title: Eccrine poromas in a patient with mycosis fungoides treated with electron beam therapy.
abstract: We describe a 72-year-old man with mycosis fungoides (MF) followed up at our hospital for more than 20 years, who has developed 14 eccrine poromas (EPs) in the past 12 years. Twelve of these tumours were ascertained as EP histopathologically without any findings of malignancy and the other two were clinically diagnosed and are not yet resected. To our knowledge, this is the first case report of MF complicated with multiple EPs. In our patient, all EPs arose in skin areas previously irradiated with an electron beam for the treatment of MF, suggesting that electron beam irradiation might have an effect on the development of EPs.
