Introduction Approximately 32,000 pancreatic neoplasms are diagnosed in the United States annually.1 Currently, carcinoma of the pancreas is the fourth most common cause of cancer death in both men and women in this country, after cancers of the lung, breast/ prostate, and colon. The most common presenting symptoms of pancreatic cancers are epigastric pain, obstructive jaundice, and weight loss...

Adenoid cystic carcinoma (ACC) is a relatively rare epithelial tumor of the salivary glands that accounts for approximately 5 to 10% of all salivary gland neoplasms. The typical clinical and pathological findings of this tumor include slow indolent growth, common local recurrence, and late distant metastasis to lung, brain, bone, liver, thyroid, and spleen. We report a 52-year-old female patien...

Birt-Hogg-Dubé syndrome (BHDS) is an autosomal dominant inherited disorder caused by germline mutations in the FLCN gene, and characterized by skin fibrofolliculomas, multiple lung cysts, spontaneous pneumothorax, and renal neoplasms. Pulmonary manifestations frequently develop earlier than other organ involvements, prompting a diagnosis of BHDS However, the mechanism of lung cyst formation and...

170 J Postgrad Med April 2008 Vol 54 Issue 2 lower lobes of the lungs, especially if it is in contact with the diaphragm, along with primary lung, pleural and diaphragmatic neoplasms as well as metastases and other non-neoplastic causes. A noninvasive imaging modality such as a CT scan with FNAC should establish the correct diagnosis and more invasive procedures like diagnostic pneumoperitoneum...

Primary sarcoma of the lung and/or pleural cavity is a rare finding accounting for <0.5% of all thoracic malignancies. Histologically, mesothelioma predominates in this subcategory of neoplasms; its relationship to asbestos exposure and cigarette smoking is well documented. Other tumor types include fibrosarcoma, malignant fibrous histiocytoma, angiosarcoma, leiomyosarcoma, synovial sarcoma, an...

Pulmonary hamartomas are benign tumors, which represent abnormal mixture of fibrous connective tissue, hyaline cartilage, fat and bone as well as bronchial epithelial cells. Differential diagnosis of tuberculoma, malignant neoplasms and hamartoma is necessary. We present the tuberculosis patient with pulmonary hamartoma mimicking lung tuberculoma. The uncorrected diagnosis of tuberculoma was ma...

Chordomas are rare neoplasms arising from notochordal remnants and may develop anywhere in the body while the most common anatomic site is the sacrococcygeal area. The most effective treatment of chordoma is surgery. Chordomas rarely metastasize to lung, bone, soft tissue, liver, lymph nodes, and skin. However, there is currently no standard systemic treatment for advanced stage chordoma. Here,...

The epidemiology of genitourinary cancer varies depend on the organ. Prostate cancer is the most common solid neoplasm in males (15%) and renal cell neoplasm involves since 3% of all adult cancers. Urothelial carcinomas are the fourth most common tumors, after prostate, breast (females), lung and colorectal cancer. In particular, bladder cancer is the 9th most common cancer diagnosis worldwide....

Solitary metastatic pancreatic lesions comprise 0.5% to 3% of all pancreas neoplasms, most commonly arising from primary tumors of the kidney, lung, or colon. Synchronous metastatic pancreatic lesions are exceptionally rare. Only 25 cases of isolated colorectal pancreatic metastasis amenable to resection have been reported, 11 of those in the distal pancreas. To our knowledge we report the firs...

To the editor: Soft tissue sarcomas are neoplasms which establish themselves on structures of mesodermic origin. The most common histological variant in adults is the malignant fibrous histiocytoma (MFH), though this rarely occurs in the lung. Furthermore, before labeling such a histiocytoma as being of pulmonary origin, it is important to rule out the possibility of a primary site elsewhere, g...
