    Desmoplastic small round cell tumor (DSRCT) is a rare, aggressive and malignant tumor that is characterized by nests of small tumor cells surrounded by a cellular and vascular collagenous stroma and predominantly affects young adolescent males. This tumor most commonly originates in the abdomen; however, in rare cases, DSRCT can originate in other body regions. The main manifestations of DSRCT are chest pain and respiratory symptoms, and patients' average survival after diagnosis is less than two years. In this report, we describe a case involving DSRCT of the lung that proved to be difficult to diagnose, and we conduct a literature review

    Community-Acquired Pneumonia and Empyema Caused by Citrobacter koseri in an Immunocompetent Patient

    Citrobacter species, belonging to the family Enterobacteriaceae, are environmental organisms commonly found in soil, water, and the intestinal tracts of animals and humans. Citrobacter koseri is known to be an uncommon but serious cause of both sporadic and epidemic septicemia and meningitis in neonates and young infants. Most cases reported have occurred in immunocompromised hosts. The infections caused by Citrobacter are difficult to treat with usual broad spectrum antibiotics owing to rapid generation of mutants and have been associated with high death rates in the past. We believe this is the first case described in the literature of a community-acquired pneumonia and empyema caused by Citrobacter koseri in an immunocompetent adult patient

    Moraxella (formerly Branhamella) catarrhalis was discovered at the end of the nineteenth century, and for many decades it was considered to be a harmless commensal of the upper respiratory tract. It is a Gram-negative, aerobic diplococcus considered to be the third most common pathogen isolated in childhood sinusitis and otitis media and in adult chronic lower respiratory disease, as well as an etiological agent of pneumonia in immunosuppressed patients or those with chronic obstructive pulmonary disease. Moraxella catarrhalis pneumonia is rarely associated with bacteremia. Here, we present two cases of community-acquired Moraxella catarrhalis bacteremic pneumonia
