ABSTRACT
Bullae formation on a cystic background is still not described thoroughly. This clinical case aims to improve this situation and describes the combination of multiple cysts with vascular malformation, giant bullae (2/3 of the left hemithorax and 1/2 of the right hemithorax) with suppuration in a 50-year-old smoker. Before surgery, treatment for chronic obstructive lung disease (COPD) was administered without a positive outcome. Bullectomy was subsequently conducted and histopathological data revealed vascular malformation causing microinfarctions in pulmonary parenchyma, cystic degeneration and tuberculosis. Although it became possible to establish a final diagnosis due to histology, the need for surgical treatment was clear from clinical and x-ray evidence. Such instances as the one presented in this case report should assist with improving our knowledge about bullae in combination with cysts in the lungs because they provide additional context in a clinical setting.
