INTROODUCTION
Hypertrophic osteoarthropathy (HPO) is a rare syndrome that can be idiopathic or secondary to an infection, an inflammation or a malingering cause mainly affecting intrathoracic organs.
Clinically its more prominent symptom is finger clubbing, other symptoms can be seen such as tenderness in the palpation of tubular bones or periosteal proliferation (1).
As a psychiatrist, it would be important to recognize this clinical entity, because on one hand patients with schizophrenia can have difficulties expressing their physical grievances (2) and on the other hand as rare as this condition is it can hide a serious underlying disease. This would be illustrated in this case report.
