A case of endothelial cyst of the adrenal gland / 대한내과학회지

Adrenal cysts are rare lesions usually discovered incidentally during surgery, or at the time of autopsy. Most adrenal cysts are generally asymptomatic and small, less than 10 cm in diameter. When adrenal cysts enlarge sufficiently, they cause pain and gastrointestinal disturbances or become palpable. When cystic lesions in upper abdomen are found, many cystic lesions such as hepatic, splenic, renal and pancreatic cysts should be considered. It's difficult to differentiate between benign and malignant lesions. Usually these cystic lesions have been excised to rule out malignancy. Herein we report a case of adrenal endothelial cyst which was detected in a 63-year-old female patient during a routine health examination by ultrasonography.

Endothelial Cyst of the Adrenal Gland: Report of a case

Adrenal cysts are rare lesion that usually present themselves as an incidental finding during surgery, or at the time of autopsy. The cysts are usually small, seldom exceeding 10cm in diameter, and are generally asymptomatic. However, they present a difficult problem in differentiation between benign and malignant lesions of the adrenal gland. In the differential diagnosis, other cystic lesions of the upper abdomen must also be considered, including hepatic, splenic, renal and pancreatic cysts. Herein we report a case of endothelial cyst of lymphangiomatous type of the adrenal gland which was detected in a 44-year-old male patient during a routine health examination by ultrasonography as a pancreatic pseudocyst. Gross examination revealed multiple separate but continuous cysts, measuring 10.6x8x7cm in dimension. Within the wall, compressed adrenal cortex was noted. Microscopically, fibrous wall containing hypertrophied smooth muscle lined by endothelial cells was also noted. We reviewed literatures of the adrenal cyst and report a case.
