ABSTRACT
Panton-Valentine leukocidin-producing (PVL) Staphylococcus aureus is responsible for a highly lethal necrotizing pneumonia, which occurs predominantly in young immunocompetent patients. Hemoptysis and leucopenia often occur but are not always present. Detection of PVL gene on S. aureus strains responsible for pneumonia should help us to a better understanding of this disease, to improve its treatment with antibiotics capable of lower the toxin production and to prevent its diffusion to others persons by detection and elimination of a nasal S. aureus carriage.

A 50-year-old man developed a bronchogenic cyst complicated by hemorrhage. A complete radiographic chest work-up provided a reliable diagnostic approach. Bronchogenic cysts are usually asymptomatic incidental discoveries. Chest ultrasonography confirms the cystic nature of the mediastinal mass. Computed tomography scan and especially magnetic resonance imaging further support the diagnosis and are helpful for guiding surgery. Surgery is required because of the unpredictable risk of hemorrhage, infection or enlargement.

Plasmodium vivax malaria late-forms rarely exceed two years--the authors reported a late-form more than twenty years after a stay in endemic area. This late-form occurred in an immunocompromised patient with two terminal-stage neoplasia receiving radio, chimio corticotherapy associated with anemia and thrombopenia. Repeated-tests allowed the diagnostic.
