Adrenal Schwannoma. Report of two cases.

Adrenal tumours are frequently incidental discoveries, and their therapy is a subject of controversial discussions. Herein we describe two cases of adrenal schwannoma discovered during autopsy. The accidental observation of two benign schwannomas of the adrenal gland on asymptomatic patients led to the hypothesis that the real frequency of this type of lesion was underestimated. Furthermore, the adrenal origin of the superior retro-peritoneum schwannomas represents a diagnostic hypothesis to be considered when the original structure of the neoplasia can't be established.
