Unusual presentations of infection in neutropenic patients

Neutropenic patients may have unusual presentations of infection because of their inability to mount an adequate inflammatory response and their susce ptibility to infection caused by less virulent organisms. About 60% of febr ile episodes are associated with no other signs and symptoms and no infecti ng organism can be identified, yet most respond to antibacterial therapy. I f not treated promptly, infection in neutropenic patients can progress rapi dly. Unusual sites of infection include typhlitis, perirectal infections an d atypical forms of cellulitis.
