Abstract:
Mycoplasma pneumoniae is a common respiratory pathogen that causes a wide range of clinical
manifestations, from mild upper respiratory tract infections to severe atypical pneumonia. Besides its
pulmonary involvement, it can cause several extrapulmonary complications. Among these, dermatological manifestations such as Stevens-Johnson syndrome, erythema multiforme, and toxic epidermal necrolysis are well recognised. Reactive infectious mucocutaneous eruption is a relatively rare but notable manifestation. This case report describes a 35-year-old man who developed mucosal lesions involving the ocular, oral, and genital areas after a prodrome of respiratory symptoms. Laboratory tests confirmed a high antibody titre of Mycoplasma pneumoniae. While initial antibiotic therapy improved the respiratory symptoms, mucosal involvement persisted, necessitating the use of systemic corticosteroids, which led to a significant clinical improvement. This case highlights the importance of timely recognition and correct management of this uncommon manifestation of mycoplasma infection.
