ABSTRACT
The periarteritis nodosa [PAN] is a serious necrotizing vasculitis. Healing is, classically, obtained after a long-term treatment using corticosteroids and immunosuppressive agents. Purpose: Reporting the case of a NAP or was spontaneous healing without having recourse to any immunosuppressive treatment. We report an observation of a patient aged 27 monitoring for manic-depressive psychosis hospitalized for a fever during the course associated with high blood pressure [hypertension], a weight loss, asthenia and myalgia. Biology was a biological inflammatory syndrome [SIB], a creatinine 1 15p mol/1. The survey infectious and immunological balance were negative. The arteriography showed a strongly evocative of the NAP. We have seen no sign of poor prognosis. The recovery was spontaneous after a short period of evolution with an amendment clinical and biological weapons. The patient was put under anti-HTA and reviewed regularly to the consultation. An analogy is drawn between such developments and already reported in some cases of viral PAN. The actual frequency of self-limiting PAN is unknown. The scarcity of cases reported in the literature may in part be attributed to ignorance
