Carcinoid Tumor of the Urinary Bladder: Case Report and Literature Review

膀胱類癌瘤:病例報告併文獻回顧

摘要


類癌瘤源自於腸嗜鉻細胞,可以在各種源自於胚胎神經脊的組織中被發現。雖然腸胃道及呼吸道器官是最常見的來源,但已有少數源自於泌尿生殖道,包含腎臟及膀胱的病例被發表。在此,我們報告一位五十五歲女性意外由電腦斷層發現膀胱腫瘤,並順利經尿道以內視鏡手術切除腫瘤,病理報告證實是具有chromogranin A陽性免疫螢光染色的類癌瘤。目前於一年之追蹤期內,尚未發現有腫瘤復發之情形。

並列摘要


Carcinoid tumors arise from enterochromaffin cells and can be found in any tissue derived from the embryonic neural crest. Although an origin from the gastrointestinal and respiratory organs is most common, rare carcinoid tumors encountered in the genitourinary tract, including the kidney and urinary bladder have been reported in the English literature. Herein, we present a 55-year-old woman with an incidental finding of a bladder tumor on computed tomography. She underwent a smooth transurethral resection of the bladder tumor, and the pathology confirmed a carcinoid tumor positively stained for chromogranin A, an immunohistochemical marker. During 1 year of follow-up, no recurrence of the disease was noted.
