AIM: Extra-ampullary duodenal adenoma (EADA) is a rare condition with poorly described clinicopathological details. In this study, we aimed to clinicopathologically characterize EADA. METHODS AND RESULTS: We performed a retrospective review of 44 serial cases of EADA. Each EADA was categorized as either gastric-type (n=5) or intestinal-type (n=39). All gastric-type adenomas were located in the first portion of the duodenum and exhibited a pedunculated shape. Gastric-type adenomas were classified into two subtypes: a pyloric gland type and a foveolar type...

Lymphoepithelioma-like carcinoma (LELC) is a rare neoplasm of the cervix. The importance of distinguishing this undifferentiated carcinoma with a predominant lymphocytic infiltrate lies in the fact that despite being poorly differentiated they have a better prognosis. The diagnosis however becomes more challenging when the pathologist is provided with a small cervical biopsy or a Papanicolaou smear. While the reports describing histology and their relation to Epstein-Barr virus (EBV) are many, there are only few case reports describing the cytology of these tumors...

Vascular tumors of the breast are rare and may pose a diagnostic challenge. Breast hemangioma is a very rare benign vascular neoplasm accounting for 0.4% of all breast tumors. It is most commonly detected as an incidental microscopic finding in biopsy specimens obtained for unrelated reasons. We describe here a very rare case of a sinusoidal breast hemangioma in a postmenopausal patient who presented with a palpable breast mass. A complete surgical resection was performed because the tumor exhibited atypical imaging features...

Intraosseous hemangiomas are uncommon intrabony lesions, representing approximately 0.5 to 1% of all intraosseous tumors. Their description varies from "benign vasoformative neoplasms" to true hamartomatous proliferations of endothelial cells forming a vascular network with intermixed fibrous connective tissue stroma. These commonly present as a firm, painless swelling. Intraosseous hemangiomas present more commonly in females than in males and most likely occur in the fourth decade of life. The most common etiology of intraosseous hemangioma is believed to be prior trauma to the area...

Neuroblastoma is the most common solid malignant neoplasm in the paediatric age group; accounting for 7% of all childhood malignancies, but neuroblastoma in adult, is a rare occurrence, finding mention in aeons of medical literature with an overall incidence of 1 in 10 million adults/year. We report the case of a 24-year-old male patient presenting with the complaints of progressive abdominal distention of 2 months duration. Multiple Detector Computed Tomography (MD-CT) of abdomen revealed a huge enhancing mass in the retroperitoneum abutting the left kidney, and a subsequent CT-guided biopsy and immunohistochemistry confirmed the diagnosis of ganglioneuroblastoma...

BACKGROUND: Introduced more than 20 years ago, laparoscopic pancreatic surgery (LAPS) has not reached a uniform acceptance among HPB surgeons. As a result, there is no consensus regarding its use in patients with pancreatic neoplasms. This study, organized by the European Association for Endoscopic Surgery (EAES), aimed to develop consensus statements and clinical recommendations on the application of LAPS in these patients. METHODS: An international panel of experts was selected based on their clinical and scientific expertise in laparoscopic and open pancreatic surgery...

Brunner's gland adenoma is an extremely rare benign small bowel neoplasm, often discovered incidentally during upper gastrointestinal endoscopy or radiological diagnostics. In few cases, it tends to cause gastrointestinal hemorrhage or intestinal obstruction. We report here our experience with a 47-year-old woman with a Brunner's gland adenoma of more than 6 cm in size, located in the first part of the duodenum and causing gastrointestinal bleeding. Initially, we performed a partial endoscopic resection using endoloop and snare alternatively to prevent severe bleeding...

STAT3 and STAT5 mediate diverse cellular processes, transcriptionally regulating gene expression and interacting with cytoplasmic proteins. Their canonical activity is stimulated by cytokines/growth factors through JAK-STAT signaling. As targets of oncogenes with intrinsic tyrosine kinase activity, STAT3 and STAT5 become constitutively active in hematologic neoplasms and solid tumors, promoting cell proliferation and survival and modulating redox homeostasis. This review summarizes reactive oxygen species (ROS)-regulated STAT activation and how STATs influence ROS production...

Multiple myeloma (MM) is a plasma cell neoplasm that is incurable with conventional therapy. However, the treatment of MM has dramatically changed since the emergence of immunomodulatory drugs and proteasome inhibitors. The improvements in survival are linked to a deeper understanding of the molecular mechanisms of the disease. Thalidomide, although highly active in MM, is associated with considerable toxicity, particularly in older patients. Immunomodulatory drugs (IMiDs) are structural and functional analogues of thalidomide that represent a promising new class of immunomodulators for treatment of a variety of inflammatory, autoimmune, and neoplastic diseases...

We reviewed 97 consecutive cases of myeloid neoplasm with erythroid predominance (MN-EP) between 2000 and 2015. Following 2016 WHO classification, MN-EP patients were classified into four groups. Eight pure erythroid leukemia (PEL) (including t-MN and AML-MRC morphologically fulfilled criteria for PEL) patients had dismal outcomes (median OS: 1 month) and showed more bone marrow fibrosis, worse performance status (PS) and higher serum lactate dehydrogenase (LDH) at diagnosis than the other groups. In the univariate analysis, risks of death in MN-EP patients included the morphologic features of PEL, very poor cytogenetic risk by IPSS-R, bone marrow fibrosis, leukocytosis, anemia, hypoalbuminemia, high LDH, and poor PS...

Chronic lymphocytic leukemia (CLL) is a common, immunophenotypically well-defined mature B-cell neoplasm. Demonstration of more than 5000/μL CD5+ B-cell population with co-expression of CD23, weak expression of CD20, and one type of immunoglobin light chain (either kappa or lambda) is necessary for the diagnosis of CLL. However, CLL with two populations of B-cells expressing both kappa as well as lambda (biclonal) light chains are extremely rare and has not been reported from India. We report two cases of biclonal CLL presented with leukocytosis, typical morphological features, and distinct immunophenotype of CLL...

Mammary analogue secretory carcinoma (MASC) of the salivary glands is a recently described neoplasm of the salivary glands with a characteristic morphology complemented by a specific cytogenetic translocation and gene rearrangements. Although immunophenotypic and cytogenetic differences allow for a more reliable distinction, ultrastructural features can also provide important information about the relationship between MASC, classic acinic cell carcinoma (AciCC), and AciCC intercalated duct cell-predominant variant...
