Chromophobe renal cell carcinoma: A case report and literature review.

INTRODUCTION: Chromophobe renal cell carcinoma, a distinct subtype of renal cell carcinoma (RCC) with characteristic light microscopic, histochemical, and ultrastructural features, typically has a favorable clinical course. PRESENTATION OF CASE: A 45-year-old femele presented with abdominal pain. A physical examination found a palpable mass in the left upper quadrant of the abdomen. A CT scan of the abdomen showed a heterogeneously enhancing mass, with necrosis and calcifications contents betwen the liver and the right kidney. she underwent surgical resection. Partial nephrectomy was performed. Pathological diagnosis was Chromophobe renal cell carcinoma. DISCUSSION AND CONCLUSION: Chromophobe RCC is a rare variety of kidney neoplasm that has recently been better characterized from a molecular and genetic perspective. Overall, it is considered to have a better prognosis, and is associated with earlier stage tumors and longer overall survival compared with clear cell RCC.

Non-functional retroperitoneal paraganglioma: A report of case with literature review.

INTRODUCTION: Retroperitoneal paragangliomas are rare tumors, they arise from ganglia along the sympathetic and parasympathetic chain. We report a rare case of a non functional paraganglioma in whom surgical resection was performed. PRESENTATION OF CASE: A 35 years-old female presented with chronic abdominal pain, A contrast magnetic resonance imaging (MRI) of abdomen showed a well-defined Left latero-aortic cystic retro-peritoneal surgical resection using laparotomy was performed, The patiente recovered well and was discharged three days after surgery. Histological examination and immunohistochemical revealed a retroperitoneal paraganglioma. DISCUSSION AND CONCLUSION: Non-functioning retroperitoneal paragangliomas are rare and are most often Isolated. Radiological techniques including, Contrast-enhanced computed tomography (CT) and Magnetic resonance imaging (MRI) are useful for identifying and locating retroperitoneal paragangliomas. surgical excision is still the most effective treatment when it possible.

A gastrointestinal stromal tumor of stomach presenting with an intratumoral abscess: A case report.

INTRODUCTION: Gastrointestinal stromal tumors (GISTs) are the most common mesenchymal tumors in the gastrointestinal tract, GISTs of the stomach presenting as an intratumoral abscess are extremely rare, which necessitates emergency surgery, we report a case of a stomach GIST developing an intratumoral abscess, in whom emergency surgery was performed. PRESENTATION OF CASE: A 68-year-old man presented with severe abdominal pain and a fever. Laboratory data showed an elevated white blood cell count and C-reactive protein level. Computed to mography scan showed a 15 × 10 cm cystic mass adjacent to greater curvature of the stomach, which contained air. Emergency laparotomy revealed A giant cystic gastric mass was observed. Sleeve gastrectomy were performed. Immunohistochemically, the tumor was diagnosed as a Gastric high risk GIST,and imatinib mesylate was initiated, The patient had an uneventful postoperative course and remains well. DISCUSSION AND CONCLUSION: Such rare cases can be diagnosed and treated properly with careful clinical evaluation, surgical resection and adjuvant chemotherapy with imatinib mesylate is still the mainstay and most effective treatment for GISTs to date.

Phytobezoar: An unusual cause of small bowel obstruction.

Phytobezoars are concretions of indigested fruit and vegetables fibers in the gastrointestinal tract. The past of gastric surgery is most common risk factor of phytobezoar. We present the case of a 39-year-old female was admitted to the emergency department and who presented with small bowel obstruction due to phytobezoar, her past medical history was marqued by truncal vagotomy and simple suture recurrent perforated gastric ulcer 15 years earlier. Her postoperative recovery was uneventful.

Primary appendiceal Burkitt's lymphoma presenting as acute appendicitis: An extremely rare case report and review of the literatture.

Primary lymphomas of appendix are extremely rare tumors. The incidence is 0.015% out of all gastrointestinal lymphomas; furthermore, limited data is available in literature. The appendiceal neoplasms are most commonly presented as acute appendicitis followed intestinal obstruction, intussusception or perforation. We present a case of a 22 year-old male patient who presented with acute appenditis and underwent emergency laparotomy. On abdominal exploration, swollen and enlarged appendix measured 3cm was present for which appendectomy were performed. The histopathological examination of appendectomy specimen revealed a Burkitt's Lymphoma. The patient received R-COPADEM protocol of chemotherapy. Primary gastrointestinal lymphoma is a extremely rare neoplasm without guidelines for therapy.
