The article describes a case study retrospective analysis of community-acquired pneumonia (CAP) with a morbilliform toxic allergic reaction in a 57-year-old female patient to demonstrate the differential diagnosis complexity of measles in comparison with CAP with a toxic allergic reaction. The article also shows the action sequence of specialists at an infectious in-patient hospital in case of suspected measles, considering the available epidemiological history. The peculiarity of this follow-up is the presence of epidemiological, anamnestic, clinical and laboratory-instrumental data indicating measles standard case. The exclusion of measles became possible only after receiving an IgM negative result to the measles by enzyme immunoassay. The unfavorable factors of the CAP severe course were the lack of proper follow-up of exposed patients in the measles outbreak, independent uncontrolled use of nonsteroidal anti-inflammatory drugs at the outpatient stage, late seeking medical help (7^th day of disease, 5^th day of rash), the presence of hormone-dependent asthma as a concomitant disease. The presented case study combines the presence of pneumonia accompanied by exanthema and allows to identify drawbacks both at the outpatient and in-patient stages of medical care.

Keywords: measles, community-acquired pneumonia, maculopapular rash, toxic allergic reaction, differential diagnosis.
