title: Large Retroperitoneal Mass Diagnosed as Adrenal Chronic Expanding Hematoma.
abstract: Chronic expanding hematoma is defined as a structure with central mass of blood and granulation tissue encapsulated with dense fibrous membrane that slowly grows over a month. We report a case of a 67-year-old man with left adrenal chronic expanding hematoma who underwent surgical resection after 7-year surveillance, presenting natural history of an adrenal chronic expanding hematoma.
