[Paraneoplastic ichthyosis. Ultrastructural study].
A case of ichthyosis in association with bronchial carcinoma is studied by electron microscopy. Keratohyaline granules are always present in only one layer; variable in size but often reduced upon short tonofilament bundles, they are structurally normal. This suggested a reduced synthesis of a normal keratohyalin, different from the synthesis of an abnormal few spongy keratohyaline in autosomal dominant ichthyosis vulgaris.
