Perivascular Epithelioid Cell Tumors (PEComas) are a family of rare neoplasms defined as mesenchymal tumors composed of histologically and immunohistochemically distinctive perivascular epithelioid cells [1]. Pea et al. first noted this unusual cell type in both renal angiomyolipoma (AML) and clear-cell “sugar” tumor (CCST) of the lung [2]. This generated the concept of a family of neoplasms co...
Biliary cystadenomas with ovarian like mesenchymal stroma are rare benign cystic neoplasms of liver which have premalignant potential. A 58-year-old woman presented for the evaluation of a 3.6 cm cyst compressing the hepatic duct, jaundice and abnormal liver enzymes. Endoscopic retrograde cholangiopancreatography (ERCP) and stent placement provided symptomatic improvement. The patient was succe...
Spindle cell neoplasms are defined as neoplasms that consist of spindle-shaped cells in the histopathology. Spindle cell neoplasms can affect the oral cavity. In the oral cavity, the origin of the spindle cell neoplasms may be traced to epithelial, mesenchymal and odontogenic components. This article aims to review the spindle cell neoplasms of the oral cavity with emphasis on histopathology. ...
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.

Gene therapy consists of the transfer of genetic material to cells to achieve a therapeutic goal. In the field of gastroenterology and hepatology gene therapy has produced considerable expectation as a potential tool in the management of conditions that lack effective therapy including non-resectable neoplasms of the liver, pancreas and gastrointestinal tract, chronic viral hepatitis unresponsi...
