Background: Daylight photodynamic therapy (PDT) has been reported as having similar efficacy to conventional photodynamic therapy in actinic keratosis treatment.

Neutrophilic eccrine hidradenitis in a patient with FOLFOX chemotherapy.

This case study describes a 37-year-old Caucasian male with pruritic papules and plaques-some with central erosion-on the arms, neck, and trunk that appeared after chemotherapy with FOLFOX (folinic acid, fluorouacil, and oxiliplatin) for colon cancer. A histological examination showed features of neutrophilic eccrine hidradenitis. To the best of our knowledge, this is the first reported case of neutrophilic eccrine hidradenitis due to FOLFOX.
