A vesicle or blister >5 mm in diameter.
Large (generally greater than 0.5 cm) fluid-filled blister.
Bullae, blister (vesicle); a large bleb in the skin that contains fluid (serum).
An air- or fluid-filled bubble occurring in the skin or lungs. The latter may be congenital or the result (in adults) of emphysema. Skin bullae are really blisters.
Large blister containing a watery fluid; similar to a vesicle but larger.
Bullae refer to large air-or fluid-filled bubbles that typically appear in the lungs or skin. In young adults, lung bullae are commonly congenital, meaning they are present from birth. Conversely, in later stages of life, lung bullae tend to develop in individuals with emphysema, a condition characterized by the gradual destruction of the air sacs in the lungs. Skin bullae, on the other hand, are significant fluid-filled blisters that can arise from various causes, including the bullous disease pemphigus.
