Adrenal endothelial cyst is a rare entity which has female predilection and usually presents with abdominal pain. Smaller cysts are mostly asymptomatic and detected as incidental finding during surgery. Without biopsy, it is almost impossible to depict the nature of larger cysts as benign or malignant. Herein, we report two such cases. The first case was a 24-year female who presented with a large cyst in the abdomen. The second case was of a 35-year female, who presented with a cystic lesion of right adrenal gland. The clinical, radiological and histopathological findings are discussed. These reports highlight the salient gross, microscopic and immunohistochemical features of these cysts.
