Ectopia of the pancreatic tissue is a developmental anomaly found in ~2% of all autopsies, and 70~90% of these anomalies are located in the gastrointestinal tract. Mediastinal localization of an ectopic pancreas is extremely rare. Herein, we report two cases with mediastinal ectopic pancreas clarified by pathology and shown by thoracic contrast-enhanced computed tomography (CT) and magnetic res...

An elderly woman presented with dyspnoea secondary to extensive mediastinal invasion by a primary well differentiated liposarcoma of the mediastinum. Five years after partial resection and postoperative radiotherapy (45 Gy) she is alive and well. To our knowledge, long term survival has not previously been reported for a non-encapsulated mediastinal liposarcoma treated by incomplete resection -...

A perivascular epithelioid cell neoplasm (PEComa) in the chest is rare, let alone in the mediastinum and lung. A 63-year-old man was admitted to our hospital with chest pain for more than 2 months and was found to have an opacity in his mediastinum and lung for 3 weeks. Enhanced chest computed tomography (CT) revealed a mass in both the left upper lobe and central anterior mediastinum. To ident...

INTRODUCTION The aim of the study was to assess the diagnostic yield of ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) in mediastinal or hilar adenopathy in: 1) staging of non-small cell lung cancer (NSCLC) (97); 2) other malignant neoplasms including: small cell lung cancer (SCLC), metastatic neoplasms and Hodgkin's disease (16); 3) NSCLC recurrence (7); 4) sarcoidosis and othe...

There is no existing worldwide published method for mediastinum compartment classification based on transverse section images for the differential diagnosis of mediastinal tumors. Herein, we describe a new method for anatomic mediastinal compartment classification using transverse section computed tomography (CT) images and the use of this method to classify mediastinal lesions, and thus evalua...

Pleuropulmonary blastoma (PPB) is a rare malignant dysontogenetic neoplasm primarily affecting children and is characterized histologically by a variably mixed blastematous and sarcomatous patterns. We herein report a very exceptional adult case of PPB. A 21-yr-old male patient presented with a left chest pain of two weeks' duration. A computed tomography scan revealed a large, multicystic tumo...

Cystic lesions of pancreas include a myriad of different conditions ranging from the common pseudocyst to unusual cystic neoplasm. With the development of better imaging modalities, cystic neoplasms are diagnosed with greater frequency and accuracy leading on to better understanding of the natural course of these lesions. Serous cystadenoma is one of the rare neoplasms of the pancreas that is u...

Thymoma is a rare tumor derived from thymus epithelial cells and occurs mostly in patients between 40 and 60 years old with slight male predominance. Thymomas account for less than 1% of the human neoplasms. They are rare in children and young adults [1]. Fine needle aspiration cytology of thymic epithelial neoplasms remains an underutilized method of sampling mediastinal masses. A cytologic di...

Liposarcoma arising in the mediastinum is extremely rare. Herein we present a case of a 47-year-old man with a huge posterior mediastinal tumor that extended to the bilateral thorax. The patient underwent a complete resection of the tumor and experienced an uneventful recovery. Postoperative pathology finally revealed liposarcoma. The patient underwent follow-up for 25 months, during which time...
