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.

Giant parathyroid carcinoma: Diagnostic, difficulties and therapeutic strategies: A case report.

INTRODUCTION: Parathyroid carcinoma is a very aggressive malignant tumor. It is mostly revealed by clinical primary hyperparathyroidism. CASE PRESENTATION: We report a rare case of parathyroid carcinoma in a 61-year-old-male patient who presented with a painless right-sided cervical tumefaction of hard consistency associated with cervical lymphadenopathy. Cervical ultrasonography showed a right parathyroid mass with intimate contact with the homolateral thyroid lobe. A parathyroidectomy enlarged to the adjacent thyroid parenchyma with a selective neck dissection level VI was performed. CLINICAL DISCUSSION: The clinical presentation is most often manifested with clinical features of primary hyperparathyroidism associating bone disorders. Surgery remains the treatment of choice. The benefit of adjuvant treatments is controversial and remains to be evaluated. CONCLUSION: Parathyroid carcinoma is a rare tumor. This rare entity is often presented with clinicobiological features of severe primary hyperparathyroidism.

Surgical management of gallbladder carcinosarcoma: A case report and review of the Literature.

INTRODUCTION: Gallbladder Carcinosarcoma is a rare and fatal cancer characterized by the presence of a combination of a cancerous epithelial and mesenchymal components. PRESENTATION OF CASE: We present the case of a 66 years old patient with a carcinoma gallbladder carcinoma who received a surgical treatment. The histological assessment revealed two histological components consisting of an adenocarcinoma and a spindle cell sarcoma compatible with the carcinosarcoma. DISCUSSION: This cancer is known to be extremely severe in that less than 100 cases have been documented in international medical review of literature. surgical treatment remains the only cure for gallbladder carcinosarcoma, The prognosis of this disease is extremely poor because it normally presents at advanced stages. CONCLUSION: We present an extremely rare example of carcinosarcoma, and its attributes might be suggestive of a greater malignant potential. Consequently, the later the diagnosed worse is the prognosis.
