Gemcitabine-related "pseudocellulitis": report of 2 cases and review of the literature.

Gemcitabine is a chemotherapeutic agent whose cutaneous toxicities are easily mistaken for infections. We describe 2 patients, 1 with gemcitabine-induced radiation recall dermatitis and 1 with gemcitabine-related erysipeloid reaction, who received misdiagnoses of infectious cellulitis and were given empirical antibiotics. Recognition of these syndromes is important to avoid unnecessary antibiotic use.
