Mycoplasma pneumoniae-associated Mucositis: A Recently Described Entity

Abstract

Mycoplasma pneumoniae (MP) is a common cause of respiratory infections and can be associated with extrapulmonary complications. MP mucositis has recently been described as a distinct endemic clinical entity called Mycoplasma pneumoniae-induced rash and mucositis (MIRM). The authors present the case of a 46-year-old man with atypical pneumonia associated with exuberant mucositis, conjunctival hyperaemia and positive serological assays for MP IgM. The patient was treated with azithromycin and systemic corticosteroid therapy. Supportive care including pain management, intravenous hydration and mucosal care was also given. There was complete resolution of the pneumonia and mucositis. The presence of atypical pneumonia with mucosal involvement without cutaneous lesions and a favourable clinical evolution led to the diagnosis of MIRM.
