A large number of Charcot-Böttcher crystalloids were observed in tesicular Sertoli cells of a 24 year-old man. The crystalloids were stained positively with coupled tetrazonium method and with Coomassie brilliant blue. However, histochemical methods for lipids, polysaccarides and nucleic acids failed to stain the structure. The crystalloids consisted of closely packed Parallel arreys of dense filaments 9-11 nm wide. These filaments were frequently continuous with cytoplanmic intermediate filaments. An association of filamentous elements and a pair of rough endoplasmic reticulum was occasionally found in perikaryal cytoplasm of the Sertoli cells. It is suggested that the crystalloids are proteinaceous in nature and are formed by the aggregation of intermediate filaments.
