Büllöz

Büllöz is a term used in medicine to describe the presence of bullae. A bulla is a large blister, typically more than 5 millimeters in diameter, containing clear fluid. These lesions can occur on the skin or mucous membranes.

The formation of bullae can be a symptom of various conditions. In dermatology, bullae can arise from mechanical trauma, such as friction, or from thermal injuries like burns. Certain autoimmune blistering diseases, such as bullous pemphigoid and epidermolysis bullosa, are characterized by the development of bullae. Infections, including some viral or bacterial skin infections, can also lead to bullous eruptions.

In the respiratory system, bullae refer to air-filled sacs that can develop within the lung tissue. These pulmonary bullae are often associated with emphysema, a chronic obstructive pulmonary disease (COPD). They can impair lung function by trapping air and reducing the capacity for gas exchange. In some cases, large bullae can rupture, leading to a pneumothorax, or collapsed lung. The diagnosis and management of bullous conditions depend on the underlying cause and the affected body system.
