AN ADULT CASE OF RETROPERITONEAL CAVERNOUS LYMPHANGIOMA

Cavernous lymphangiomas commonly found in the neck and axilla of the infant, but rarely in the retroperitoneal in the adult. We report a rare case of retroperitoneal cavernous lymphangioma in a 59-year-old female. She was referred to the hospital for investigation of an abdominal tumor which was found incidentally at another hospital. She was symptom-free and laboratory study revealed no abnormality though an ultrasonography showed a right retroperitoneal polycystic tumor which compressed the right kidney and gallbladder. On operation, the polycystic tumor measuring 16.3×11.5×5.2cm in size tightly adhered to the right renal artery which was feeding the tumor. The tumor was completly excised from the retroperitoneal space anterior and inferior to the right kidney. The final pathologic diagnosis was cavernous lymphangioma. No malignat findings were noted.
