経過中に白斑とＬｅｓｅｒ‐Ｔｒｅｌａｔ徴候が出現した皮膚悪性リンパ腫（ＣＴＣＬ）

Abstract

We reported a case of cutaneous T cell lymphoma (CTCL) associated with multiple seborrheic keratosis and vitiligo. A reddish nodule appeared on the chest of a 63 years old Japanese male patient, and the noduler lesions continued to appear on his trunk, head and neck. Examinations including skin biopsy established the diagnosis of CTCL of non-mycosis fungoides type. Two years later, multiple seborrheic keratosis suddenly appeared on his trunk accompanied by severe itching. In addition, vitiligo-like depigmentation developed surrounding a lymphoma lesion in his left axilla. We concluded this case was unique CTCL showing Laser-Trélat sign and associated with vitiligo-like depigmentation.
