[Crystalline morphology of trihexosylceramide deposits characteristic of Fabry's disease (notably the rheumatic form)].

: This paper deals with the various crystalline aspects of the ceramide trihexoside (CTH) inclusions, in the synovial tissue essentially. A basic classification is proposed and uncommon examples are illustrated. Image processing confirms the membrane-like structure of CTH inclusions and corroborates the proposed classification.
