Rare Skin Eruption Caused by Paracetamol: A Case of Acute Generalized Exanthematous Pustulosis

Background: This case report aims to enhance clinicians' ability to identify and effectively manage rare skin eruptions, specifically focusing on Acute Generalized Exanthematous Pustulosis (AGEP) by providing valuable insights into the context of its diagnostic challenges and clinical implications. Presentation of Case: We present a case of AGEP in a 16-year-old Indian boy who developed generalized pustulosis after taking Paracetamol (Acetaminophen). The patient's diagnosis was initially delayed due to the resemblance of AGEP with other skin conditions. Furthermore, the inadvertent reintroduction of Paracetamol exacerbated the condition. Discussion: We discuss various treatment options and emphasize the importance of prompt and accurate diagnosis of AGEP by utilizing the AGEP validation. By employing this scoring system, clinicians can enhance their diagnostic accuracy and avoid unnecessary delays in treatment initiation. Conclusion: The prompt identification of AGEP using the AGEP validation score is crucial for timely management. This case report highlights the potential risks associated with common drugs like Paracetamol and emphasizes the need for vigilance in prescribing medications. Clinicians should be aware of the distinctive features of AGEP and consider it as a differential diagnosis in patients presenting with pustular skin eruptions following drug intake. Improved awareness and application of diagnostic tools can aid in better patient outcomes.
