Linear radiodermatitis following total body electron beam therapy.

Background, We describe herein a peculiar clinical presentation of a linear overlapping radiodermatitis, localized on the internal side of the limbs, following a total body electron beam therapy. Case report. A 68-year-old-man was treated in April 1998 by a total body el ectron beam therapy, for a stage I mycosis fungoides. Few days after the la st irradiation, the patient suffered from a linear eruption localized on th e internal side of the limbs and the external side of the abdominal wall. Discussion. Total body electron beam therapy can be proposed in early stage mycosis fungoides with localized or generalized cutaneous lesions. Because penetration depth of electron is well controlled and is limited to the ski n, usual side effects of total body electron beam therapy do not concern in ternal organs (bone marrow,...). We report here a peculiar clinical present ation of a linear radiodermatitis in frontal plane which has not been repor ted to date, to our knowledge. This radiodermatitis corresponds to overlapp ing of posterior and anterior fields of irradiation.
