RESUMO
Teratomas are a type of germ cell tumor that may contain several different types of tissue. Neurofibroma is a benign peripheral nerve sheath tumor with the plexiform type being pathognomonic for neurofibromatosis type 1. We report a case of a 33-year-old woman with a background of Neurofibromatosis type 1 who presented with left-sided chest pain and shortness of breath. She was diagnosed with a large mediastinal mass which was confirmed from a CT-guided biopsy as neurofibroma. Following a multidisciplinary team discussion, she underwent mediastinal mass resection and the final histopathology report revealed mediastinal mature teratoma.
RESUMO
Desmoid tumours are rare, locally aggressive neoplasms exhibiting high tendency for recurrence, even after complete resection. Only 1 in 5 of them originates from the chest wall, usually measuring less than 10 cm at diagnosis. Herein, we report the case of a woman presenting with symptoms of gradual lung compression by a giant desmoid tumour occupying the entire hemithorax. She underwent complete surgical resection of the tumour and chest wall reconstruction. She had disease recurrence 15 months later and currently remains under regular follow-up. The management of intrathoracic desmoid tumours is challenging because they are usually not diagnosed until they become large enough to cause compression symptoms. While medical management is the primary modality of treatment, surgery could be considered in selected cases where significant symptoms arise, and the functional status is impaired secondary to the tumour. Adjuvant radiotherapy to minimise the risk of local recurrence should also be considered.

BACKGROUND: Congenital long-QT syndrome represents the most common cardiac channelopathy and manifests as potentially lethal ventricular arrhythmias. Prevention strategies include beta-blockade pharmacotherapy, implantable cardioverter-defibrillators, and left cardiac sympathetic denervation, which can increase the threshold for ventricular fibrillation. Herein, we report our experience with video-assisted thoracoscopic left cardiac sympathetic denervation. METHODS: We performed a retrospective review of the electronic medical records of all patients with congenital long-QT syndrome who underwent video-assisted thoracoscopic left cardiac sympathetic denervation at our institution. RESULTS: From September 2009 to May 2016, 6 patients with a mean age of 30.5 years (range 20-47 years) underwent video-assisted thoracoscopic left cardiac sympathetic denervation for medically refractory long-QT syndrome. All patients had an uneventful recovery and were discharged 1-3 days after the operation. At a median follow-up of 14 months (range 12-60 months), 4 patients had no cardiac events while 2 experienced 1 episode of arrhythmic syncope and 1 episode of appropriate implantable cardioverter-defibrillator shock. Following surgery, the mean annual cardiac events in the study cohort decreased from 2.13 to 0.33 (p = 0.004) and the mean corrected QT interval reduced from 560 ms to 491 ms (p = 0.006). CONCLUSIONS: Video-assisted thoracoscopic left cardiac sympathetic denervation is a safe and effective therapy in patients with congenital long-QT syndrome who continue to suffer from recurrent life-threatening arrhythmias or frequent implantable cardioverter-defibrillator discharges despite maximum tolerated doses of beta blockers.

Cystic fibrohistiocytic tumour of the lung is a very rare pathological entity that occurs either as a primary pulmonary neoplasm or as a metastasis from skin lesions called cellular fibrous histiocytomas. Herein, we present the case of a 19-year old man with a history of recurrent pneumothoraces who was managed surgically and was eventually diagnosed with cystic fibrohistiocytic tumour of the lung. Clinicians should include this disease in the differential diagnosis of pulmonary cystic lesions and be aware of its association with cellular fibrous histiocytoma. Reporting of more cases is warranted to further elucidate the natural course of the disease and optimise its management.

Long QT syndrome (LQTS) is an uncommon and potentially fatal cardiac channelopathy. Treatment options can be medical with ß-blockers or surgical with implantable cardioverter defibrillator (ICD) implantations and left cardiac sympathetic denervation (LCSD). Purpose of this paper is through a literature review to identify the management algorithm and the role of sympathectomy in LQTS.
RESUMO
Thoracic outlet syndrome (TOS) is a constellation of signs and symptoms caused by compression of the neurovascular structures in the thoracic outlet. TOS may be classified as either neurogenic TOS (NTOS) or vascular TOS: venous TOS (VTOS) or arterial TOS (ATOS), depending on the specific structure being affected. The basis for the surgical treatment of TOS is resection of the first rib, and it may be combined with scalenectomy or cervical rib resection. Herein, we describe a case of arterial thoracic outlet syndrome which was successfully treated with totally endoscopic video-assisted thoracoscopic surgery (VATS) first rib resection.
