glycogen and Keratosis

This report describes a rare case of glycogenic acanthosis (GA) located on the tongue of a 72-year-old man. The patient presented with a white plaque that had been on the right side of the tongue for 5 years. Histologically, the lesion was characterised by thickened squamous epithelium with abundant intracellular glycogen deposits. No epithelial dysplasia was noted. This is the first report of GA involving the tongue. This benign condition should be added to the large number of lesions responsible for leukoplakia in this anatomical location.

This paper deals with the histological and ultrastructural findings in a case of the Sézary syndrome. The striking nuclear and cytoplasmic features of the Sézary cell are illustrated, and the similarities of this cell to the mycosis fungoides cell are once more stressed.
