UNILATERAL AND SOLITARY RENAL METASTASIS FROM WELL DIFFERENTIATED THYROID CARCINOMA INITIALLY TREATED 22 YEARS BEFORE : A CASE REPORT

Abstract

他臓器の悪性腫療が腎臓に転移する例は，剖検では比較的多いが，生存中に転移が発見され臨床的に問題となることは稀れである。ことに甲状腺癌の腎転移は，1968年高安らによる報告1例のみである。最近われわれは52歳の女子で22年前に治療を受けた甲状腺乳頭状癌が左腎に弧立性に転移を来し，左腎摘除術を施行した症例を経験したので報告する。尚，本症は左腎摘除術後約1.5年目に腫瘍死したが， 24年間の全経過中, 局所リンパ節，骨，左腎，肝，筋，脳への転移が認められた。

A unilateral and solitary metastatic renal tumor from the papillary adenocarcinoma of the thyroid which was initially diagnosed 22 years ago was detected in a 52-year-old Japanese woman. In this case, the primary thyroid cancer had metastasized to the regional lymph nodes and to the bone. On the extremely slow course of the disease, the tumor remained active and developed metastases to the left kidney, to the liver and to the muscle. To our knowledge, this is the second case which was clinically evaluated. Tile literature was briefly reviewed.
