Malignant rectal strictures are uncommon, but they may pose a diagnostic challenge in clinical practice. We report the case of an 85-year-old male with an initially puzzling presentation of abdominal distention and discomfort. The patient was ultimately diagnosed with a rectal stricture caused by a plasmacytoid variant of urothelial cell carcinoma originating from the bladder. This case emphasizes the necessity of considering unique etiologies when evaluating rectal strictures and the aggressive character of this type of urothelial carcinoma.
恶性直肠狭窄并不常见,但在临床实践中可能带来诊断挑战。我们报告一例85岁男性病例,其最初表现为腹胀和不适,令人困惑。该患者最终被诊断为直肠狭窄,病因是起源于膀胱的浆细胞样变异型尿路上皮癌。本病例强调了在评估直肠狭窄时考虑独特病因的必要性以及这类尿路上皮癌的侵袭性。
