An eight-year-old female German wirehaired pointer was presented with signs of respiratory distress. Clinical examination, laboratory results, thoracic radiography and echocardiography indicated the presence of a diffuse interstitial lung disease with secondary appropriate erythrocytosis, pulmonary hypertension and cor pulmonale. Transthoracic fine needle aspiration biopsy of the lung suggested malignant epithelial neoplasia. A primary lung cancer with an unusually diffuse distribution of miliary/micronodular lesions was found at postmortem examination. Histological diagnosis was bronchiolo-alveolar carcinoma. Bronchiolo-alveolar carcinoma can occasionally occur in a diffuse fashion involving most or all of the lung parenchyma. In man, diffuse bronchiolo-alveolar carcinoma is considered a great imitator of other, more common diffuse interstitial forms of lung disease. This case report indicates that it is also a differential diagnosis to consider in dogs. 相似文献

Fine needle aspiration biopsy is a fast and inexpensive technique well tolerated by animals. Its efficacy for the diagnosis of malignancy and determination of cellular origin was investigated for 97 malignant tumors and five benign lesions in 83 dogs and 19 cats. Histological examination of the lesions was performed in each case. Malignancy was detected by cytology in 69% of the malignant tumors. The cellular origin of the lesion was determined in 74% of the cases. Confirmation of malignancy and determination of cellular origin permitted an early diagnosis and prognosis. Since fine needle aspiration biopsy and cytology cannot definitely rule out malignancy, a surgical biopsy and histopathology should be done when malignancy is suspected clinically and not confirmed cytologically. Specimens of good quality, adequate collaboration between the cytologist and clinicians, and sufficient knowledge of pathology and cytology are basic requirements for obtaining good results with fine needle aspiration biopsy and cytology. 相似文献

Abstract: An 8‐year‐old, spayed female Labrador Retriever was presented for evaluation of unwillingness to exercise. On clinical examination abdominal pain was elicited, and a midabdominal mass was detected in survey radiographs. Ultrasound‐guided fine‐needle aspiration of the intra‐abdominal mass was done. The cytologic findings indicated chronic granulomatous inflammation with reactive fibroplasia, cholesterol crystals, and extracellular foreign material. The foreign material consisted of opaque, basophilic fragments of uniform width (5–10 μm) and variable length (30–180 μm) and was observed extracellularly and within macrophages. The material was birefringent under polarized light. Histologic examination of the excised mass confirmed the cytologic findings and a diagnosis of gossypiboma (textiloma) was made, consistent with retention of a surgical sponge. This case provides a unique example of the utility of fine‐needle aspiration for the diagnosis of gossypiboma. 相似文献

Transitional cell carcinoma (TCC) of the renal pelvis was found in two dogs, a 7-year-old male English Setter and a 11-year-old female Shetland shepherd. Affected dogs were presented for clinical examination without any specific symptoms but haematuria in case 1 and occurrence of whitish material in the urine of case 2; neoplastic disorders were discovered with ultrasonographic investigation and fine needle aspiration biopsy. Histopathological examination was carried out after nephrectomy and ureterectomy of the affected kidney of both dogs, and confirmed the diagnosis of non-invasive and low grade TCC in case 1 and of infiltrating TCC in case 2. The clinical, gross, cytological and histopathological features of these rare tumours originating from transitional epithelium of the renal pelvis are reported. 相似文献

Two dogs were examined for hypersialism associated with non-painful, symmetrical enlargement of both mandibular salivary glands. These signs were accompanied by inappetence and weight loss. The underlying cause of the problem could not be determined despite extensive investigations including fine needle aspiration biopsy of affected salivary glands. Hypersialism and mandibular salivary gland enlargement resolved completely during pheno-barbitone administration. 相似文献

A retrospective study was performed to report the histologic examination results of regional lymph nodes of dogs and cats with oral or maxillofacial neoplasms. Twenty-eight dogs and 3 cats were evaluated. Histologic examination results of standard and serial tissue sectioning of regional lymph nodes were recorded. When available, other clinical parameters including mandibular lymph node palpation, thoracic radiographs, and pre- and postoperative fine needle aspiration of lymph nodes were compared with the histologic results. Squamous cell carcinoma, fibrosarcoma, and melanoma were the most common neoplasms diagnosed in dogs. Squamous cell carcinoma and fibrosarcoma were diagnosed in cats. Of the palpably enlarged mandibular lymph nodes, 17.0% had metastatic disease histologically. Radiographically evident thoracic metastatic disease was present in 7.4% of cases. Preoperative cytologic evaluation of the mandibular lymph node based on fine needle aspiration concurred with the histologic results in 90.5% of lymph nodes examined. Postoperative cytologic evaluation of fine needle aspirates of regional lymph nodes concurred with the histologic results in 80.6% of lymph nodes examined. Only 54.5% of cases with metastatic disease to regional lymph nodes had metastasis that included the mandibular lymph node. Serial lymph node sectioning provided additional information or metastasis detection. Cytologic evaluation of the mandibular lymph node correlates positively with histology, however results may fail to indicate the presence of regional metastasis. Assessment of all regional lymph nodes in dogs and cats with oral or maxillofacial neoplasms will detect more metastatic disease than assessing the mandibular lymph node only. 相似文献

Ultrasound-guided fine needle aspiration was used in establishing the diagnosis in 4 cases of malignant peripheral nerve sheath tumor. Sonographic and cytologic characteristics are discussed. Because of its availability and ease of use, axillary ultrasonography with fine needle aspiration can be an initial diagnostic step for suspected brachial plexus tumors. 相似文献

Percutaneous fine needle aspiration biopsy (FNAB) was used to diagnose a urinary bladder carcinoma in an aged cat. The cytologic appearance of specimens collected initially was similar to that reported for canine transitional cell carcinoma. However, impression smears of the tumor made at necropsy 7 weeks later consisted predominantly of atypical squamous epithelial cells compatible with squamous cell carcinoma. Histologically, the malignancy was noted to have intermixed areas of abnormal squamous and transitional cell proliferation. The neoplasia was interpreted as a transitional cell carcinoma with extensive transformation to squamous cell carcinoma. This report examines the use and limitations of FNAB in the diagnosis of feline urinary bladder carcinoma and the incidence and behavior of these tumors in the cat. 相似文献

Objective
To evaluate the safety of fine‐needle aspiration of adrenal gland lesions in dogs and to characterise the risks in a subset of patients with cytologically or histopathologically diagnosed phaeochromocytoma.Materials and Methods
Retrospective review of medical records of dogs that underwent percutaneous ultrasound‐guided fine‐needle aspiration of adrenal gland lesions between August 2014 and December 2016. Nineteen dogs were identified, with three undergoing bilateral adrenal gland aspiration and one dog undergoing aspiration twice, yielding 23 cytology samples in total. Data collected included signalment, concurrent medical conditions, current medications, blood pressure and heart rate before adrenal fine‐needle aspiration, imaging characteristics of the adrenal gland lesions and any clinically apparent procedure‐related complications.Results
Phaeochromocytoma was diagnosed in nine of 19 dogs, including one dog with bilateral phaeochromocytoma. One dog developed ventricular tachycardia following aspiration of an adrenal gland lesion cytologically consistent with a phaeochromocytoma.Clinical Significance
Percutaneous ultrasound‐guided fine‐needle aspiration of adrenal gland lesions appears to be relatively safe, even in phaeochromocytoma, but further data are required to lend more weight to this finding. Minimally invasive aspirates could be considered as part of the diagnostic algorithm in the investigation of an incidentally detected adrenal gland lesion of uncertain clinical significance. 相似文献11.

Cytological smears and histological sections collected from histologically diagnosed cases of thymoma in nine dogs and four cats were reviewed. Most of the histological features were apparent in the cytological specimens with two notable differences. The epithelial component was underestimated and Hassal's corpuscles were not observed using Wright's-stained cytological preparations. Features of thymoma were recognized in seven of the nine cases in which fine needle aspiration biopsy was done. Therefore, cytology, and specifically fine needle aspiration biopsy, has the potential to be a useful aid in the rapid diagnosis of canine and feline thymomas. 相似文献

A case of bilateral, upper urinary tract infection caused by haemolytic E coli in a female Birman cat is presented. Ultrasonographic examination of the kidneys documented changes in size, outline, echogenicity and architecture. Ultrasound guided fine needle aspiration of fluid from the renal pelvis was used to make the diagnosis. Fluid was submitted for culture and sensitivity and based on the results, antimicrobial therapy was initiated. The treatment was monitored over a 406-day follow-up period. Despite extensive treatment with specific antibiotics and supportive therapy, recurrence of urinary tract infection occurred. 相似文献

Fine needle aspiration of abdominal organs: a review of current recommendations for achieving a diagnostic sample 下载免费PDF全文
下载免费PDF全文 With the improved accessibility to ultrasound, fine needle aspiration of abdominal organs is now performed frequently in many veterinary practices. Despite this, there are many ‘unknowns’ as to the best method to produce a high‐quality sample. This report begins by highlighting recent literature on the risks and benefits of abdominal fine needle aspiration. It follows with recommendations about the equipment and method best suited to the procedure, including needle and syringe size and aspiration versus non‐aspiration techniques. Various smear preparations and laboratory submission requirements are also discussed. The final aspect of the review more specifically discusses fine needle aspiration of specific abdominal organs: the liver, kidney, spleen, pancreas, urinary bladder, prostate and abdominal lymph nodes. 相似文献

A seven-year-old female German shepherd dog was presented with a history of anorexia, weight loss and fever of three months' duration. On general examination she showed a marked behavioural change represented by episodic excitement and 'fly snapping. A general blood screening showed neutrophilia with left shift and hyperalbuminaemia. Survey radiographs were taken and a mass was identified in the cranial mediastinum. Cytological examination of fine needle aspiration smears of the mass yielded a presumptive diagnosis of lymphoma. The dog was euthanased and necropsy findings concluded that the primary tumour was a thymoma; metastases were found in the choroid plexus, leptomeninges, cerebral cortex and hippocampus. 相似文献

Vulvovaginectomy and neo-urethrostomy were performed in a 9-year-old German shepherd dog following a diagnosis of infiltrative vulvar and vestibulovaginal haemangiosarcoma. The dog was presented for intermittent vulvar haemorrhage over a 3-month period. On examination the vulva and vestibulovagina were distended and firm. Vaginal discharge and fine needle aspiration cytology detected anaplastic cells. Haemangiosarcoma was diagnosed on biopsy. A new urethral opening was created in the floor of the vagina allowing resection of the vulva and caudal vestibulovagina. Urinary continence was preserved and healing was without complications. 相似文献

The results of testicular aspirate cytology taken from clinical patients with a history of infertility were compared with the clinical and histological findings. Azoospermia was the most common and the most rewarding indication for the examination. Samples were also taken from cases with suspected testicular tumours, orchitis, epididymitis, severe oligo- and teratozoospermia, lack of libido and unilateral testicular atrophy. Histological and cytological findings were found to correlate well. Identification of cell types from normal germinal epithelium was relatively easy. No Immediate adverse effects of aspiration were noted. Five normospermic dogs were monitored for two to six months after aspiration, and there were no marked deleterious effects on testicular consistency, testicular histology or semen characteristics. Testicular cytology obtained by fine needle aspiration may, at least to some extent, be used to assist clinical diagnosis, especially In azoospermlc dogs and dogs with palpable changes of testicular tissue. 相似文献

The simultaneous occurrence of bronchiolar-alveolar carcinoma and large cell anaplastic carcinoma of the lung is reported in a 12-year-old Australian terrier. Radiological findings in this case indicated diffuse infiltration but were nonspecific. Cytological examination of a fine needle lung aspirate and post mortem examination confirmed the presence of two concurrent forms of pulmonary neoplasia. 相似文献

A 13-year-old, intact male, golden retriever was presented for glossomegaly. A diagnosis of a caudal lingual abscess was made by fine needle aspiration under general anesthesia. The dog showed marked clinical improvement following abscess drainage. Lingual abscesses should be included as a differential diagnosis in any dog with an unexplained acute glossomegaly. 相似文献

An 11-year-old, female, spayed caracal (Caracal caracal) presented with a 3-month history of intermittent anorexia, vomiting, and weight loss. At examination, bilateral anterior uveitis with anisocoria was present. Further examination under general anesthesia revealed the anterior chamber of the right eye contained copious amounts of thick fibrin, hypopyon, and hyphema obscuring the ventral pupil margin and ventral iris. Aqueous paracentesis revealed a cytologic diagnosis of large granular lymphoma. Additional antemortem diagnostics (computed tomography, ultrasound with fine needle aspiration, and cytology) confirmed the diagnosis of multicentric large granular lymphoma with associated intestinal perforation. Necropsy and histopathology confirmed multicentric large granular lymphoma in the right eye, jejunum, mesenteric lymph nodes, and right kidney. Large granular lymphoma in nondomestic felids is likely rare since it has not been previously reported, but should be considered as a differential in any felid species with anterior uveitis or when lymphoma is considered. In the case of this caracal, the use of aqueous paracentesis with cytology was a powerful diagnostic. 相似文献
