While the small intestine accounts for nearly 75% of the total length of the GI tract and more than 90% of the mucosal surface area, less than 25% of all alimentary tract neoplasms and less than 2% of all malignant tumours originate from the small intestine. This could be due to the relatively rapid transit time, liquid content of stools, low bacterial population, and a high concentration of Ig...

Conventional PA and lateral chest radiographs continue to be the initial examination of choice to evaluate patients who are suspected of having a pulmonary parenchymal neoplasm. A lung lesion can be characterized as probably benign or malignant based on its radiographic appearance (size, shape, margins, presence of calcification, cavitation or air bronchograms, growth rate). A spiculated or lob...

Thymic epithelial tumors (TET) are rare mediastinal neoplasms that can metastasize to the pleural space (stage IVA). Complete surgical resection remains the backbone of therapy for patients with early stage TET, however, the role of surgery in the management of patients with stage IVA disease is not fully defined. Published reports in this regard are mainly small, retrospective, and uncontrolle...

Spiral computed tomographic (CT) data sets coupled with a real-time volume-rendering technique allow creation of accurate three-dimensional (3D) images that can be used for a wide range of clinical applications. The image contrast of and relative pixel attenuations in the final image can be interactively modified by the user in real time by manipulating trapezoidal transfer functions. Although ...

Carcinosarcoma of the esophagus is a malignant neoplasm involving both carcinomatous and sarcomatous components. We report a patient with true esophageal carcinosarcoma who underwent laparoscopy-assisted surgery. An upper gastrointestinal barium study revealed a lobulated intraluminal filling defect in the lower intrathoracic esophagus. The patient underwent esophagectomy and regional lymphaden...

Extramedullary plasmacytoma (EMP) is an uncommon plasma cell neoplasm results from plasma cell proliferation and consists of monoclonal plasmacytic infiltration, without bone marrow involvement and any other systemic characteristics of multiple myeloma. EMP accounts for 3% of all plasma cell neoplasms and approximately 80% to 90% of EMP involve submucosa of the upper aerodigestive, while scrota...

Benign tumors of the mediastinum may on occasion reach massive proportions. Previous reports on mediastinal tumors made by Clagett and others include a fibroma weighing over 4000 gm successfully removed, and a lipoma (autopsy specimen) of 12,000 gm. Ganglioneuroma of the mediastinum is a rare lesion and is almost always posterior in origin. Three of 71 cases reviewed by Kent and Blades were in ...

Primary liposarcoma of the mediastinum is an uncommon tumour. We report a case of a 45-year-old female who was found incidentally to have a large anterior mediastinal mass. Complete removal of the tumour was accomplished successfully. Appropriate immunohistochimical stains were performed, confirming the presence of a well-differentiated liposarcoma of the mediastinum. We describe an unusual cas...

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...
