Canine transmissible venereal tumor (TVT) is a round cell neoplasm occurring on the external genital mucosa of male and female dogs. Transmission is by cell implantation during coitus, licking, or other interaction between an affected dog and a susceptible host. Metastasis of the tumor rarely occurs. This report describes an unusual presentation of TVT with intraocular involvement and inguinal lymph nodes metastasis. The subject was a six-year-old, intact, male, Brazilian Terrier dog with a history of abnormal masses in the right eye, penis and several subcutaneous nodules in the inguinal area. Histopathological examination of the eye specimens as well as cytologic examination of penile mass and subcutaneous nodules revealed similar findings. The examination revealed round cells containing a large nuclei with prominent, central located nucleoli and a pale cytoplasm containing few small, clear round vacuoles. Histologically, the subcutaneous nodules in the inguinal area were lymph nodes. The diagnosis of TVT with intraocular involvement and lymph nodes metastasis was based on clinical, cytologic and histopathologic findings.

Purpose: To describe a rare presentation of a case of intraocular non-teratoid medulloepithelioma with teratoid metastases in ipsilateral intraparotid lymph nodes. Case description: A 9-year-old male child with previous history of ciliary body non-teratoid medulloepithelioma presented with a swelling in the right pre-auricular region for 1 month. Magnetic resonance imaging and positron emission tomography–computed tomography showed a right intraparotid mass with enlarged ipsilateral cervical lymph nodes. A core biopsy was taken from the lesion, which on microscopy showed a tumor composed of small round cells arranged in cords, tubules lined by multilayered cells, and in cribriform pattern. These cells were embedded in a hypocellular, loose myxoid matrix. Based on the histopathological characteristics and previous history, a diagnosis of medulloepithelioma metastastic to ipsilateral parotid gland was made. The patient underwent right total conservative parotidectomy and bilateral neck dissection. Histopathological examination revealed metastatic medulloepithelioma in five out of eight intraparotid lymph nodes, with extranodal extension into the adjacent parotid parenchyma. Foci of hyaline cartilage were identified within the tumor, leading to a diagnosis of metastatic teratoid medulloepithelioma. Conclusion: Intraparotid lymph node metastases from intraocular medulloepithelioma is a rare possibility and we recommend that the parotid should be evaluated in cases of intraocular medulloepithelioma at initial presentation as well as during the follow-up period. Also, metastasis should be considered in all pediatric patients with solitary mass lesions showing unconventional histology for a primary parotid neoplasm.

A 6 yr old castrated male English springer spaniel was evaluated with a 1 mo history of progressive right forelimb lameness with recent swelling around the elbow joint. Physical examination findings included lameness of the right forelimb, muscle atrophy around the right shoulder, grade 2/6 heart murmur, and moderate dental disease. Results of a complete blood cell count and serum biochemical analysis were unremarkable with the exception of a mildly increased alkaline phosphatase (368 U/L; reference range, 128–328 U/L). Radiographs of the right elbow revealed a mixed lytic and proliferative osseous lesion most consistent with either neoplasia or infection. Thoracic radiographs and the echocardiogram were unremarkable. Fine-needle aspiration of the bone lesion was performed. The cytological diagnosis was chondrosarcoma. The right forelimb was amputated and the axillary lymph nodes were collected. Histopathological examination of the bone lesion and axillary lymph nodes revealed chondrosarcoma with metastasis to the lymph nodes. Lymph node metastasis of chondrosarcoma is rare and needs to be further evaluated as a prognostic indicator.

Popliteal artery thrombosis may present as a complication of an osteochondroma located in the vicinity of the knee joint. This is a case report of a 26-year-old man with symptoms of the right lower extremity ischaemia without a previous history of vascular disease or trauma. Plain radiography, magnetic resonance angiography and Doppler ultrasonography documented the presence of an osteochondrous structure of the proximal tibial metaphysis, which displaced and compressed the popliteal artery, causing its occlusion due to intraluminal thrombosis..The patient was operated and histopathological examination confirmed the diagnosis of osteochondroma.

A 7-year old female collie (case 1), a 3-year old male Caucasian-cross (case 2) and three male German shepherds with an age of 11 (case 3), 8.5 (case 4) and 10 (case 5) years, respectively, were admitted with a history of decreased appetite, depression, exercise intolerance, dyspnea and progressive abdominal enlargement, for the last 10 to 60 days. Poor body condition (5/5), muffled heart sounds (5/5), weak femoral pulse (5/5), ascites (5/5), inspiratory or inspiratory-expiratory dyspnea (5/5), pulsus paradoxus (2/5) and jugular vein distension (2/5) were the prominent clinical findings, while mature neutrophilic leukocytosis (3/5), lymphopenia (3/5), eosinopenia (3/5), hypoproteinemia (5/5) and increased urea nitrogen (3/5) were the most prevalent clinicopathologic abnormalities. Apart from a space-occupying lesion onto the right atrial wall of one dog (case 4), radiographic and ultrasound examination showed a globe-shaped cardiac silhouette (5/5), pericardial effusion (5/5), ascites (5/5) and pleural effusion (4/5). A large amount of non-clotting hemorrhagic effusion was drained during pericardiocentesis, resulting in rapid clinical recovery. Physical, chemical and cytological evaluation of the pericardial fluid was non-contributory in the differentiation between neoplastic and non-neoplastic causes of these effusions. Case 3 died 25 days post-pericardiocentesis; right atrium hemangiosarcoma and pulmonary metastases were documented on post mortem histopathological examination. Another dog (case 5) died of unknown causes one month after pericardiocentensis. On the contrary, dogs 1, 2 and 4 were still clinically healthy for a followup period of 16, 2 and 8 months, respectively.

Mixed Tumours

Canine thyroid tumours are uncommon and the majority of tumours are carcinomas or adenomas, with only very few mixed tumours or metastases from distant sites described to date. A primary thyroid haemangiosarcoma has never been reported in veterinary medicine. In this case report, we describe a dog with a history of a large, non-painful, mobile ventral neck mass in the right paralaryngeal region. CT and ultrasound-guided fine needle aspirates were used for clinical staging. The mass was surgically excised and histopathological examination indicated a haemangiosarcoma. Abdominal ultrasound revealed the presence of splenic nodules and splenectomy indicated the presence of haemangiosarcoma. Chemotherapy with doxorubicin was started, but the dog was euthanased after three rounds of therapy, 97 days after the mass was discovered.

We describe an unusual cause of cranial dural thickening in an elderly female with a chronic meningeal inflammatory process. A 70-year-old ethnically Chinese, Singaporean female presented with a history of chronic daily headache with no other meningeal signs. Serial MRI brains showed progressive pachymeningeal and leptomeningeal enhancement in the left frontal region with underlying vasogenic oedema, similar appearances in the right frontal region to a lesser extent, and persistent inflammatory changes in her bilateral paranasal sinuses. Investigative work-up showed a chronically raised ESR with a normal CRP, negative ANCA, and a chronically raised serum IgA kappa paraprotein. Bone marrow trephine biopsy was suggestive of a low level plasma cell disorder. Olfactory cleft biopsy showed no evidence of IgG4-related disease or vasculitis and no significant plasma cell infiltrate. Histopathological examination from a meningeal biopsy revealed a diagnosis of an en-plaque meningioma (the WHO, 2016; Grade I) causing an unusual granulomatous reaction. We discuss the radiological and histological relations of this rare form of meningioma. Clinicians can consider en-plaque meningioma in the differential diagnosis of linear dural thickening and enhancement.

Subdural osteomas are extremely rare benign neoplasms. Here, we report the case of a 35-year-old female patient with a right frontal and parietal subdural osteoma. The patient presented with a 2-year history of intermittent headache and fatigue. Computerized tomography (CT) scan showed a high-density lesion attached to the inner surface of the right frontal and parietal skull. Magnetic resonance imaging (MRI) demonstrated T1 hyperintensity and T2 hypointensity of the lesion. Intraoperatively, the hard mass was located in subdural space and attached to the dura mater. Histopathological examination revealed lamellated bony trabeculae lined by osteoblasts and the intertrabecular marrow spaces occupied by adipose tissue. The patient underwent neurosurgical resection and recovered without complication. Surgical excision is recommended to extract the symptomatic lesions with overlying dura mater.

SummaryA nine-year-old male castrated European Shorthair cat was presented with a six-day history of progressive depression and ataxic gait. Neurological examination revealed depression, absent menace in the left eye, absent pupillary light reflex in the right eye, anisocoria, circling to the right, and delayed proprioception in all limbs. Magnetic resonance imaging showed a space-occupying right temporal lobe lesion adjacent to a small defect in the temporal bone suggestive of a meningo-encephalitis with concurrent abscess formation. The site was surgically approached by a rostrotentorial craniectomy. A cerebral abscess was found and debrided. Histopathological examination of the removed tissue demonstrated a subacute to chronic purulent encephalitis with extensive necrosis of brain tissue. Neurological symptoms resolved completely within two weeks and full recovery was observed four weeks after surgery.

AbstractA 62-year-old man presented to the Emergency Department with a 2-day history of right testicular pain. The initial diagnosis was orchiepididymitis (later found to be mistaken), and intravenous antibiotic treatment was started. Twenty-four hours later, the patient had mild pain in the right inguinal area and right infra-abdominal area. We performed an inguinal ultrasound that showed an incarcerated mass of mixed echogenicity in the right inguinal area. Surgery was performed because we thought the patient had an inguinal incarcerated hernia. Two days after the surgical procedure, the patient began to have fever and erythema and pain in the back. Abdominal computed tomography (CT) showed an acute pancreatitis with a peripancreatic collection from the pancreas to right inguinal area. We have reviewed similar cases in the literature and note that, infrequently, an inguinal mass can be the first sign of mostly asymptomatic acute pancreatitis.

Extrauterine parasitic lipoleiomyoma is a very rare fatty tumor, with uncertain histopathogenesis. Although imaging studies play an important role in preoperative localization and diagnosis of lipoleiomyoma, a pathological evaluation is paramount for confirmation of diagnosis. We describe a case of a 49-year-old woman with a palpable mass in the right inguinal area. Computed tomography of the abdomen and pelvis revealed a fluid- and fat-containing mass. Histopathological examination of the mass, which was successfully resected, confirmed the diagnosis of lipoleiomyoma. The patient was discharged on a postoperative day 2 without any complications.
