Hyaline or amyloid‐like substances may be seen in several oral lesions. Some of these originate from epithelial cells and some from connective tissue components. In this study, amyloid‐like material causing gingival enlargement in three patients, with eyelid involvement in two, was examined using histochemistry, immunohistochemistry and electron microscopy. These accumulations did not share the classical features of amyloid such as green birefringence under polarized light after Congo red staining. Our findings suggest that epithelial degeneration plays an important role in the pathogenesis of these amyloid‐like accumulations. These substances may be the result of defective amyloidogenesis and our cases may represent an oral counterpart of ligneous conjunctivitis or colloid milium of the skin.
