Cysts of the adrenal gland: Revision of a 15-year experience

Ten specimens of adrenal cyst resected during the period 1984-1999 were re- examined. Thorough examination of multiple sections and the use of immunohi stochemistry allowed to change the recorded diagnosis in 8 cases: three epi thelial cysts and five pseudocysts were redefined as endothelial cysts. All 10 cysts were of the endothelial type. A synthetic review of the current k nowledge about the pathogenesis, the classification and the clinical aspect s of this rare disease is presented.
