Retroperitoneal Tumor, a Primary Cavernous Hemangioma: A Case Report.

The diagnosis of primary retroperitoneal cavernous hemangiomas is extremely rare in clinical practice. Only a few cases have been reported. Due to the lack of specific radiological features, their diagnosis is uncommon. They are usually found incidentally or after symptoms as a consequence of complications. Adult retroperitoneal cavernous hemangiomas are extremely rare. This is a report of a rare case of a primary retroperitoneal cavernous hemangioma in a 45-year-old male patient discovered after acute appendicitis. A histopathological examination is conducted following total surgical resection to confirm the diagnosis.
