Self-provoked oral illness: When the mouth mirrors the soul

Factitious disorder imposed on self (FDIS), also known as Munchausen's syndrome, is a psychological disorder characterized by falsification of physical or psychological symptoms without an obvious external incentive. Oral presentations of FDIS are infrequently reported, and diagnosis might be challenging because affected patients often have impressive skills in fabricating symptoms and deceiving healthcare professionals.

To describe the diagnostic dilemma and management challenges in a female patient who presented with tooth ache and oral ulcers.

A 53-year-old female presented with complex medical history, vague symptoms and confusing dental history regarding persistent toothache and generalized oral ulcers. She underwent extensive investigations and multiple dental and oral surgical procedures without reaching a confirmed diagnosis or achieving symptomatic improvement. Thorough review of her medical records revealed multiple admissions to various hospitals across the country and abroad for various reasons, and failed to find any laboratory, clinical, or radiographic evidence of her "claimed" symptoms.

Oral healthcare professionals should suspect FDIS in patients presenting with vague and complex history that is not explained by clinical or radiographic findings. Consultation with psychiatric department and hospital administration might be needed to confirm diagnosis and plan appropriate management of the case.
