Radiation port wart: a distinct cutaneous lesion after radiotherapy.

Unlabelled: LABELED BACKGROUND: Radiotherapy may cause common cutaneous side effects such as acute and chronic radiodermatitis and also rare skin conditions.

Case Report: A 42-year-old woman who received radiotherapy for invasive breast carcinoma developed multiple, scaly, rough papules and nodules restricted to treatment fields six months after completion of the treatment. A relapse of the breast cancer and/or seborrheic keratosis was ruled out by histological confirmation of verruca vulgaris.
