[Two cases of sellar chordomas. Ultrastructural and histochemical study (author's transl)].

Two cases of sellar chordomas are reported, with ultrastructural and histochemical study. The embryological origin and the histochemical data are discussed. The question of chondroid chordomas is evoked and the results of the ultrastructural study are interpreted on the basis of the cases hitherto reported. Special attention is called to the methods for the detection of polysaccharides by electron microscopy in such proliferations. Tissue culture seems to be able of providing a good information as to the secretory activity of the chordomas located at the skull base.

[Immunohistochemical study of plasmocytes and T-lymphocyte subpopulations in Hashimoto's thyroiditis].

In Hashimoto's thyroiditis, there is a diffuse interfollicular infiltration of lymphocytes and plasmocytes and lymphoid collections with germinal centers. Eleven cases of Hashimoto's disease were studied with immunocytochemical methods for characterization of intracytoplasmic immunoglobulins (IgA, IgG, IgM, Kappa and lambda light chains). Most of the cells are plasmocytes stained positively for intracytoplasmic IgG; IgA positive cells were less frequent and IgM positive cells are rare. Kappa positive plasma cells are more numerous than lambda positive cells in the germinal centers and the interfollicular infiltration. By an indirect immunofluorescence technique in frozen tissue, we have studied with four monoclonal antibodies (OKT3, OKT4, OKT8, B1) the T cells subsets populations in two cases.
