Symmetrical drug-related intertriginous and flexural exanthema (SDRIFE), and fixed drug eruption (FDE) are adverse cutaneous drug reactions. SDRIFE is most commonly associated with the use of beta-lactam antibiotics. There is only one case report describing SDRIFE due to intake of doxycycline in literature. Previously reported case describes the characteristic morphology of well-defined macular erythema over the flexural and intertriginous area. We here in report a 38-year-old male presented with unusual morphology of SDRIFE, and well circumscribed erythematous patches suggestive of FDE on the thigh and back after doxycycline intake. Histopathology was consistent with SDRIFE and FDE respectively. The skin lesions improved with 5 days of 40 mg oral prednisolone. After 6 weeks, drug provocation with doxycycline was done following which patient developed itching and erythema over the older sites. Though there is a single published report of SDRIFE due to doxycycline, our case had additional findings of having pigmented FDE lesions along with flexural lesions of SDRIFE.
