Inspissated secretions

Last revised by Yuranga Weerakkody on 14 Sep 2021

Inspissated secretions refers to thickened secretions with increased viscosity within ducts or body cavities (usually nasal, paranasal sinus, oral or ductal) that usually become thickened by dehydration (typically a chronic process). The secretions can then cause obstruction to respective airways or ducts. Some inspissated secretions may become calcified resulting in dystrophic calcification.
