The article very well written and clinically important, but why did the author not mention the option of using polymerase chain reaction (PCR) as a diagnostic tool? PCR is not a universal diagnostic miracle weapon, but when it works it does so within just a few days and is highly specific. Another advantage is that it can be performed using minimal volumes of aspirates, etc. Even if the procedure was not used in the specific case presented in the article it should have been evaluated in the discussion. The same holds true for both the disease and the test: They need to be borne in mind.
