Toxic erythema of chemotherapy secondary to gemcitabine and paclitaxel

Toxic erythema of chemotherapy (TEC) is an infrequently reported cutaneous condition, with diagnosis predominately based on clinical presentation, histologic findings, and known reported associations. Therefore, it is important to both recognize common presentations of TEC and be mindful of chemotherapeutic agents associated with this cutaneous side effect to prevent misdiagnosis and prolonged time to treatment. Herein, we present a patient with TEC occurring in intertriginous skin (malignant intertrigo) with classic clinical and histologic findings. In our patient this was associated with a combination neoadjuvant gemcitabine and paclitaxel therapy, a relationship that, to our knowledge, has yet to be reported in the literature.
