Addison's disease caused by adrenal tuberculosis may lead to misdiagnosis of major depressive disorder: A case report.

Background: Addison's disease (AD) is a rare but potentially fatal disease in Western countries, which can easily be misdiagnosed at an early stage. Severe adrenal tuberculosis (TB) may lead to depression in patients.

Case Summary: We report a case of primary adrenal insufficiency secondary to adrenal TB with TB in the lungs and skin in a 48-year-old woman. The patient was misdiagnosed with depression because of her depressed mood. She had hyperpigmentation of the skin, nails, mouth, and lips. The final diagnosis was adrenal TB that resulted in the insufficient secretion of adrenocortical hormone. Adrenocortical hormone test, skin biopsy, T cell spot test of TB, and adrenal computed tomography scan were used to confirm the diagnosis. The patient's condition improved after hormone replacement therapy and TB treatment.

Conclusion: Given the current status of TB in high-burden countries, outpatient doctors should be aware of and pay attention to TB and understand the early symptoms of AD.
