Fig 2 (A) The cut section of the resected tumor, which was believed to have originated from the visceral pleura of the left lower lobe. (B) Immunohistochemical staining of insulin-like growth factor II (IGF-II). Many tumor cells were positive for IGF-II antibody (original magnification, ×400). (C) Western immunoblot of serum IGF-II. Lane 1: recombinant IGF-II. Lane 2: our patient (preoperative). Lane 3: our patient (postoperative). Lane 4: another non-islet cell tumor hypoglycemia (NICTH) patient. Lane 5: normal subjects. Lane 6: another NICTH patient. Western immunoblot analysis shows that a large amount of high molecular weight IGF-II (20-kDa) was detected in the preoperative serum, whereas the amount of normal IGF-II (7.5-kDa) was increased in the postoperative serum.

Fig 3 Clinical course of plasma glucose level before and after surgery. Glucose supplementation of 10 g/hr was necessary for maintenance of the plasma glucose level during the preoperative fasting period. Shortly after tumor excision, the plasma glucose level was stable with glucose supplementation of 3.4 g/hr. (BS = blood sugar.)
