Introduction:
Adverse cutaneous drug reactions involve a variety of clinical
manifestations, ranging from minor skin rashes to fatal hypersensitivity
reactions. Drug reaction with eosinophilia and systemic symptoms
(DRESS), also known as drug-induced hypersensitivity syndrome (DIHS), is
one of these manifestations. This pathology, which can lead to death in
10% of cases [1][2], is commonly overlooked and misdiagnosed
[3].
Through this paper, a case of Allopurinol-induced DRESS syndrome with
initial oral mucosal involvement is presented while emphasizing the
importance of early diagnosis to achieve the appropriate management.
