Pathology dictionary -
Spongiosis is a word pathologists use to describe the microscopic look of squamous cells that have been pushed apart by fluid.
Many body surfaces, including the skin and the inside of the mouth are covered by special cells called squamous cells. These cells normally stick tightly together to protect the tissue below. If these cells become injured, fluid can get in between the cells.
Spongiosis is not a diagnosis because it can be caused by many different types of injuries or diseases. Spongiosis is commonly seen in inflammatory conditions of the skin.
