Primary hepatic origin of a neuroendocrine tumor: A rare case report.

Introduction: Neuroendocrine tumors are mainly located in gastrointestinal tract, pancreas and lungs. The primary hepatic origin of neuroendocrine tumors is extremely rare. Case presentation: A 57-year-old female with a history of cholecystectomy presented to our hospital for right upper abdominal pain lasting for 2 months. Abdominal computed tomography revealed a large exophytic soft-tissue mass in the left liver lobe. Tumor markers were within the normal range. Octreoscan confirmed the primary hepatic origin of neuroendocrine tumor. The patient underwent left hepatic resection. Pathological and immunohistochemical examination of the resected specimen showed a well-differentiated grade 2 neuroendocrine tumor. Clinical discussion: Primary hepatic neuroendocrine tumors represent rare hepatic tumors. These tumors may occur at any age with an average of 50 years. Diagnosis algorithm includes two key steps: firstly, the confirmation of the endocrine nature of the tumor and secondly the confirmation of its primary nature. Conclusion: Neuroendocrine tumors are a very rare entity. The primary hepatic location is exceptional. The diagnosis is based on pathological and immunohistochemical examination as well as the result of the octreoscan.

Littoral Cell Angioma of Spleen: A rare case report.

Introduction: Spleen's Littoral Cell Angioma is a rare benign vascular tumor. The main clinical presentation is isolated splenomegaly. Case presentation: we present the case of a 37 years old male patient who suffers from chronic pain in the left hypochondrium.The abdominal examination finds a painful splenomegaly related to a biological bicytopenia. The CT Scan shows a 32 cm splenomegaly.An exploratory laparotomy with splenectomy was performed. The histological and immunohistochemical study confirmed The final diagnosis of Littoral Cell Angioma. Clinical discussion: Isolated splenomegaly of unknown etiology is the main clinical sign. Splenectomy is required for a diagnostic purpose and substratum for histological study. Conclusion: Littoral Cell Angioma of the Spleen is a rare benign vascular tumor, however it should be highlighted by clinical and radiological features, the definitive diagnosis is made upon histological study.

Mesenteric cystic lymphangioma in an adult: An unusual case report.

Introduction: Cystic lymphangioma is a benign malformation tumor of the lymphatic system. Its location is variable, and mesenteric localization remains extremely rare. Case presentation: We describe a rare case of cystic lymphangioma of the mesentery in a 26 years old woman. The diagnosis was suspected following an abdominopelvic computed tomography (CT) and magnetic resonance imaging (MRI), showing a large polylobulated cyst in contact with the stomach, the tail of the pancreas, the spleen, and the antero-external cortex of the left kidney. The patient underwent laparoscopic surgery with a pericystectomy. Pathological examination confirmed the diagnosis of cystic lymphangioma of the mesentery. The patient's postoperative recovery was uneventful. After a Follow up of one year after surgery, there was no evidence of recurrence. Clinical discussion: Cystic lymphangioma of the mesentery is a benign malformation tumor of the lymphatic system. Its clinical aspects are very polymorphic; the diagnosis is evoked by radiological imaging but requires pathological confirmation. Surgery is the gold standard in the management of this pathology. Conclusion: We highlight the importance of radical surgical resection to avoid Cystic lymphangioma complications and minimize the recurrence risk.
