LICHENOID DRUG ERUPTION ASSOCIATED WITH ANTITUBERCULAR DRUGS: A CASE REPORT

Tóm tắt

ABSTRACT

Lichenoid drug eruption, also known as drug-induced lichen planus, is an uncommon cutaneous adverse reaction caused by certain medications. It is characterized by the symmetric appearance of flat-topped, erythematous to violaceous papules resembling idiopathic lichen planus, typically involving the trunk and extremities. The latency period between initiation of the suspected medication and the onset of skin lesions may range from several weeks to over one year, largely depending on the nature of culprit drug, dosage and the patient’s individual response. Differentiating lichenoid drug eruption from idiopathic lichen planus can be challenging due to similarities in both clinical and histopathological features. In this study, we present a case of lichenoid drug eruption induced by anti-tuberculosis therapy, one among common triggers presented in clinical practice.
