Radiation port dermatophytosis: tinea corporis occurring at the site of irradiated skin.
Radiation port dermatophytosis is the occurrence of tinea corporis within the area of radiation therapy delivery. A 68-year-old man, while receiving proton beam radiation for adenocarcinoma of the prostate, developed a dermatophyte infection in the area of the radiotherapy port. Including this patient, 4 patients with radiation port dermatophytosis have been reported in the world literature. The epidemiology, clinical manifestations, histopathology, diagnosis, pathogenesis, and treatment of this condition are discussed. The diagnosis of radiation port dermatophytosis may be missed because it is misinterpreted as radiation-induced dermatitis. Thus, it is possible that radiation port dermatophytosis may be more prevalent in patients receiving radiation therapy.
