Nafcillin implicated in a case of cutaneous and gastrointestinal leukocytoclastic vasculitis.

Leukocytoclastic vasculitis (LV) is a rare hypersensitive reaction involving the small vessels, which is usually mediated by drugs. Very few cases of nafcillin -associated LV have been reported. Here, we reported a case of LV with the presentation of skin rashes and gastrointestinal bleeding after receiving nafcillin, evidenced by endoscopy and skin biopsy.
