pseudomembrane
Pathological tissue layer
A pseudomembrane is a false membrane—a layer of dead cells, fibrin, and inflammatory material that forms on mucous membranes during certain infections.
Unlike true membranes, it lacks the organized cellular structure of living tissue.
Pseudomembranes are characteristic of diphtheria, where a gray coating forms in the throat: The doctor identified the telltale pseudomembrane and suspected diphtheria.
