Abstract:
This case report highlights a rare association between membranous nephropathy (MN) and papillary thyroid carcinoma (PTC) in a 66-year-old female with progressive renal dysfunction. Following a confirmed diagnosis of MN with negative phospholipase A2 receptor (PLA2R) staining, imaging revealed a thyroid malignancy, and total thyroidectomy led to clinical improvement, suggesting a paraneoplastic mechanism. This case underscores the importance of oncologic screening in MN patients and the need for further research into the pathophysiological links between MN and thyroid cancer.
