Abstract The Authors present a case illustrating factitious disorder, who was previously diagnosed as schizophrenia for 2 years, with a comorbidity of depressive disorder (unspecified) and obsessive-compulsive disorder. The factitious presentation involved exaggeration of symptoms, demanding and challenging behavior towards medical personnel, prolonging of sick role by refusing necessary intervention. Diagnosis of schizophrenia complicated patient’s condition when poly-pharmacy was introduced. The element of deception too provided difficulty in clinician to identify other comorbid psychiatric issue of depression and Obsessive Compulsive Disorder (OCD), with the suspicion of Borderline Personality Disorder. We emphasize the importance of recognizing possible signs of deception through looking at the atypical presentation throughout the treatment course and consequences following the misdiagnosis.
