Unexplained refractory iron-deficiency anaemia in a 41-year-old woman

The clinical and instrumental findings revealed a case of autoimmune polyendocrine syndrome (APS) type 3B+C in a 41-year-old Caucasian woman with unexplained refractory iron-deficiency anaemia secondary to autoimmune atrophic gastritis and a long-term history of two different autoimmune diseases-Hashimoto's disease and vitiligo. Indeed the occurrence in the same patient of three or more autoimmune diseases defines APS. The first classification of APS was suggested by Neufeld and Blizzard in 1980 and it included four main types of APS on the basis of clinical features. The only case of APS type 3B+C was described by Amerio et al in 2006.
