ABSTRACT: Tracheal stenosis, also known as “Honker syndrome”, is characterized by tracheal edema and hemorrhage, leading to partial obstruction of the lumen; therefore, death. Its etiology is not yet well elucidated. A 3-year-old Holstein cow, with a history of dyspnea, and a large amount of reddish foam flowing from the mouth and nose, had died after 10 minutes of clinical signs. Macroscopic examination revealed focally extensive hemorrhage and clot organization in tracheal mucosa extending to the submucosa, surrounded by well-differentiated fibrous connective tissue. In adjacent mucosa was observed moderate multifocal inflammatory infiltrate composed by lymphocytes and plasma cells, as well as moderate squamous cell metaplasia. The bacterial culture showed growth of contaminant and environmental bacteria and the RT-PCR to detect Herpesvirus 1 (BoHV-1) and 5 (BoHV-5) was negative. To the author’s knowledge, this is the first report of tracheal stenosis in South America, as well as the first report of this condition described in a Holstein cow.

Proximal Urethra

Congenital urethral strictures are well recognised in human beings and have recently been described in two cats but have not been previously reported in dogs. A 10-month-old female English Bull Terrier presented with a life-long history of being unable to pass a normal stream of urine. Urethrocystoscopy confirmed the presence of a stricture lesion in the proximal urethra. This thin, membranous structure was effaced under endoscopic visualisation using a 10 mm diameter balloon-dilation catheter. Complete and sustained resolution of clinical signs occurred after a single dilation procedure. To the best of our knowledge, this is the first report of a congenital urethral stricture in a dog and the term congenital obstructive proximal urethral membrane may be useful for describing these lesions in the future.

Macroscopic Examination

A 13-year-old female spayed Domestic Shorthair cat presented with a history of right-sided mucopurulent nasal discharge for 18 months. Computed tomography revealed a mass within the right nasal cavity and the right frontal sinus. The animal was euthanized, and a postmortem examination was performed. On macroscopic examination, the right nasal cavity and the right frontal sinus were partially occluded by a soft whitish mass. Microscopically, the mass was composed of well-differentiated plasma cells that were immunopositive for immunoglobulin G and lambda light chains. These findings were consistent with a mature-type sinonasal plasmacytoma. In addition, there was right-sided mucopurulent rhinitis and sinusitis caused by a Pasteurella infection, which probably developed secondary to the sinonasal plasmacytoma. To the authors’ knowledge, this is the first report of a sinonasal plasmacytoma in a cat. The present communication shows that feline sinonasal plasmacytomas should be included in the differential diagnosis for tumors located in the upper respiratory tract of cats.

The Masses

An 18-month-old, spayed female Australian terrier cross was presented with a 10-month history of chronic large bowel diarrhea. Ulceration and two proliferative masses in the rectum were seen on colonoscopy. Surgical resection was performed to remove the masses, and the dog recovered without complications related to surgery. Histopathology was consistent with the diagnosis of ganglioneuroma. The dog had no clinical signs of disease within three months of surgery and was completely normal 2.5 years after diagnosis. This is the first report providing follow-up and successful outcome of a ganglioneuroma in the gastrointestinal tract of a dog.

ABSTRACT The aim of this report is to describe a case of marked osseous metaplasia in the placenta associated with abortion in a mare. A 19-year-old Campolina mare with a history of multiple parturitions and absence of reproductive failure, aborted a fetus with approximately six months of gestation. There were no gross changes in the fetus and the placenta. Microscopically, there was multifocal replacement of fetal connective mesenchyme of the chorionic villi with well differentiated and partially mineralized osseous tissue (confirmed by von Kossa staining). To further characterize the collagenous component of the lesion, sections of the placenta were stained with Masson’s trichrome and Picrosirius red. Osseous tissue deposition had abundance of type I collagen. To the best of our knowledge, this is the first report of osseous metaplasia in the placenta of a mare associated with abortion at mid gestation, presumably due to placentary insufficiency.

SummaryTransient Fanconi syndrome without azotemia was diagnosed in a dog and was associated with ingestion of Chinese chicken jerky treats. Fanconi syndrome is a proximal renal tubular defect and a diagnosis was made based upon severe glucosuria with normoglycemia, and severe generalized aminoaciduria. The clinical signs of polyuria and polydipsia as well as the massive urinary metabolic abnormalities resolved after jerky treat withdrawal. While frequently seen in North America and Australia, this is the first report of jerky treat induced Fanconi syndrome in continental Europe. Clinicians should be aware of this potential intoxication and be vigilant for a history of jerky treat consumption in a dog with glucosuria.

An 11-year-old cat with a retained testis was presented with a chronic history of dysuria and bladder atony. Medical therapy failed to alleviate the clinical signs. Contrast radiography demonstrated a diffusely narrowed urethra. During a celiotomy and prepubic urethrostomy, a retained testis, stenosed urethra, and irregularly enlarged prostate were observed. Histopathologic diagnosis was retained testis with a well-differentiated interstitial cell tumor, a poorly differentiated interstitial cell tumor, and marked squamous metaplasia of the prostatic epithelium with suppurative prostatitis. Neoplastic interstitial cells were immunoreactive for Melan A, consistent with reports of Melan A expression in steroid hormone-producing tissue. This is the first report of prostatic squamous metaplasia associated with testicular neoplasia in a felid.

A four-year-old female entire Weimaraner, recently diagnosed with epilepsy, was referred with a three-week history of coughing and lethargy. The dog had been diagnosed with aspiration pneumonia on thoracic radiographs, but the cough continued despite antibiotic therapy and an apparent improvement in the radiographic lung changes. CT of the thorax revealed a diffuse and severe nodular thickening of the tracheal wall. Tracheoscopy showed a thickened and irregular mucosa with multiple nodules causing segmental stenosis of the trachea. Histopathology of the nodular tracheal mucosa demonstrated severe, multifocal to diffuse neutrophilic inflammation. Once infectious and neoplastic causes were excluded, the dog was diagnosed with an inflammatory tracheitis of unknown aetiology. A tapering course of glucocorticoids was prescribed, which led to a complete clinical and endoscopic resolution of the coughing and tracheal lesions, respectively.

The gross and histopathologic lesions of meningoencephalitis tuberculosa in a 4-year-old Holstein cow showing clinical signs compatible with bovine spongiform encephalopathy are described in this report. Grossly, numerous gray to yellow, firm and caseous nodules were seen on the ventral surfaces of the brain and in the lateral and fourth ventricles. Histopathologically, foci of caseation and dystrophic mineralization were surrounded by multinucleated giant cells, epitheloid macrophages, plasma cells, lymphocytes and fibrous proliferation. Ziehl-Neelsen stains of the lesions revealed masses of slender acid-fast bacilli in the necrotic centers of lesions and within surrounding giant cells.

An 11-year-old, neutered, male domestic shorthair was presented with a five-month history of recurrent, unilateral, seromucoid discharge from the right eye. A verrucous mass extended from the posterior aspect of the nictitating membrane. Adenocarcinoma of the gland of the nictitating membrane (GNM) was diagnosed upon biopsy. The cat subsequently developed metastases to the lungs, pleura, mediastinum, liver, and kidneys and died six months after clinical signs first were observed. Little is known about the biological behavior of adenocarcinoma of the GNM in cats. This is the first report that describes the natural progression of this disease.

A 6-month-old male domestic shorthair cat was presented for a 3-month history of dysphagia and upper respiratory signs. The cat was diagnosed with a generalized megaesophagus secondary to a large nasopharyngeal polyp that extended into the cervical esophagus. The polyp was removed by traction and a left ventral bulla osteotomy was performed to remove the polyp base. The cat's clinical signs resolved and follow-up radiographs 14 days after surgery revealed resolution of the megaesophagus. To the authors' knowledge, this is the first report of resolution of megaesophagus after removal of a nasopharyngeal polyp in a cat.
