Abstract
PURPOSE OF REVIEW
Symmetrical drug-related intertriginous and flexural exanthema (SDRIFE), previously termed drug-related baboon syndrome, is
a benign and self-limiting type IV hypersensitivity reaction characterized by symmetrical erythema involving the gluteal and
intertriginous areas in the absence of systemic involvement. It may also occur in the absence of previous drug exposure.
RECENT FINDINGS
Antibiotics, in particular beta-lactams, comprise the majority of causes of SDRIFE. Other drugs which have been implicated
include antihypertensives, radiocontrast media, chemotherapeutic agents, and biologics. Histology of lesional skin is variable
with predominance of superficial perivascular inflammatory cell infiltrates. Outcomes of allergy tests are variable with positive
delayed intradermal tests reported for penicillin V, allopurinol; positive patch tests for erythromycin, mitomycin, nystatin,
pseudoephdrine; positive lymphocyte transformation tests for erythromycin; and positive drug provocation tests for clindamycin,
cimetidine, corticosteroids, terbinafine, and valacyclovir.
SUMMARY
Diagnosis of SDRIFE is dependent upon recognition of the clinical morphology and distribution of the rash, and its temporal
relationship to the use of the suspected drug. Outcomes of in-vivo and in-vitro tests have been inconsistent, and thus may
not be useful in the identification of the putative drug.
