Case report: Schizophrenia and hypertrophic osteoarthropathy, a rare syndrome hiding a life-threatening condition

Schizophrenia is associated to somatic disorders especially cardio-vascular and auto-immune. Through this case report, we describe an association with hypertrophic osteoarthropathy (HPO). For this patient, it was a paraneoplastic syndrome secondary to lung cancer. This syndrome is rare but important to recognize since it could hide a life-threatening condition.
