L12_BULLOUS

vesiculobullous skin disease: Skin diseases characterized by local or general distributions of vesicles and bullae (i.e. blisters). Both vesicles and bullae are fluid-filled lesions, distinguished by size (vesicles being less than 5–10 mm and bullae being larger than 5–10 mm). Vesiculobullous diseases are classified according to the site and mode of blister formation. Lesions can appear spontaneously or be precipitated by infection, trauma, or sunlight. Etiologies include immunologic and genetic factors. In the case of vesiculobullous diseases which are also immune disorders, the term immunobullous is sometimes used.
