title: Crystalloid structure in adrenocortical adenoma.
abstract: The presence of crystalloid structures was demonstrated in the cytoplasm of a huge adrenocortical adenoma ultrastructurally. The crystalloids were classified into four types, and they differed from those of spironolactone bodies or intramitochondrial bodies in their size and shape. The structures of the crystalloids resembled the crystalloids of Reinke in the Leydig cells of the testis. Reports on intracytoplasmic crystalloids are rare in the tumors of the adrenal cortex.
