To illustrate a newly recognized histopathologic change in a patient with canalicular obstruction after weekly administration of 5-fluorouracil for colon cancer.
Interventional case report.
A full-thickness section of canaliculus was obtained during surgical repair.
Histopathologic changes in the specimen.
The prominent histologic feature of the canalicular specimen was severe squamous metaplasia with narrowing of the lumen.
Canalicular obstruction may follow systemic use of 5-fluorouracil due to squamous metaplasia.
阐述一名结肠癌患者在每周接受5-氟尿嘧啶治疗后出现小胆管阻塞时新发现的组织病理学变化。
介入性病例报告。
在手术修复过程中获取小胆管全层切片。
标本的组织病理学变化。
小胆管标本的显著组织学特征为严重的鳞状化生伴管腔狭窄。
由于鳞状化生，全身使用5-氟尿嘧啶可能导致小胆管阻塞。
