A thymolipoma is a slow-growing, anterior mediastinal tumor, rare in childhood. The authors present a report of a 4-year-old girl with persistent right thoracic hypotransparency on the chest radiograph. Computed tomography and magnetic resonance imaging revealed an anterior, well-limited, mediastinal mass of heterogeneous density, with lipomatous and soft tissue density areas. The tumor was totally excised and the histopathologic findings revealed a thymolipoma. A year and a half after surgery, the child remains well...

During the 2011 restoration works in the central nave of the church of the Assumption of Our Lady, known as "The Piquete", in the village of Quinto (about 50 kms southwest of Zaragoza, Spain), the remains of 70 individuals were uncovered. Of these there were 32 mummified bodies, four of which have been investigated with CT scans. Here we report on the findings in one such individual, namely a child of between 7 and 8 years of age, whose sex is debatable but may well be female. The main pathological finding is the presence of pressure erosion and distortion of the upper thoracic spine, the cause of which is discussed with the conclusion that this may well represent a neurenteric duplication cyst...

The thymus gland possesses the ability to regrow in children leading to a newly developed anterior mediastinal mass. This condition may represent a rebound phenomenon during recovery from a stressful event such as post-chemotherapy and hence was described as RTH. RTH after LT has not been well documented. We are reporting an infant with BA who underwent LT and presented with a symptomless anterior mediastinal mass, detected on follow-up imaging 6 months thereafter. Surgical partial excision was performed to rule out other differential diagnoses of a solid mass in the anterior mediastinum of an infant particularly lymphoma-that may arise as post-transplant lymphoproliferative disorder-and teratoma, as well as the other aggressive lesions such as thymoma and thymic carcinoma...

Thymomas are exceedingly rare tumours of the anterior mediastinum in children. An early awareness helps timely surgical intervention. Thymomas can occasionally be extremely aggressive. The loss of contour on chest X-Ray, to be confirmed as a large anterior mediastinal mass at computerised tomography, serves identification of a typical bilobed thymic tumour.

Thymolipoma is a rare disease among benign tumors. We herein report the case of a child who underwent thoracoscopic resection of a large thymolipoma. A 3-year-old boy was diagnosed with an anterior mediastinal solid tumor. Thoracic imaging revealed a fat density mass that was 8.0 × 5.0 × 3.5 cm in size. Given the MRI findings of the tumor, we suspected that the lesion was a teratoma. We decided to perform thoracoscopic exploration and, if possible, resection of the solid tumor sequentially. We successfully resected the tumor thoracoscopically...

Histoplasmosis is a common fungal infection, normally infecting people exposed to demolition sites or bat/bird droppings in the central and eastern states. When a child presents with a chest mass and eosinophilia in a non-endemic region the likelihood of an infectious process like pulmonary histoplasmosis is unknown. A seven year old immunocompetent child with a mediastinal mass and eosinophilia presented with acute cough, fever, non-bloody emesis, and four pound weight loss. A neoplastic work up was negative...

Primary mediastinal leiomyomas are extremely rare, its etiology unknown, and up to the present has only been described in a few cases in the English literature. In this case report, we describe a 3-year-old girl with asymptomatic left upper quadrant abdominal mass. Chest computed tomography demonstrated a giant solid mass in the anterior mediastinum, which extended to the right hemi-thorax and left upper quadrant abdomen. Fortunately, the girl underwent a complete surgical tumor resection. The definitive diagnosis was primary mediastinal leiomyoma...

BACKGROUND: Germ cell tumors (GCTs) in children are rare neoplasms with diverse pathological findings according to the site and age of presentation. The most common symptoms in children with mediastinal GCTs, which are nonspecific, are dyspnea, chest pain, cough, hemoptysis, vena cava occlusion syndrome, and fatigue/weakness. Because of these nonspecific symptoms, it is difficult to suspect a mediastinal mass. A posterior mediastinal tumor causing spinal cord compression is an important example of an oncologic emergency arising from a neurogenic tumor...

Thymic carcinoma with central nervous system involvement is very rare in children. A 27-month-old girl presented with a unilateral squint, vomiting, and behavioral changes. Imaging studies showed a silent anterior mediastinal mass and a large metastatic mass at the base of the skull. Biopsy of the anterior mediastinal mass confirmed an undifferentiated tumor consistent with thymic carcinoma. The child died within 3 months of the onset of symptoms, due to progression of the disease. These lethal tumors of unknown histogeneses and etiology are aggressive in nature, resistant to therapy, and have a rapidly fatal course...

Mediastinal masses are benign or malignant tumours that originate from the thymus, thyroid, lung, lymphoid system, pleura, or pericardium. Cardiovascular and respiratory symptoms may occur because of the compression of surrounding tissues along with growing mass. In this study, we present the anaesthetic management of a 6-month-old child having a massive anterior mediastinal mass that had a compressing effect.

INTRODUCTION: In children, malignant tumors presenting as a calvarial mass that too as initial manifestation are unusual. Also, brain metastases per se are rare in pediatric solid tumors with an incidence of just 1.5%. CASE DESCRIPTION: We present a child with calvarial metastasis which was the presenting symptom of an otherwise asymptomatic large malignant mediastinal germ cell tumor (GCT). The lesion was dural-based involving both calvaria as well as the underlying brain parenchyma...

OBJECTIVE: Primary malignant mediastinal germ cell tumors (MMGCTs) are rare in children and adolescents and have a poorer prognosis than their gonadal counterparts. We report a single institutional experience of a 10-year period of primary advanced MMGCTs treated with chemotherapy, followed by radiotherapy in those who had residual mass. METHODS: Children and adolescents with primary advanced MMGCTs between 2005 and 2014 were identified from the Cancer Center, Sun Yat-Sen University...

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...

As the conventional histopathologic examination of thymic carcinoma (TC) is nonspecific, immunohistochemical studies along with correlative radiographic investigations are needed for its correct diagnosis. TC commonly occurs in the late 5th to early 6th decades of life but is extremely rare in childhood. It may be incidentally detected from chest radiographs taken as routine or for other reasons. However, most patients present with symptoms such as chest pain, cough, shortness of breath, dysphagia and hoarseness, which are directly attributable to the mediastinal mass...

Cardiac tumors presenting as mediastinal masses in childhood are rare. This report describes the case of a 6-year-old girl who presented to us after a failed attempt at resection of a mass arising from the left atrial appendage. Computed tomography-guided biopsy suggested a perivascular epithelioid cell tumor (PEComa). Sirolimus was started in order to reduce the mass size. She subsequently underwent resection of the mass by midline sternotomy approach and cardiopulmonary bypass. Recovery was uneventful and the child is doing well at two-year follow-up...

We report a 5-year boy presenting with pain in the lower chest and upper abdomen. On evaluation with computed tomography scan of the chest, he was found to have a large 16 x 14 cm posterior mediastinal mass compressing the inferior vena cava and liver, and shifting the heart to the opposite side. Tumor was approached via right postero-lateral thoracotomy and dissected off from esophagus, heart, inferior vena cava and lungs. The entire tumor was resected without any complications. Postoperative course was unremarkable...

BACKGROUND & OBJECTIVES: Mediastinal lesions are uncommon and are infrequently encountered in routine clinical practice. Hence, there is a need for more elaborate studies of mediastinal lesions to make the pathologists and clinicians aware of the large spectrum of these lesions. The present study describes the histomorphological spectrum of various mediastinal lesions in a tertiary care hospital in India, along with the discussion of some unusual and interesting cases. Considering the limited diagnostic material obtained in guided biopsies, the adequacy of such tissue for providing a definite opinion was also evaluated...

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...
