A 62-year-old Taiwanese woman with a history of schizophrenia presented to our emergency department with a brain tumour causing her headaches. She was admitted due to severe anaemia, and after further investigation, the patient was discovered to have pernicious anaemia and autoimmune thyroiditis\u2014consistent with the diagnosis of \u00a0polyglandular autoimmune syndrome IIIb. Her underlying primary psychiatric diagnosis was then questioned. The diagnosis of her endocrinopathies were likely delayed for many years due to the psychiatric disorder which may have been due to her long-standing autoimmune hypothyroidism and\/or vitamin B<jats:sub>12<\/jats:sub> deficiency.
