Un syndrome fébrile rare.

This case report concerns a 57-year-old man who developed an exanthem-like rash, digestive symptoms and an inflammatory syndrome after taking allopurinol. The patient was admitted to the general medical ward, where a number of hypotheses, including infectious, digestive and cardiac, were considered and then ruled out. After empirical antibiotic treatment, the medical team raised the possibility of DRESS syndrome, a serious and potentially fatal hypersensitivity reaction to drugs, leading to the patient’s transfer to a specialist department. This clinical case highlighted the frequency and diversity of manifestations of DRESS syndrome, which can present cutaneous and digestive symptoms and affect several organs such as the liver, kidneys, lungs, heart and pancreas. Despite the delay in diagnosis, the patient did not develop any serious complications associated with DRESS syndrome. This case study highlights the importance of prompt and appropriate management to improve the prognosis of patients suffering from this potentially fatal condition. [ABSTRACT FROM AUTHOR]
