In this report, we present a 51 year old postmenopausal woman with clinical presentation of “delusional disorder-somatic type” and also facial hirsutism and subclinical hypothyroidism. Blood tests revealed thyroid gland dysfunction with high TSH and anti-TPO levels but other blood tests and radiological investments were found to be normal. The relationship between thyroid dysfunction, hirsutism and psychosis is discussed in the context of this particular case. In presence of limited case reports in literature indicating a relationship with subclinical hypothyroidism and psychotic symptoms, we think that our case is important for reminding clinicians to consider endocrine disorders providing a basis for psychiatric disorders and to investigate thyroid function deficiency not only in patients with depression but with other psychiatric presentations like psychosis.
