Recurrent pneumothorax, which frequently results from underlying bullous disease, infections, or other lung pathology, can present serious diagnostic and treatment issues. We report the case of a 38-year-old woman with recurrent right-sided pneumothorax. Following VATS bullectomy a pulmonary meningothelial-like nodule (PMLN) was discovered in the resected specimen. Progesterone receptor (PR) positivity and patchy CD56 staining were among the immunohistochemistry (IHC) results; HMB45, MNF, and oestrogen receptor (ER) were negative. Our case emphasises the value of thorough pathological examination in determining uncommon reasons for recurrent pneumothorax and the therapeutic ramifications of such.
