菌状息肉症を合併した胸腺腫の1例

Thymoma Presenting Synchronously with a Mycosis Fungoides；Report of a Case

はじめに　菌状息肉症は皮膚原発のT細胞リンパ腫である．われわれは，菌状息肉症を合併した胸腺腫の1切除例を経験したので，若干の文献的考察とともに報告する．

A 65-year-old woman presented with mycosis fungoides and an anterior mediastinal tumor. Stage Ⅱa mycosis fungoides was treated with bath psoralen plus ultraviolet A, topical corticosteroids, and oral bexarotene. One month later, a surgical resection was performed for the anterior mediastinal tumor, which was a stage Ⅱ thymoma with membrane invasion. Furthermore, adjuvant radiotherapy was performed for anterior mediastinum. The mycosis fungoides lesion exacerbated after 3 months；thus, chemotherapies were performed. The patient died of respiratory insufficiency due to multiple pulmonary metastases of mycosis fungoides 1 year after the operation.
