Granulomatous inflammation is a histologic finding with a relatively wide variety of causes. In general, considerations include infectious etiologies, autoimmune conditions, or foreign body reactions. Granulomatous inflammation is uncommonly seen in the placenta. We present a unique case of a young woman with preterm labor and rupture of membranes whose placenta demonstrated perivascular decidual granulomata in the membranes and the basal plate.
