Bleb

For the protrusion of cell membrane present during apoptosis and cell motility, please see Bleb (cell biology). For the book, see Fred Schneider.

In medicine, a bleb is a large blister (usually approximately hemispherical) filled with serous fluid. Blebs can form in a number of tissues due to different pathologies, including frostbitten tissues, and as a cause of spontaneous pneumothorax. In the lungs, a bleb is a collection of air within the layers of the visceral pleura. In ophthalmology, blebs may be formed intentionally in the treatment of glaucoma.

In geology, mineralogy, and petrology, bleb is a small bubble-like inclusion of one mineral within a larger mineral. An example is a bleb of sylvite within chlorite.
