熱傷瘢痕上に生じた線維肉腫—14年前に熱傷瘢痕癌をみた1例

FIBROSARCOMA DEVELOPED IN AN OLD BURN SCAR:A ASE WHICH DEVELOPED SPINALIOMA IN THE SAME BURN SCAR 14 YEARS PREVIOUSLY

　熱傷瘢痕上に受傷後数十年を経て，悪性腫瘍の発生をみることは稀ではないが，その大部分は有棘細胞癌であり，時に基底細胞癌を生ずることもあるが，肉腫の発生をみることは，きわめて少ない．

　軟部組織にみられる線維肉腫の発生誘因としては，外傷，放射線照射等があげられているが，熱傷瘢痕もその一誘因になり得ると考えられる．文献を渉猟したところ，本邦においては，村上^17）の症例以来7例の熱傷瘢痕肉腫の報告がみられ，欧米においても，Fleming^14），Pack^3），Gaynor^9）等に同様の報告例をみる．

A 47-year-old man had had spinalioma in an old burn scar, 15 years previously. He had founcl a tumor in the same burn scar of his thigh few months ago. It grew rapidly and became a tennisball sized tumor. Histologic specimen proved to be the fibrosarcoma. The lesion was excised wide localy, and split-thickness skin grafting was performed.

The case of fibrosarcoma developing in a burn scar is very rare, only 8 cases were reported in Japan.

This reported case is very interesting because of spinalioma and fibrosarcoma developed in the same burn scar.
