頭部の熱傷瘢痕局面に悪性黒色腫と有棘細胞癌の同時発生をみた1例

抄録

We reported a rare case of malignant melanoma and multiple squamous cell carcinoma, occurring simultaneously on a burn scar. A 49-year-old woman had been burned on her scalp in childhood, resulting in a scar. At the age of 48, she was diagnosed breast cancer, and received a breast resection. After two or three months, she found an enlarged multiple tumor on the burn scar. Histologically, one was nodular melanoma, the other was squamous cell carcinoma. The cause is likely to be a reduction of tumor immunity. [Skin Cancer (Japan) 2002; 17: 79-82]
