The article description and significance to dermatologists: bleomycin flagellate dermatitis is a rare cutaneous manifestation, believed to be due to the lack of bleomycin hydrolase enzyme in the skin, which inactivates bleomycin, resulting in its accumulation. This is thought to be a dose-dependent reaction, and doses over 200 U and higher may increase risk. This case describes a male developing a pruritic, erythematous linear flagellated dermatitis to the lower back after his third cycle of bleomycin, etoposide and cisplatin for a stage 3 seminoma. Pruritis resolved and erythema improved with the treatment of bilastine and desoximetasone cream. It is important to recognize this condition because untreated pruritis may lead to increased impairment of the skin barrier in already immunocompromised patient populations. This may also give further evidence to having ongoing and continuing collaboration between Dermatology and Medical Oncology for any patients presenting with a new rash undergoing chemotherapy treatments.
