Introduction.Mycoplasma pneumoniae is a small cell-wall-lacking bacterium that belongs to the mycoplasma (Mollicutes) prokaryote micro-organisms. It is a common cause of both upper and lower respiratory tract infections in all age groups. Respiratory illness is the most common manifestation of M. pneumoniae infection; however, extrapulmonary involvement may be present or predominant. The skin, mucus membranes, central nervous system, cardiovascular system, haematopoietic system, kidneys and musculoskeletal system are the most commonly involved extrapulmonary sites. Immune thrombocytopenia purpura has been reported as a rare haematological manifestation of mycoplasma infection. Here, we report, with a literature review, the case of a young adult with M. pneumoniae infection, presenting with acute febrile illness, myringitis, erythema multiforme, mild Raynaud's phenomenon symptoms and severe thrombocytopenia. Case presentation. Our patient was a 24-year-old healthy man who presented to an emergency department with acute febrile illness, upper respiratory tract infection symptoms, myringitis, erythema multiforme skin lesions, severe thrombocytopenia, and pale and cold hands. Mycoplasma serology suggested acute M. pneumoniae infection. The patient had a complete resolution of symptoms and gradual recovery from the thrombocytopenia after a course of anti-Mycoplasma therapy with azithromycin. Our case illustrates the multi-system involvement of M. pneumoniae infection. Conclusion.M. pneumoniae is a frequent cause of upper and lower respiratory tract infections in children and young adults. Multi-system involvement including the skin, vascular and haematological systems in young adults with upper or lower respiratory tract infection, as in our patient, should raise the suspicion of Mycoplasma infection. Our case also illustrates an excellent clinical response and recovery from thrombocytopenia shortly after anti-Mycoplasma antimicrobial therapy.
