Retroperitoneal necrotizing fasciitis secondary to Fournier’s gangrene

Background The retroperitoneal necrotizing fasciitis is an extremely rare, usually lethal clinical entity and there are very few reported cases. If necrotizing fasciitis affects the retroperitoneum, a nonspecific signs and symptoms associate a higher mortality. For this reason, the diagnostic suspicion and the early surgical debridement are basic for a satisfactory result.
