Abstract: Nephrotic syndrome (NS) is a pivotal manifestation of glomerular injury associated with various types of neoplasms. It may either precede or act as the presenting feature of the disease, whereas membranous nephropathy (MN) is a major phenotype of paraneoplastic glomerulopathies. However, there is a lack of information regarding the remission from paraneoplastic NS due to MN in patients who achieve favorable long-term survival after the successful removal of malignant tissue. We, herein, describe a case of biopsy-proven MN in a 65-year-old male patient with bronchogenic carcinoma, which was found during the systemic workup for concurrent NS. He was successfully treated with thoracoscopic left lower lobectomy and achieved a complete remission from NS at approximately 10 months after radical surgery. In 10 years of follow-up, there has been no recurrence of the pulmonary cancer and the patient is doing well with no relapse of NS, despite having never received treatment with any type of immunomodulating agent. Several concerns, including diagnostic management and therapeutic strategies for paraneoplastic NS, are discussed.
