Genital pyoderma gangrenosum revealing Behçet’s disease: a case report
Abstract Background Pyoderma gangrenosum (PG) is a rare and chronic neutrophilic dermatosis. It is clinically characterized by aseptic ulcerations preferentially located in the lower limbs. Its location in the genital area is unusual and could be a source of diagnostic difficulties. In half of the cases, PG is associated with an underlying disease. The association with Behçet’s disease is exceptional. Case presentation We report an original observation of a patient who presented a vulvar PG which revealed a Behçet’s disease. Conclusion The distinction between these two pathologies was difficult because of the similarity of the cutaneous-mucous lesions on the one hand, and the absence of histological specificity of these two pathologies on the other hand.
