隐睾是犬的常见病,分为腹股沟隐睾和腹腔隐睾。本文对3例犬腹腔隐睾进行了微创摘除和组织病理学观察。利用腹腔镜对犬进行腹腔探查,找到隐睾,并使用微创手术器械将隐睾摘除。术后3个病例均恢复良好。术后对隐睾样本进行组织病理学观察,结果显示均发生病变,3例隐睾的组织病理学诊断结果分别为睾丸支持细胞瘤、睾丸精原细胞瘤和慢性睾丸炎。结论:利用微创手术治疗犬腹腔隐睾具有创口小、出血少、术后恢复快等优点。由于腹腔隐睾发生病变的概率较高,应尽早手术摘除。 相似文献

睾丸肿瘤(Tumor of Testis,TOT)常见于犬,公犬发生睾丸肿瘤的几率很高,是犬类仅次于皮肤癌、位居第二的高发性肿瘤,有些品种如拳师犬、吉娃娃犬、波美拉尼亚犬、贵妇犬等易发。睾丸肿瘤是一个不太规范的形态学统称,病理学分类上通常包括精原细胞瘤、精母细胞瘤、睾丸间质细胞瘤和畸胎瘤等类型。睾丸肿瘤的发病率和恶变率随着公犬年龄的增大而升高,特别是高龄犬较常发, 相似文献

A 15-year-old crossbred dog was presented with a severe cough of acute onset and an enlarged right testis. Symptomatic treatment for presumed 'kennel cough' failed to produce any improvement and at re-examination the dog had developed a swollen right forelimb. Radiographic examination suggested a diagnosis of hypertrophic pulmonary osteoarthropathy (Marie's disease) associated with pulmonary metastases from a testicular tumour. The dog was re-presented five days later with acute-onset severe vomiting and the owner elected for euthanasia. Necropsy was performed and histopathological assessment confirmed the presence of a Sertoli cell tumour in the right testis with multiple pulmonary and renal metastases. Hypertrophic pulmonary osteoarthropathy is a rare complication of metastatic canine Sertoli cell tumour. The authors know of no previously reported cases. 相似文献

Abstract— The testes of the dog descend near the time of birth but little is known about the normal variability of this or about the retractability of the juvenile testis after descent. Therefore, it is difficult to give a firm diagnosis or prognosis when presented with a prepubertal dog in which one or both testes are not in the scrotum. Ectopic testis, displaced testis, anorchidism and monorchidism must also be considered in the diagnosis. 相似文献

Ultrasonography and nuclear imaging were used in the diagnosis of scrotal hernia in a dog. Both techniques were useful as aids in the differential diagnosis of scrotal enlargement. Nuclear imaging was useful in ruling out testicular torsion; ultrasonography revealed a normal-appearing testis amid fluid and portions of omentum. 相似文献

A bilateral testicular neoplasm from an 11-year-old mixed-breed male dog was removed surgically and examined histologically. The neoplasm was nonencapsulated and composed of acinar and tubular structures lined by one or more layers of neoplastic polyhedral epithelial cells with an abundant mucinous secretion. On histochemistry, all neoplastic cells and associated secretions were periodic acid-Schiff positive. Some neoplastic cells and all associated secretions were positive on mucicarmine stain, and some neoplastic cells, all the stroma, and associated secretions were positive on alcian blue stain. On immunohistochemistry, the neoplastic cells had strong diffuse cytoplasmic immunoreactivity for cytokeratin and vimentin, weak scattered cytoplasmic immunoreactivity for carcinoembryonic antigen and neuron-specific enolase, and no immunoreactivity for S-100. On the basis of histopathology, histochemistry, and immunohistochemical findings, a diagnosis of mucinous adenocarcinoma of rete testis was made. Rete testis adenocarcinoma is a well known but very rare neoplasm in humans. To our knowledge, this is the first report of the mucinous variant of adenocarcinoma of the rete testis in a dog. 相似文献

A 7-year-old male miniature schnauzer dog with unilateral cryptorchidism was presented for elective orchiectomy. Surgery to remove the cryptorchid testis revealed a fully formed uterus with horns attached to both testis and the body and cervix terminating at the prostate gland. The gross and microscopic diagnosis for the genital tract was persistent Müllerian duct syndrome with unilateral cryptorchidism. Additional associated lesions included cystic endometrial hyperplasia and a solitary, intratubular seminoma within the undescended testis. Persistent Müllerian duct syndrome is rare among domestic animals but is more common in miniature schnauzer dogs because of inheritance as an autosomal recessive trait. 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

An eight-week-old male puppy affected with trypanosomiasis and dumb rabies was presented at the University of Nigeria Veterinary Hospital. The dog had a septic wound on the side of the face. The clinical signs suggested trypanosomiasis and this diagnosis was confirmed by laboratory examination. After treatment with Berenil and antibiotics, the puppy apparently recovered, but a week later became anorectous and recumbent. Dumb rabies was suspected and the dog died in a quarantine kennel less than 24 hours later. Negri bodies were detected in brain smears from the dog and a mouse inoculation test was performed to confirm the diagnosis. Dumb rabies poses serious public health hazards to dog owners and their families, as well as to those occupationally exposed to dogs. 相似文献

The right testis and epididymis were excised from a Beagle dog that ejaculated high percentages of sperm with detached tails and with coiled tails. Cross sections of the organs were stamped on glass slides and histological examination of the organs was performed to find the portion where sperm with the abnormal tails appear. Many sperm with tails whose axoneme was exposed near the neck region were observed in the testis and they decreased in order from the caput, to the corpus, and the cauda epididymis. Sperm with detached tails and sperm with coiled tails gradually increased in the epididymis. These findings indicate that the tails of sperm with an exposed axoneme detached in the epididymis. 相似文献
