Abstract

DOEGE-POTTER syndrome is a paraneoplastic syndrome in which hypoglycemia results from tumors producing insulin-like growth factor (IGFII). It is most often the solitary fibrous tumor of the pleura. These are rare and may be discovered incidentally, during non-specific respiratory symptoms or during hypoglycemia. Hypoglycemia occurs in large tumors and disappears after surgery, which is the treatment of choice, allowing permanent cure in the majority of cases.

Highlights

  • DOEGE-POTTER syndrome is a rare paraneoplastic syndrome, initially described in 1930 by Doege and Potter and mainly involving solitary pleural fibrous tumors

  • We report the case of a 61-year-old patient followed in Pasteur Hospital for a local recurrent malignant neurofibromatous tumor presenting recurrent hypoglycaemia with hypersecretion of insulin-like growth factor

  • We report the case of a 61-year-old patient followed for solitary fibrous tumor of the pleura who underwent video-thoracoscopic resection in 2009, remained under surveillance

Summary

Introduction

DOEGE-POTTER syndrome is a rare paraneoplastic syndrome, initially described in 1930 by Doege and Potter and mainly involving solitary pleural fibrous tumors. We report the case of a 61-year-old patient followed in Pasteur Hospital for a local recurrent malignant neurofibromatous tumor presenting recurrent hypoglycaemia with hypersecretion of insulin-like growth factor. Hypoglycemia is an infrequent complication of these tumors, via an insulin-like growth factor secretion mechanism, and may be indicative of it. These tumors have a low rate of malignancy, around 12% to 15%.
