A 31-year-old woman experienced tetany and was diagnosed with Hashimoto thyroiditis and hypoparathyroidism. At 33 years of age, her renal function gradually decreased. At 39 years of age, she moved to our hospital and was diagnosed with tubulointerstitial nephritis by renal biopsy. Simultaneously, she was diagnosed with Sjögren’s syndrome by autoantibodies and salivary gland biopsy. At 40 years of age, based on hypoglycaemia and eosinophilia, she was suspected of adrenal insufficiency, and was diagnosed with primary adrenal insufficiency by both corticotropin stimulation and corticotropin-releasing hormone stimulation test. She was diagnosed as autoimmune polyglandular syndrome (APS) (Hashimoto thyroiditis and possible primary adrenal insufficiency) as well as primary hypoparathyroidism and Sjögren’s syndrome, which are very rarely complicated in APS-2. Therefore, in this patient, it was helpful to pay attention for new onset of other autoimmune diseases.
