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.
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.
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.
我们在此描述了一例全身电子束治疗后发生在四肢内侧的线性重叠放射性皮炎的特殊临床表现。
一名68岁男性于1998年4月接受全身电子束治疗，用于治疗Ⅰ期蕈样肉芽肿。最后一次照射后几天，患者四肢内侧和腹壁外侧出现线性皮疹。
全身电子束治疗可用于早期蕈样肉芽肿伴有局限性或全身性皮肤病变的情况。由于电子的穿透深度易于控制且仅限于皮肤，全身电子束治疗的常见副作用不涉及内部器官（骨髓等）。据我们所知，我们在此报告了一种至今尚未报道过的额面线性放射性皮炎的特殊临床表现。这种放射性皮炎对应于前后照射野的重叠。
