Erythema multiforme caused by Mycoplasma pneumoniae infection in 3 children / 中华实用儿科临床杂志

ABSTRACT

Objective:To summarize the clinical features, diagnosis and treatment of erythema multiforme caused by Mycoplasma pneumoniae infection.Methods:The data of clinical features, treatment and prognosis of children diagnosed with erythema multiforme caused by Mycoplasma pneumoniae infection and treated in the First Affiliated Hospital of Zhengzhou University from Jane 2016 to December 2019 were retrospectively analyzed, and related literature was summarized.Results:All the 3 patients suffered from fever, cutaneous and mucous membrane lesions.Cutaneous lesions were manifested as exudative erythema multiforme, and the mucous membranes involved included oral mucosa, ocular conjunctiva and genital mucosa.The symptoms in all 3 cases were alleviated after the treatment with glucocor-ticoid, high doses of gamma globulin, anti-Mycoplasma pneumoniae and symptomatic support.Two children suffered secondary infection during treatment and improved with anti-infection.Neither patients had sequelae during the follow-up.Conclusions:Mycoplasma pneumoniae can cause erythema multiforme in children, but it is always misdiagnosed due to its clinical rarity.The mechanism of erythema multiforme caused by Mycoplasma pneumoniae infection is not clear.Early administration of glucocorticoid and high doses of gamma globulin, anti-Mycoplasma pneumoniae and symptomatic support often lead to a good prognosis.
