A rare case of symmetrical drug-related intertriginous and flexural erythema with tamoxifen use.

Symmetrical drug-related intertriginous and flexural erythema is characterized by a diffuse symmetric rash of the gluteal and intertriginous areas with only one published report of association with tamoxifen. It is imperative for clinicians to recognize tamoxifen-induced SDRIFE to avoid life-threatening dermatologic complications, which can be resolved with discontinuation of tamoxifen.
