Although Mp-induced pneumonia is usually a self-limiting disease, refractory life-threatening pneumonia is often induced. In addition, the development of alternative therapeutic strategies for Mp is expected because of the emergence of antibiotic-resistant Mp.
Kikuchi–Fujimoto disease (KFD) is a self-limited disease that is more common in young Asian women. Typical presentations included fever and cervical lymphadenopathy. The etiology of KFD is unknown, and diagnosis is based mainly on lymph node biopsy. KFD has been reported to be associated with Mycoplasma pneumoniae infection. However, the role of antibiotic treatment is unclear. We reported 2 cases of KFD associated with Mycoplasma pneumoniae infection and were successfully treated with a macrolide.
Mycoplasma pneumoniae is commonly associated not only with atypical pneumonia, but also with different clinical features. The paper reports the case of a 10-year-old girl with pneumonia, fictitious anaemia, due to the presence of cryo-agglutinins, and autoantibodies induced by Mycoplasma pneumoniae infection.
