Atypical Manifestation

The transmissible venereal tumour (TVT) is one of the most frequent neoplasias in dogs. This tumour has specific characteristics, and it is exclusively of canines. Its transmission occurs through viable neoplastic cell transplantation when in contact with mucosa or unhealthy skin and rarely metastasise. This paper aims to report a rare presentation of pulmonary metastasis of widespread transmissible venereal tumours in a Blue Heeler dog. The patient was cachectic, dyspnoeic, and dehydrated and had multiple skin and pharynx nodulations. The cytology of all cutaneous nodulations showed round vacuolated cells with large eccentric nuclei and loose chromatin, which is compatible with TVT’s microscopic characteristics. Owing to the clinical evolution and reserved prognosis, the patient was euthanized. Necroscopy revealed a mass in the right pulmonary caudal lobe. The mass showed the same histopathologic characteristic of the others: not encapsulated infiltrative neoplastic proliferation of round vacuolated cells. The atypical manifestation of cutaneous metastasis and mainly pulmonary metastasis, in this case, denote the importance of TVT inclusion as a differential in cutaneous neoplasia, even if they show distant organ metastasis. Therefore, it emphasised the importance of cytology and histology in the diagnosis of nodular affections.

Abstract Background Emphysematous pyelonephritis (EPN) with gas in the inferior vena cava (IVC) is a rare presentation and to our knowledge, this is the first case report in the urologic literature. Case presentation A 35-Year-old obese diabetic Hispanic female presented to the emergency room with a clinical picture of septic shock. Prompt computerized tomography scan revealed EPN with gas throughout the right renal parenchyma and extending to the right renal vein, IVC, and pulmonary artery. She died before surgical intervention Conclusion This case demonstrates that patients presenting with severe EPN have a high mortality risk and providers should acknowledge that septic shock, endogenous air emboli, or a combination of both could result in cardiovascular collapse and sudden death.

Prostate cancer is the most common cancer affecting men in the United States and the second greatest cause of cancer-related death. Metastases usually occur to bone followed by distant lymph nodes and then viscera. Cutaneous metastases are extremely rare. Their presence indicates advanced disease and a poor prognosis. As they are highly variable in appearance and may mimic a more benign process, biopsy is essential for identification. Serine proteases, particularly human tissue kallikreins, may play an important role in promoting metastasis and facilitate infiltration of the skin. Individual cancer genetics may predispose to more aggressive cancer and thus earlier and more distant metastases. In this article, we report our case of a 67-year-old man with a 4-year history of castrate-resistant prostate cancer with cutaneous metastases confirmed by histology. Despite multiple lines of systemic therapy, the patient suffered progressive disease with worsening performance status and was enrolled in hospice.

AbstractCardiac hydatid cysts are a rare presentation of hydatid cyst disease in the body, with a reported cardiac involvement rate of <2%. The left ventricle is the most common site of cardiac involvement. Here, we report a patient with a hydatid cyst that ruptured into the pericardium after producing an aneurysm on the right ventricular free wall, appearing as fibrinated fluid and a solid mass lesion in the pericardium. Our aim in this case report was to emphasise that the possibility of a hydatid cyst should not be overlooked in the differential diagnosis of pericardial tumours.

Background. Mediastinal thyroid carcinoma is extremely rare, with few cases reported in the literature. Case Report. A 73-year-old man presented with weight loss for 6 months. Imaging by computed tomography (CT) documented a large mediastinal mass below the thyroid gland and pulmonary metastases. Neck ultrasound found two spongiform nodules in the right thyroid lobe, and fine-needle aspiration citology (FNAC) of these nodules revealed they are benign. Endobronchial ultrasound-guided needle biopsy of the mediastinal mass was compatible with papillary thyroid cancer. A few weeks later, the patient developed overt hyperthyroidism due to Graves’ disease, which was treated with antithyroid drugs. 99mPertechnetate scintigraphy showed increased diffuse uptake in the thyroid parenchyma but the absence of uptake in the paratracheal mass and in the lung nodules. The patient was not considered eligible for surgical intervention or therapy with tyrosine kinase inhibitor due to tracheal and mediastinal vessel invasion and was treated with palliative radiotherapy. Two months later, restaging PET-FDG showed an intense uptake in the right lobe of the thyroid gland, lymph nodes, lungs, bone, muscle, myocardial, kidney, and adrenal gland. Conclusion. In this case, thyroid carcinoma presented as a mediastinal mass with concurrent hyperthyroidism due to Graves’ disease. Although uncommon, the clinicians should be aware of these situations. Obtaining a prompt histological examination of an intrathoracic mass is crucial to ensure an early diagnosis and treatment.

Atlantooccipital dislocation can be complicated by a traumatic durotomy that may lead to the rare development of a retropharyngeal pseudomeningocele. To our knowledge this has been reported only five times previously. We present the case of a 60-year-old man involved in a motor vehicle accident who suffered an atlantooccipital dislocation and C5-C6 three-column injury. A unique MRI image of a defect in the ventral dura posterior to C2 was appreciated. He underwent occiput to T2 internal fixation and arthrodesis. During surgery, CSF egress was seen caudal to the right C2 nerve root. A DuraMatrix onlay patch reinforced with DuraSeal was placed to stop the CSF leak. A lumbar subarachnoid drain was also placed. The patient made a satisfactory recovery with residual mild weakness of his right upper extremity. In this report, we demonstrate that careful MRI review can reveal a ventral durotomy in a traumatic atlantooccipital dislocation and, if discovered, effective treatment including a lumbar subarachnoid drain for CSF diversion may prevent progression to a retropharyngeal pseudomeningocele. The literature on this rare presentation and associated durotomy is provided.

Here we report an extremely rare presentation of internal jugular vein catheterization, presenting as massive hemoptysis which was noted during right internal jugular vein cuffed hemodialysis catheter insertion of a 39-year-old man known-case of End-Stage Renal Disease. Chest roentgenogram and computerized tomography scan showed pleural effusion and misplacement of the tip of hemodialysis catheter in the posterior mediastinum causing possible damage to the right main bronchus. After chest tube insertion and removing the misplaced hemodialysis catheter, a proper cuffed catheter was inserted and the patient was discharged with an uneventful post-op course.
