title: Actinomycosis after allogeneic hematopoietic stem cell transplantation despite penicillin prophylaxis.
abstract: Actinomycosis is a rare chronic and multifaceted disease caused by Actinomyces species frequently mimicking malignancy or other chronic granulomatous lung diseases. We report 4 original presentations of actinomycosis arising under supposed penicillin prophylaxis in allogeneic stem cell transplantation recipients.
