Retroperitoneal ; Teratoma

Retrospective study on the clinical and paraclinical features and results of treatment of some retroperitoneal tumors in 119 patients has found that the clinical symptoms, in generally were atypical. It is not difficult to diagnose the retroperitoneal tumor when combining many methods such as ultrasound, angiography, CT scanner, tumor markers but it is difficult to diagnose each kind of tumor.

Schwannoma also referred to as neurilemmoma, neurinoma, and perineural fibroblastoma, is an encapsulated nerve sheath tumor consisting of two components :a highly ordered cellular component (Antoni A area) and a loose, myxoid component (Antoni B area). It is usually solitary and may be benign or malignant, solid or cystic, encapsulated or diffuse. It is rarely occur in the retroperitoneal space. The term cellular Schwannoma is indicative of a Schwannoma composed predominantly of Antoni A type tissue. We report one case of retroperitoneal with brief review of literatures.

Neurilemmomas are tumors of the neurilemmoma or nerve sheath of Schwann. They rarely occur in the retroperitoneal space. It is usually solitary and may be benign or malignant, solid or cystic, encapsulated or diffuse. We report 2 such cases and discus the clinical and pathological features.

Primary retroperitoneal neoplasms are rare, accounting for only 0.1-0.2% of all malignancies. Retroperitoneal location of leiomyoma are uncommon. Less than 2% of retroperitoneal tumors are leiomyomas. We report a case of huge retroperitonal leiomyoma mimicking solid adnexal mass with brief literature review.

Primary retroperitoneal cavernous hemangioma is a very rare benign neoplasm. A retroperitoneal hemangioma may be detected accidentally or be symptomatic due to local compression on adjacent structures. We reported on the diagnosis and treatment of a patient with PRCH with a subtle clinical presentation and atypical findings on computed tomography imaging. The patient presented with right hypochondriac discomfort for one month duration. Computed tomography of the abdomen revealed a huge mass arising from right lobe of liver which was compressing the surrounding structures. Intraoperatively there was a huge cystic like mass arising from the retroperitoneum which had clear margin with the adjacent structures. The tumour was successfully excised with an intact capsule and histopathological examination revealed a cavernous hemangioma.
