A 36-year-old woman presented with a 3-year history of pruritic erythema and scaling on the trunk and extremities.Dermatological examination revealed ill-defined light pink macules with white lamellar scales on the chest,abdomen and buttocks.Histologically,there was a focal mononuclear cell infiltrate in the superficial dermis,with the epidermotropism of some cells and mild atypia of epidermotropic cells,as well as an interstitial mononuclear cell infiltrate and mild deposition of mucin between the collagen fibers in the middle dermis.CD3 and CD4 were expressed by scattered mononuclear cells infiltrating the upper and middle dermis.Based on these data,the patient was diagnosed with interstitial granuloma fungoides.

Objective A previously reported female diagnosed with type A insulin resistance syndrome bearing a heterozygous missense mutation of R1174W in the insulin receptor gene was followed for 7 years since the age of 16 years. Methods Five-hour oral glucose tolerance tests (OGTT) were done on baseline, the 3rd, 6th and 7th year respectively, with serum insulin and C-peptide measured at the same time points. Areas under of curve (AUC) of glucose, insulin and C-peptide were compared between the years.Acute insulin response (AIR) was determined at baseline and the 7th year. The dose response were insulin secretion rates at each time point during OGTT being plotted over the corresponding glucose levels, and the slopes of which quantified the insulin secretion responding to glucose. Results The follow up data showed that the glucose metabolism of the subject did not deteriorate over time with yearly glycosylated hemoglobin A1c (HbAlc) being normal (4.6%-5.5%), and hyperinsulinemic hypoglycemia was a persistent phenomenon observed at 4-5 hours post-load. The fasting and AUCs of serum insulin and C-peptide tended to decline without simultaneously increase of those of plasma glucose. The AIR decreased by 56% as compared to baseline. The dose response curves shifted downward as years went by. Conclusions It supports that with the alleviation of physiological insulin resistance after puberty, the gross hyperinsulinemia tends to ameliorate, and β-cell secretion does not deteriorate over time as glucose homeostasis maintains.
