A previously healthy 7-month-old male infant presented for evaluation of fever, deceased oral intake, and intermittent noisy breathing. Physical examination revealed neck tenderness. Soft tissue neck radiographs and computed tomography (CT) scan supported a diagnosis of retropharyngeal swelling with extension to the superior mediastinum. Surgical exploration was planned, and endotracheal intubation was performed in the operating room. Significant cardiorespiratory derangements developed immediately after the tracheal tube was inserted, including hypotension, hypoxia, and bradycardia with signs of cardiac ischemia...

OBJECTIVE: Diabetes mellitus, smoking, dyslipidemia, and obesity play an important role in the etiology of erectile dysfunction, particularly in cases with vascular insufficiency. These risk factors also target the lungs due to their systemic effects. MATERIALS AND METHODS: Patients with penile vascular insufficiency determined at Doppler ultrasonography and undergoing thoracic computerized tomography for various reasons were included in this study. A history of acute thoracic trauma, pneumonic consolidation, or pelvic surgery and trauma were regarded as exclusion criteria...

Aspergillus is described as mould characterised by septate hyphae about 2-4μ in diameter, it is ubiquitous in nature and spreads by inhalation of spores. It causes opportunistic infections in almost six forms namely Allergic bronchopulmonary aspergillosis, Aspergillus sinusitis, Cutaneous aspergillosis, Aspergilloma, Chronic pulmonary aspergillosis, Invasive aspergillosis. Invasive aspergillosis of mediastinum in an immunocompetent patient has rarely been reported. We present a case of a young male who had presented with chest pain, cough and breathleness was later diagnosed as fulminant mediastinal aspergillosis...

Large posterior mediastinal masses may lead threatening complications such as critical tracheobronchial compression. Airway management in these individuals is a challenge and being a lower airway obstruction; rescue strategies are limited. We encountered one such case of a large esophageal mucocele causing extrinsic tracheobronchial compression. We have described the anesthetic management of this case using awake fiber-optic assessment followed by intubation. Close communication with the surgical team, meticulous planning of airway management, and early drainage of the mucocele are the cornerstones of management in such patients...

An 11 years old boy was referred to our hospital. He complained for the last three months for intermittent cough and shortness of breath after exercise which worsened recently. Airways computed tomography (CT) showed an abnormal endobronchial tumor, obstructing the right main bronchus and also atelectasis in the upper lobe of the right lung. Bronchoscopy showed a wet on its surface mass obstructing the right main bronchus. Biopsy showed a mucoepidermoid carcinoma (MEC). The fluorine-18-fluorodeoxyglucose positron emission tomography/computed tomography ((18)F-FDG PET/CT) scan showed in the same area a mass with slightly increased (18)F-FDG uptake (maximum standardized uptake value, SUVmax: 3...

INTRODUCTION: Ectopic cervical thymus (ECT) is a rare embryological abnormality in children. It can be revealed by a compressive neck mass mistaken for a malignant tumor. Through a new case of ECT, we review the embryopathogenesis, diagnostic difficulties and therapeutic features. CLINICAL OBSERVATION: A 19-month-old girl presented a right cervical mass that quickly increased in size, causing intermittent dyspnea. The physical examination objectified a 6-cm, soft and compressible, painless right cervical tumefaction, extending from the mastoid area to the ipsilateral supraclavicular fossa...

Acquired myasthenia gravis (MG) is relatively uncommon in cats. In humans, MG may be associated with other immune-mediated disorders, in particular polymyositis (PM). In this study, we described in-depth electrodiagnostic findings and pathological changes in muscles of cats diagnosed with MG, and assessed the presence of concurrent PM. Six cats with confirmed acetylcholine receptor antibody seropositive MG, and two suspected cases with clinical signs and electrophysiological changes consistent with MG, were reviewed...

Adult community-acquired pneumonia (ACAP) is the most prevalent pulmonary infectious disease that may be asymptomatic or have varying clinical presentations. Patients with ACAP often present with enlarged mediastinal lymph nodes on their chest computed tomography images. However, large irregular swollen lymph nodes are rarely reported in ACAP, and may therefore be confused with enlarged lymph node masses. In the present case report, the patient presented with lymph node masses, which were ameliorated to their normal size following antimicrobial treatment...

Nuclear protein in testis (NUT) midline carcinoma (NMC) is a rare, aggressive, lethal, epithelioid, poorly differentiated cancer first described in Japan in 1991, unique in that is defined genetically rather than by histological tissue of origin. It usually arises in the body midline and presents as a mass with metastasis. An infant presenting with pneumonia was found to have a pericardial mass, NMC resected, and subsequent staging positron emission tomography (PET) showing residual mediastinal tumor and midline abdominal metastases...

Classical Hodgkin lymphoma (cHL) and anaplastic large cell lymphoma (ALCL) feature high expression of AP-1 transcription factors, which regulate various physiological processes but also promote lymphomagenesis. The AP-1 factor basic leucine zipper transcription factor, ATF-like 3 (BATF3) is highly transcribed in cHL and ALCL; however, its functional importance in lymphomagenesis is unknown. Here we show that proto-typical CD30(+) lymphomas, namely cHL (21/30) and primary mediastinal B-cell lymphoma (8/9), but also CD30(+) diffuse large B-cell lymphoma (15/20) frequently express BATF3 protein...

Thymopharyngeal duct cyst is one of the most uncommon benign cervical lesions encountered in the paediatric population. Due to its rarity, it almost always escapes a correct preoperative diagnosis and is usually misdiagnosed as a branchial cyst or lymphangioma. Furthermore, although located at the neck it may present with retrosternal or mediastinal extension. In this case report here we present a case of a young boy with a right cervical mass, diagnosis of thymopharyngeal duct cyst was confirmed during histopathological examination of the excised specimen...

A parathyroid adenoma present in an ectopic site, in the anterior mediastinum, is a rare cause of persistent hyperparathyroidism. Though its occurrence in the mediastinum is unusual, existence has been noted in literature for more than a century. We describe a case of a 35-year-old male presenting with complaints of pain abdomen, clinically diagnosed as acute necrotizing pancreatitis, with raised serum calcium. Patient received symptomatic treatment for the pancreatitis which subsided. However, high levels of serum calcium persisted...

Interest in preclinical drug development for ovarian cancer has stimulated development of patient-derived xenograft (PDX) or tumorgraft models. However, the unintended formation of human lymphoma in severe combined immunodeficiency (SCID) mice from Epstein-Barr virus (EBV)-infected human lymphocytes can be problematic. In this study, we have characterized ovarian cancer PDXs which developed human lymphomas and explore methods to suppress lymphoproliferative growth. Fresh human ovarian tumors from 568 patients were transplanted intraperitoneally in SCID mice...

A 57-year-old man presented to the surgical oncology clinic with a mildly tender mass under his right arm. Four years prior, the patient had a melanoma removed from his right shoulder along with an ipsilateral right axillary sentinel lymph sampling. Computed tomography (CT) scan was negative for metastatic disease at that time. The patient did not undergo completion axillary node dissection and was lost to follow-up. The patient was originally from Australia, did not tan but reported multiple sunburns before age 18...
