The structure of IGF-2, responsible for the hypoglycemia associated with Doege–Potter syndrome

Doege–Potter syndrome (DPS) is a paraneoplastic syndrome[1] in which hypoglycemia is associated with the presence of one or more non-islet fibrous tumors in the pleural cavity. The hypoglycemia is the result of the tumors producing insulin-like growth factor 2.[2] The syndrome was first described in 1930, by Doege[3] and Potter working independently;[4] the full term "Doege–Potter syndrome" was infrequently used until the publication of a 2000 article[5] using the eponym.[6]

DPS is rare (as of 1976, less than one hundred cases were described[7]), with a malignancy rate of 12–15%. Actual rates of hypoglycemia associated with a fibrous tumor are quite rare (a 1981 study of 360 solitary fibrous tumors of the lungs found that only 4% caused hypoglycemia[8]), and are linked to large tumours with high rates of mitosis.[9] Removal of the tumor will normally resolve the symptoms.[1][9]

Tumors causing DPS tend to be quite large;[10] in one case a 3 kg (6.6 lb), 23×21×12 cm (9.1×8.3×4.7 in) mass was removed, sufficiently large to cause a collapsed lung.[5] In X-rays, they appear as a single mass with visible, defined borders, appearing at the edges of the lungs or a fissure dividing the lobes of the lungs.[10] Similar hypoglycemic effects have been related to mesenchymal tumors.[6]
