aspect of the left uterine horn through the left vaginal process into the inguinal canal was identified. The patient recovered uneventfully following ovariohysterectomy and left inguinal herniorrhaphy. New or unique information provided: This is the first documented report of inguinal herniation of a uterine horn associated with a pyometra.  相似文献

A six-year-old, pluriparous German shepherd dog bitch was presented with an abnormal vaginal discharge of several weeks' duration. Clinical signs and radiographic and ultrasonographic findings supported an initial diagnosis of segmental cystic endometrial hyperplasia, and ovariohysterectomy was performed. Macroscopic-ally, the uterus appeared normal except for one large and several smaller cysts attached to its antimesometrial side. These cysts were restricted to a small area of the left uterine horn. The histological diagnosis was serosal inclusion cysts. The clinical findings, gross pathology and histopathology are described and discussed.  相似文献

A 1.5-year-old female Persian cat was presented for inappetence and azotemia. Ultrasonography and urography revealed multiple abnormalities involving the genitourinary tract, including agenesis of the right kidney and ureter. Gross examination of the abnormal uterus revealed segmental aplasia of right caudal uterine horn causing cranial distension with fluid, a normal left uterine horn, and both normal ovaries. Microscopically, endometrial glands of the right uterine horn were markedly decreased in number. The right uterine horn was hemorrhagic suggesting estrus. This is the first report of this combination of urinary and uterus abnormalities in the veterinary literature.  相似文献

A 6-year-old female Alaska Malamute dog was presented for evaluation of abdominal enlargement referred by a local veterinarian. On the history, the owner complained of chronic abdominal enlargement initiated more than 4 months ago, reduced appetite, occasional vomiting and general dullness. He also complained of greenish mucous intermittent vaginal discharge starting 10 days ago. The bitch was chronically treated with medroxiprogesterone acetate. A laparatomy was performed and fluid in the abdomen was found and aspirated during the surgery. Also a very fluid-filled distended uterus and a mass in the distal part of the left uterine horn were found. The mass was encapsulated by the omentum, but areas of necrosis and calcification were identified. Histopathological diagnosis was endometrial adenocarcinoma.  相似文献

Uterine torsion secondary to sacculation of the uterine horns was diagnosed in two non-gravid bitches which were presented with anorexia, polydipsia and an acutely swollen abdomen. On the basis of the radiological and ultrasonographic findings, which indicated the presence of an enlarged spherical or tubular structure filled with hypoechoic material in the caudal abdomen, a tentative diagnosis of pyometra was made. Exploratory laparotomy revealed unilateral uterine horn torsion along the longitudinal axis, with bilateral fluid-filled sacculations. Ovariohysterectomy was performed in both cases. Pathological examination of the uteri demonstrated haematometra in one dog and pyometra in the other.  相似文献

OBJECTIVE: To compare the bursting strength of a vessel sealant device (VSD) with that of an encircling suture on uterine horns and bodies from dogs. SAMPLE: Uteri from 24 shelter dogs with unknown reproductive histories. PROCEDURES-Uterine horns and bodies were allocated to groups to be sealed with suture or a VSD. Uteri were then infused with saline (0.9% NaCl) solution until the seals burst or the uteri reached a maximal pressure of 300 mm Hg. Variables recorded included dog age, uterine body and horn diameter, and maximal pressure. RESULTS-The median (range) bursting pressure reached in sealed uterine horns was 300 (0 to 300) mm Hg for the VSD group and 300 (200 to 300) mm Hg for the suture group. Within the VSD group, seals of 2 of 3 uterine horns with a diameter ≥ 9 mm burst before intraluminal pressure reached 100 mm Hg, compared with 1 of 21 uterine horns with a diameter < 9 mm. The median bursting pressure for uterine bodies was 237 (0 to 300) mm Hg for the VSD group versus 300 (175 to 300) mm Hg for the suture group. Within the VSD group, seals in uterine bodies with a diameter ≥ 9 mm failed at a significantly lower pressure (125 [0 to 125]) mm Hg than those with a diameter < 9 mm (275 [125 to 300]) mm Hg. CONCLUSIONS AND CLINICAL RELEVANCE-The failure pressure for both sealing techniques was high, which indicated that the VSD may be a safe instrument for sealing the uterine horn in dogs. Given the low mean bursting pressure for seals in uterine bodies with large diameters, the VSD cannot be recommended for sealing uterine bodies ≥ 9 mm in diameter.  相似文献

Bilateral segmental aplasia of the uterine horns with unilateral pyometra and uterine horn torsion were diagnosed in a Pomeranian bitch that presented with chronic abdominal distension and an acute onset of anorexia and lethargy. Because radiographic and ultrasonographic findings revealed the presence of markedly enlarged bilateral uterine horns filled with fluid in the caudal abdomen, a tentative diagnosis of either pyometra or hydrometra with uterine horn torsion was made. Exploratory laparotomy showed bilateral, segmentally distended uterine horns with unilateral uterine horn torsion. Ovariohysterectomy was performed, and bilateral segmental aplasia of the uterine horns with the development of unilateral uterine horn torsion was diagnosed histopathologically. To the authors' knowledge, this is the first report of uterine horn torsion in conjunction with segmental aplasia of the uterine horn in a bitch.  相似文献

Congenital urethral sphincter mechanism incompetence is a cause of urinary incontinence in female dogs and cats. In some of these animals, urethra hypoplasia is the primary diagnosis, with the urethra being almost absent in some patients. Treatment of this problem can be difficult. This paper describes two techniques for the surgical treatment of eight cats and one dog with severe urethral hypoplasia. In five animals, partial excision of the bladder neck was performed to create a longer "urethra." In the other four, an attempt was made to conserve bladder volume while simultaneously creating a urethra with a bladder neck flap reconstruction technique. One cat was lost to follow-up, but the clinical signs resolved in three cats and the remaining animals improved. Two cats had recurring cystitis, possibly associated with bladder neck diverticula because of uterine horn remnants terminating abnormally in the bladder. The results in this limited series suggest that reconstructive surgery in cases of severe urethral hypoplasia improves continence control.  相似文献

A 4-year-old, neutered female Cocker Spaniel was presented to the veterinary clinic for protrusion of the left third eyelid. When the third eyelids from both eyes were everted, lobulated masses were present on the bulbar surface. The left third eyelid had a larger protrusion. There was no apparent associated ocular or systemic involvement. The tumor of left third eyelid was removed and referred for histological examination. Histologically, there were proliferations of lymphoid follicles surrounded by lymphoid cells forming a marginal zone. Those lymphoid cells occasionally infiltrated into conjunctival epithelium. A few apoptotic bodies with karyopyknotic and karyorrhexic nuclei were observed in the germinal center of lymphoid follicles. Mitotic figures were rare. On immunohistochemistry, tumor cells expressed CD79a but not CD3. A diagnosis of extranodal marginal zone B-cell lymphoma of mucosa-associated lymphoid tissue (MALT) of the third eyelid was established based on the histological and immunophenotypical features. At the 1-year follow-up, there was no evidence of recurrence of the mass at the area of excision of the left third eyelid and the remaining tumor of the right third eyelid was still a similar size. The dog still showed no significant findings, except those of the tumor, and no evidence of systemic involvement. To the authors' knowledge, this is the first reported case of MALT lymphoma of the third eyelid in a dog.  相似文献

Primary (extranodal) malignant lymphoma limited exclusively to the urinary bladder is an extremely rare disorder in both humans and animals and has to be differentiated from malignant lymphoma cases where a systemic (multicentric) lymphoma has spread to the bladder. We report a case of a 3-year old female spayed mixed breed dog presenting with gross haematuria and dysuria and diagnosed with a primary B-cell high-grade lymphoma of the urinary bladder without involvement of any other site. After treatment with a combination of hypofractionated external beam radiation and cytotoxic chemotherapy, rapid and complete remission of the tumor occurred. At present the dog is alive and has been in remission for 52 months.  相似文献

Purpose Canine lymphoma (CL) is one of the most common forms of spontaneous canine neoplasia. Improved understanding of the genetic and environmental factors associated with CL may provide benefits for the study of non‐Hodgkin’s and Hodgkin’s lymphoma in humans. Uveodermatologic lymphoma is reported in a single household of Portuguese water dog, and the etiology is discussed. Methods A 1‐year‐old female intact Portuguese water dog was referred to the Ophthalmology Service of the Veterinary Teaching Hospital of the Autonomous University of Barcelona because of acute blepharospasm of the right eye in association with a multinodular dermatosis. Physical and ophthalmological examination and a complete diagnostic work‐up, including skin and ocular histopathology and immunohistochemistry, were performed. Three months prior, in Galicia (Spain), 1200 km away from Barcelona, a male dog of the same litter showed very similar oculodermatological clinical signs and skin histopathology, and immunohistochemistry were obtained. Results The clinical diagnoses were anterior exudative uveitis, iridal masses, and secondary glaucoma. Histopathology and immunohistochemistry revealed a nonepitheliotropic lymphoma rich in B cell in dog 1 and rich in T cell in dog 2. Conclusion It is proposed that an underlying genetic predisposition could have played a role in the development of lymphoma in these two young related dogs.  相似文献

A case of intersexuality in a Pug that was bought as a male in a pet shop is described. The dog was presented at the Veterinary Teaching Hospital, University of Turin, for a reddish mass protruding from the prepuce. The mass had the aspect of an enlarged clitoris, with a caudoventral direction and a dorsal urethral ostium. A gonad was palpable in the left inguinal region. Laparotomy confirmed ultrasound detection of an abdominal uterine structure together with the right gonad. The histology of both gonads was similar, showing an exclusively masculine character, with seminiferous tubules lined only by Sertoli cells; the uterus showed a normal histological structure. Karyological analysis revealed a female karyotype (78,XX), and polymerase chain reaction showed the absence of Sry. The diagnosis was an XX male. The pathogenesis of the XX sex reversal syndrome in dogs is not completely understood, as Sry, the master gene regulating testis differentiation, is not present; to date, no genetic cause has been identified for this phenotypic condition in dogs. This case is unusual because the dog showed an inguinal testis, implying a partial activity of the mechanisms leading to abdominal testis translocation along a gubernaculum and transinguinal migration.  相似文献

A 10-year-old female Cavalier King Charles Spaniel presented with hematuria, pollakiuria and skin rash. Based on the histopathological and cytological examination of the skin and bladder mucosa, the dog was diagnosed with large granular lymphocytic (LGL) lymphoma of the bladder and skin. The dog responded well to the initial chemotherapy with nimustine for 3 months. Since recurrence of skin erosion and bladder wall thickening were observed, the dog was subsequently administered chemotherapy with other anticancer drugs, including chlorambucil, vincristine, doxorubicin, L-asparaginase, cytosine arabinoside, and cyclophosphamide. The dog survived for 11 months and died due to tumor-related disseminated intravascular coagulation. This is the first report of a canine case of LGL lymphoma in the skin and bladder.  相似文献

The fertility was compared between ejaculated and cauda epididymal sperm sensitized with prostatic fluid in dog after freeze-thawing using the fertility of ova from the contralateral ovary after injection (2 × 10(8) sperm) into dog uterus on the unilateral ovariectomized side, on the basis of the presence or absence of conception. No significant difference was observed in sperm quality after freeze-thawing between the two groups and conception rates were equivalent and low. Therefore, to achieve a high fertility by intrauterine insemination of canine frozen-thawed ejaculated and cauda epididymal sperm, intrauterine insemination on both sides is recommended, rather than insemination with a lot of sperm of the uterine horn on one side.  相似文献

The reproductive tract of the female is a part of the mucosal system which protects from pathogens invasion. We have analysed the presence and distribution of total lymphocytes, plasma cells (antibody secreting B cells) and T lymphocytes subsets in the reproductive tract of the female goat. The influence of the oestrous cycle on the densities of lymphocytes and plasma cells of the cervix and uterus horn was evaluated in sections prepared for conventional histology. Immunocytochemistry was used for the study of lymphocyte subsets by confocal microscopy and immunoperoxidase techniques. Present results show that the reproductive tract of the goat is a site rich in lymphocytes. These cells were found mingled with the epithelial cells of the endometrium and distributed throughout the stroma. Lymphocyte aggregates were observed in the stroma. Lymphocyte but not plasma cell number changed depending on the reproductive stage of the goats. The impact of the hormonal environment was different for the cervix and uterine horn. Immunocytochemistry studies evidenced the presence of cells displaying immunoreactivity for both CD 4+ and CD 8+ antibodies in the epithelial layer and stroma of the cervix and uterine horn. These cells were more numerous in the cervix and were also found infiltrating the luminal epithelia of endometrial glands. Overall, our results indicate that lymphocyte distribution is different in the cervix and the horn, and is influenced by the stage of the reproductive cycle. In summary, CD 4+ and CD 8+ T lymphocytes subsets could be found in the endometrium of both the cervix and uterine horn of the goat reproductive tract.  相似文献

A two-year-old, neutered female cross-bred labrador had multiple cutaneous nodules, biopsies of which revealed pathological changes consistent with cutaneous histiocytosis. During a period of one month the dog developed multicentric lymphadenopathy, a retrobulbar mass and masses within the quadriceps and cervical muscles. Fine needle aspiration cytology of the cutaneous nodules and lymph nodes and histological examination of the cutaneous nodules and muscle masses suggested the presence of lymphoblastic lymphoma. A definitive diagnosis of CD8+ T cell lymphoma was achieved by immunophenotyping the tumour cells by flow cytometry.  相似文献

One month after ovariohysterectomy, a 2-year-old spayed female Golden Retriever was evaluated because of an extensive uterine stump abscess. Clinical signs included intermittent vomiting, signs of depression, lethargy, and pollakiuria. The dog underwent abdominal surgery; the greatly enlarged uterine stump was tightly adhered to the dorsal surface of the bladder, encompassing the distal portions of the ureters and the bladder's neurovascular supply. En bloc resection of the uterine stump was not considered an acceptable treatment option because of the risk of surgical damage to and subsequent devitalization of the bladder or ureters, urinary incontinence, or urinary tract obstruction. Therefore, the diseased uterine tissue that extended cranial to the bladder was resected, and the remaining abscess cavity was lavaged and packed with omentum. The dog recovered fully from the procedure. The omentum is an effective physiologic drain; its extensive vascular and lymphatic networks absorb fluid and actively promote elimination of infection. Omentalization appears to be an option for surgical management of nonresectable uterine stump abscesses in dogs.  相似文献

A 16‐year‐old, spayed, female poodle dog was presented for evaluation of tenesmus, with the ability to attract male dogs and a willingness to mate. The dog had undergone an ovariohysterectomy when it was 7 years old. Haematological and serum biochemistry analyses demonstrated leucocytosis and a mild uraemia. A vaginal smear was predominantly made up of superficial cells, accounting for at least 80% of the cells. Abdominal ultrasonography revealed a heterogeneous multicystic mass at the caudal abdomen and two masses with anechoic areas adjacent to the caudal pole of each kidney. A midline exploratory laparotomy identified a uterine mass and residual ovaries that were surgically excised. Histopathological examination of the mass demonstrated that it was a leiomyoma. The left ovary had a cystic structure and the right ovary had a papillary cystic adenoma. Seven months after the surgery, the owner reported that the dog was clinically normal. To the authors’ knowledge, this is the first reported case of a uterine leiomyoma after an incomplete ovariohysterectomy in the dog.  相似文献
