Abstract:
The physician's approach to the differential diagnosis of obscure, atypical pneumonias has changed. The physician needs to expand the diagnostic search when confronted with a perplexing, progressive atypical pneumonia. Diseases examined in this article include anthrax, psittacosis, Q fever, tularemia, pasteurellosis, melioidosis, Rocky Mountain spotted fever, and the plague.
Insights
Physicians must broaden their diagnostic search for progressive atypical pneumonias. This article reviews rare causes like anthrax, psittacosis, Q fever, tularemia, and plague.
