Common location of teratomas in children are sacrococcygeal, gonadal, mediastinal and retroperitoneal, but teratomas may also occur at very unusual locations. A six-month-old boy presented with a large swelling at his left lumbar region. He presented with gradually increasing lump at his back, involving more on left lumbar region and midline since birth. Clinical examination revealed a solitary, non-tender, soft to firm, irregular mass, occupying more on his left lumbar and midline region and also crossing the midline...

The paper describes a periprosthetic metastatic lesion in the stem region which developed 4 years after cementless total hip arthroplasty in a 64-year-old female patient. The patient underwent primary THA due to osteoarthritis in 2010. In June 2014, she presented with increasing hip pain. Diagnostic imaging revealed a periprosthetic osteolytic lesion in the stem region. The patient was referred to the Orthopaedic Department for further evaluation with a suspicion of pyogenic osteomyelitis. An open surgical biopsy was performed...

BACKGROUND: Clear cell sarcoma (CCS) is a rare malignant soft-tissue neoplasm that displays melanocytic markers and exhibits striking histopathological features. The tumour has a predilection for the lower extremities and rarely presents in the mediastinum. CASE PRESENTATION: We present a case of primary mediastinal CCS in a 57-year-old man. Computer tomography (CT) revealed a 12 × 12 × 7.5 cm mass in the anterior mediastinum. Microscopically, the tumour mainly consisted of epithelioid cells with oval vesicular nuclei and eosinophilic cytoplasm...

Uniportal thoracoscopic resections offer less pain and better cosmetic results. They are usually performed through an antero-lateral incision. Posterior uniportal approach has not been described yet. A 65-year-old female was admitted to our clinic for the treatment of an adenocarcinoma, located in the apical segment of the right lower lobe. Owing to the ideal location and size, anatomical segment resection and radical lymphadenectomy was planned. Fissureless video-assisted thoracoscopic resection of the apical segment of the right lower lobe, using a uniportal posterior approach was performed, followed by mediastinal lymphadenectomy...

BACKGROUND: Receptor for advanced glycation end-products (RAGE), a receptor for amyloids, is constitutively expressed in lungs and generally observed to be downregulated in lung cancer tissues. However, increasing levels of RAGE or serum amyloids is associated with poor outcome in lung cancer patients. We report a rare case of primary systemic amyloid light-chain (AL) amyloidosis in biopsy-proven multiple organs with early-stage non-small cell lung cancer (NSCLC) that displayed strong staining for RAGE in the tumour tissue...

OBJECTIVE: The mediastinum is the central portion of the thoracic cavity, housing numerous organs and harbouring a mixed bag of non-neoplastic and neoplastic lesions. Accurate diagnosis is essential owing to the widely variable therapeutic and prognostic implications. MATERIAL AND METHOD: Cases of mediastinal masses were retrospectively reviewed from January 2011 till January 2016. Clinico-radiological records of these cases were retrieved. Fine needle aspiration cytology (FNAC) was performed wherever feasible...

INTRODUCTION AND OBJECTIVE: Mediastinal lymph node involvement can be understaged in cases of lung cancer (up to 20% in stage i). Sentinel node detection is a standard technique recommended in breast cancer and melanoma action guidelines, and could also be useful in cases of lung cancer. MATERIAL AND METHODS: Considering the detection of the sentinel node in non-small cell lung cancer (NSCLC) as feasible, a prospective cohort study was carried out on 48 patients with resectable NSCLC, using the intraoperative injection of colloid sulphate technetium-99...

Primary tumours originating from the pericardium are extremely rare. Previous studies have reported that these tumours account for only 6.7-12.8% of all mediastinal tumours with an overall prevalence of 0.001% to 0.007%. The majority of these tumours are benign lipomas or pericardial cysts. The most common pericardial malignancy is mesothelioma. Sarcomas are soft-tissue mesenchymal malignancies originating from various parts of the body but are extremely rare in this area. We report a case of a 52-year-old female who was diagnosed with a primary sarcoma with rhabdoid differentiation originating from the pericardium...

Germ-cell tumours (GCTs) are derived from germ cells and occur most frequently in the testes. GCTs are histologically heterogeneous and distinctly curable with chemotherapy. Gains of chromosome arm 12p and aneuploidy are nearly universal in GCTs, but specific somatic genomic features driving tumour initiation, chemosensitivity and progression are incompletely characterized. Here, using clinical whole-exome and transcriptome sequencing of precursor, primary (testicular and mediastinal) and chemoresistant metastatic human GCTs, we show that the primary somatic feature of GCTs is highly recurrent chromosome arm level amplifications and reciprocal deletions (reciprocal loss of heterozygosity), variations that are significantly enriched in GCTs compared to 19 other cancer types...

We present a case of 16-year-old male, who was referred from private centre for dyspnoea, fatigue, and orthopnea. The chest radiograph revealed complete opacification of left chest which was confirmed by computed tomography as a large left mediastinal mass measuring 14 × 15 × 18 cm. The diagnostic needle core biopsy revealed mixed germ cell tumour with possible combination of embryonal carcinoma, yolk sac, and teratoma. After 4 cycles of neoadjuvant BEP regime, there was initial response of tumour markers but not tumour bulk...

Adrenal germ cell tumour is very rare. We report a case of a 59-year-old woman who presented with right flank discomfort. The laboratory examinations were normal and the chest computed tomography (CT) showed right pleural effusion. The abdominal CT scan revealed a large mass on the right adrenal gland. The patient underwent an adrenalectomy. Histopathologic examination and immunohistochemical findings were consistent with mixed germ cell tumour. Three months later following the operation, the patient was admitted to our hospital again with chest tightness and shortness of breath...

INTRODUCTION: Extragonadal germ cell tumours (EGCTs) are a heterogeneous group with distinct natural history and responses to treatment modalities. We sought to evaluate characteristics and survival outcomes in men with EGCTs. METHODS: We performed a retrospective analysis on a consecutive list of men diagnosed with EGCT in two Albertan cancer centres between 1990 and 2013. Demographic characteristics and outcomes, stratified by primary site, were evaluated. RESULTS: Sixty-nine cases were identified...

BACKGROUND: Guidelines recommend endosonography with fine-needle aspiration for mediastinal nodal staging in non-small-cell lung cancer, but most do not specify whether this should be through endobronchial endoscopy (EBUS), oesophageal endoscopy (EUS), or both. We assessed the added value and diagnostic accuracy of the combined use of EBUS and EUS. METHODS: For this systematic review and random effects meta-analysis, we searched MEDLINE, Embase, BIOSIS Previews, and Web of Science, without language restrictions, for studies published between Jan 1, 2000, and Feb 25, 2016...

Massive mediastinal tumours are rare in clinical practice and complete surgical resection may be associated with serious complications. Preoperative angiography and embolisation are valuable adjuncts in the management of giant tumours to decrease perioperative blood loss, provide a clear operative field and facilitate complete resection. We report the safe use of preoperative embolisation which facilitated excision via clamshell incision, of a highly vascular massive anterior mediastinal tumour with an unusual final diagnosis...

Mediastinal masses in children comprises of a heterogeneous group of tumours. In such cases, biopsy and histological analysis are mandatory for planning of treatment. We have reported an unusual aetiology for a mediastinal mass in a young boy presenting with features of Superior Vena Caval Obstruction (SVCO) who also had marked blood and marrow eosinophilia mimicking Chronic Eosinophilic Leukaemia (CEL). We have also discussed the differential diagnoses of mediastinal tumours with hyper-eosinophilia and possible therapeutic implications...

Leiomyoma is the most common oesophageal tumour and is symptomatic in about half of the patients. Dysphagia is the most common symptom. A 41-year-old woman presented with recent onset of severe orthostatic hypertension. During the cardiological work-up, a mediastinal mass was found at transthoracic echocardiogram. Further investigation (upper gastrointestinal endoscopy, endoscopic ultrasonography, CT scan and cardiac MRI) confirmed the diagnosis of a large oesophageal submucosal mass compressing the supradiaphragmatic inferior vena cava...

Thymoma is an epithelial neoplasm of the thymus. It commonly lies in the anterior mediastinum and represents 20-30% of mediastinal tumours in adults. In this report we present a case of giant thymoma locating in the anterior-inferior mediastinum. A 46-year-old male came to our institute with slight pectoralgia and dyspnea. Chest CT shows a giant tumor measuring 19 cm × 16 cm × 15 cm in the left thoracic cavity. After careful examination, we performed surgery. At surgery, we found the tumor was adherent to left upper lobe of the lung, mediastinal pleura, and parietal pleural...
