RESUMEN
A 74-year-old woman with end-stage renal disease presented with clinical symptoms of encapsulating peritoneal sclerosis 2â years after switching from peritoneal dialysis to haemodialysis. Imaging revealed a large cystic structure in her abdomen and her final diagnosis was made by exploratory laparotomy. A 10â cm×15â cm fibrous rind was excised from the peritoneum and the patient was subsequently started on tamoxifen 20â mg daily and prednisone 20â mg daily. Given her reduction in clinical symptoms and concerns about the long-term effects of corticosteroids, prednisone was tapered and she remained on tamoxifen monotherapy. 1â year postsurgery, she presented with symptoms of nausea, vomiting and anorexia. A repeat CT of the abdomen confirmed a recurrence of encapsulating peritoneal sclerosis. Prednisone and tamoxifen were restarted at increased dosages of 25 and 40â mg daily, respectively. The patient's symptoms were ameliorated within 2â weeks of drug therapy modification.
