Fixed drug eruption with significant hyperpigmentation secondary to acetaminophen. A fixed drug eruption presents as a distinct lesion or lesions after systemic drug exposure. It is often underdiagnosed, which leads to recurrences when and if the drug is readministered. This eruption generally appears as sharply circumscribed, round to oval patches or plaques that may be single or multiple.
