title: Prayer nodules fine needle aspiration cytologic findings.
abstract: The enlarged prayer nodules from five patients were aspirated for cytologic studies. The fine needle aspiration yielded a cheesy material that showed keratin plaques and hair fragments. The cytologic interpretation of the nodules as multiple epidermoid cysts was confirmed by subsequent histologic study.
