[Acute generalized exanthematous pustulosis associated with Mycoplasma pneumoniae infection: a case report]
Abstract:
Acute generalized exanthematous pustulosis is an uncommon skin eruption, characterized by fever and the rapid onset of disseminated, non-follicular, sterile pustules, over an erythematous skin background. It is usually classified as a severe cutaneous adverse drug reaction, whose most relevant triggers are antibiotics and anticonvulsants. However, viral and bacterial infections have also rarely been associated with this dermatosis. We report the case of a patient, who developed lesions of acute generalized exanthematous pustulosis as an extrapulmonary manifestation of Mycoplasma pneumoniae infection.
Insights
Acute generalized exanthematous pustulosis (AGEP) is a rare skin reaction. This case highlights Mycoplasma pneumoniae infection as a rare, non-drug trigger for AGEP, presenting as an extrapulmonary manifestation.
Area of Science:
- Dermatology
- Infectious Diseases
- Clinical Medicine
Background:
- Acute generalized exanthematous pustulosis (AGEP) is an uncommon, severe cutaneous adverse drug reaction.
- AGEP typically presents with fever and widespread sterile pustules on an erythematous background.
- Common triggers include antibiotics and anticonvulsants, though infections are rarely implicated.
Observation:
- A patient presented with clinical features consistent with AGEP.
- The patient's condition was investigated for potential underlying causes.
- Mycoplasma pneumoniae infection was identified as the causative agent.
Findings:
- The patient developed acute generalized exanthematous pustulosis (AGEP).
- AGEP manifested as an extrapulmonary sign of Mycoplasma pneumoniae infection.
- This case expands the known spectrum of AGEP triggers.
Implications:
- Mycoplasma pneumoniae infection should be considered in the differential diagnosis of AGEP, particularly in atypical presentations.
- Recognizing infectious triggers is crucial for appropriate patient management and avoiding unnecessary drug cessation.
- This finding contributes to understanding the diverse etiology of severe cutaneous adverse drug reactions.
