Low-grade fibromyxoid sarcoma in a child presenting as a popliteal fossa swelling

Popliteal fossa masses are rare in paediatric age group. Even rarer are the malignancies of this area. Low-grade fibromyxoid sarcoma (LGFMS) is a distinctive variant of fibrosarcoma. It is a rare tumor with benign histologic appearance but high metastasizing potential. We describe an 11-year-old child with a popliteal fossa mass, which was excised, and histopathological report revealed LGFMS

Gallbladder polyp: A rare lesion in pediatric population

An 11-years-old girl with a polyp in the gallbladder is reported. Laparoscopic cholecystectomy was curative

Sacrococcygeal teratoma associated with hindgut duplication: A case report & review of literature

The index case report describes a previously unreported coexistence of sacrococcygeal teratoma and a tubular duplication of the rectum. The child presented with a large sacrococcygeal mass. He was treated with pre-operative chemotherapy to reduce the bulk of the tumor and subsequently underwent surgical resection. Exploration surprisingly revealed an additional long tubular duplication of the rectum, which did not share any lumen with the parent gut. The duplication cyst and the residual tumor were excised. The histopathology report confirmed residual mature teratoma and the duplication cyst. Relevant literature is reviewed

Ovarian cysts and tumors in infancy and childhood

Aim: Review of the clinical presentation, types (histology), and stages of presentation and overall outcome of ovarian tumors. Materials and Methods: This is a retrospective study. Forty nine girls from 3 days to 12 years were included in the study. Results: Fourteen girls had benign and thirty three had malignant ovarian tumors. One girl had bilateral ovarian non-Hodgkin lymphoma. Dysgerminoma (40%) was the commonest malignant tumor followed by malignant teratoma (16.6%). Conclusion: Pain and abdominal lump are the most common modes of presentation. Prognosis depends on the size of the tumor, stage and histology of the tumor. Conservative surgery should be the aim. Multidisciplinary management gives good prognosis

Cancer immunotherapy : a promising dawn in cancer research

Cancer is a highly proliferative disease, which is caused due to the loss of regulation of cell cycle and apoptosis, DNA damage, faulty repair system etc. The cancer microenvironment plays a pivotal role in disease progression as they contain different types of innate and adaptive immune cells. The most important molecules that establish a correlation between inflammation, innate immunity, adaptive immunity, and cancer are the molecules released by inflammatory cells in cancer microenvironment. These molecules secreted by the immune cells, which might activate a pro-tumorigenic and anti-tumorigenic response in cancer. In inflammatory microenvironment, the equilibrium state of immunosuppressive and immunostimulatory signals are important in tumor suppression. The immunotherapeutic approaches could be more effective in cancer treatment. However, advancement in immunobiology and cancer are improving the prospects of immunotherapy alone and/or in combination with the conventional therapies. Thus, the review attempts to highlight a promising and futuristic immunotherapeutic approach in combination with conventional treatment modalities

Synthesis of Polyfunctionalized Pyrroles via a Tandem Reaction of Michael Addition and Intramolecular Cyanide-Mediated Nitrile-to-Nitrile Condensation

A new approach for the synthesis of tetrasubstituted/functionalized NH-pyrroles from <i>gem</i>-diactivated acrylonitriles and TMSCN has been developed. The strategy utilizes the generation of <i>vic</i>-dinitrile via Michael addition and cyanide-mediated nitrile-to-nitrile cyclocondensation, which proceed in tandem guided by manifold roles of “CN”. An extended application to the production of fused pyrrole has also been realized
