Abnormal skin morphology Abnormal cutaneous elastic fiber morphology 2016-10-15T12:16:20Z Any structural anomaly of the elastic fibers of the skin. Elastic fibers are the essential extracellular matrix macromolecules comprising an elastin core surrounded by a mantle of fibrillin-rich microfibrils. Abnormal cutaneous elastic fibre morphology Elastic fibers help the skin return to its normal configuration after being stretched or deformed. The elastic fibers consist of two components: microfibrils and matrix elastin. The microfibrillar component amounts to only 15% of the elastic fiber, whereas the amorphous, electron-lucid elastin makes up 85% of the fiber. In light microscope sections that are routinely stained, elastic fibers are inconspicuous. With special elastic tissue stains, such as orcein or resorcin-fuchisin, or in plastic-embedded sections they are found entwined among the collagen bundles [PMID:21738362].
