[Adrenal gland cysts. Case reports and potential complications--review of the literature (author's transl)].

Adrenal cysts are rare, mostly harmless, processes, either congenital inborn or acquired by regression, bleeding, infection and tumor. In the case of endocrine dysfunction with arterial hypertension and local expansion with perforation into the retroperitoneal, peritoneal and pleural cavity, purulence, bleeding and vasal obstruction complications are serious. In the differential diagnosis carcinoma of the kidney and the adrenal gland should be excluded.
