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 electron beam therapy, for a stage I mycosis fungoides. Few days after the last irradiation, the patient suffered from a linear eruption localized on the 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 skin, usual side effects of total body electron beam therapy do not concern internal organs (bone marrow,.). We report here a peculiar clinical presentation of a linear radiodermatitis in frontal plane which has not been reported to date, to our knowledge. This radiodermatitis corresponds to overlapping of posterior and anterior fields of irradiation.
