Mast cells in elastic cartilage of the human epiglottis.
Light and transmission electron microscopy revealed in the elastic cartilage of the human epiglottis the presence of mast cells. Cytoplasmic granules of these cells contain characteristic cylindrical bodies, whose texture is different from that found in cytoplasmic granules of mast cells from other sites. The presence of mast cells in elastic cartilage, described for the first time, and the different substructure of their cytoplasmic granules, is considered as another proof of the heterogeneity of that cell type.
