Facial dismasking法を用いて摘出し得た側頭窩の転移性腎細胞癌の1例

A case of metastatic renal cell carcinoma to the temporal fossa：resection of tumor with facial dismasking approach

Ⅰ　はじめに

　腎細胞癌は原発治療後，長期間経過した後でも再発転移することが知られている。今回，原発治療10年以上経過した後に発症した右側頭窩を占拠する転移性腎細胞癌に対し，術野の展開にFacial dismasking法を用いることで顔面に目立った瘢痕，顔面神経麻痺などの機能障害をきたすことなく摘出が可能であった症例を経験したので文献的考察を加えて報告する。

　We reported the first case of metastatic renal cell carcinoma to the temporal fossa 14 years after tumor nephrectomy. A 59-year-old male had been aware of a swelling mass at the right temporal region for 3 years. Under a diagnosis of metastatic renal cell carcinoma,surgery was performed with facial dismasking approach. There was no apparent cosmetic complications including facial palsy. The patient was currently free from disease one year after surgery. The facial dismasking approach leads to excellent access for resection of a tumor involving the temporal fossa with minimum damage to facial skin and well-preserved facial movement.
