Urachal Villous Adenoma Coexistent With Urachal Carcinoma: A Case Report

Year: 2025

Type: article

Abstract: Introduction: Urinary tract villous adenomas are uncommon, urachal villous adenomas being especially rare. While their malignant potential remains uncertain, villous adenomas may have malignant components. Here, we present a case of the coexistence of a urachal villous adenoma and urachal carcinoma. Case Presentation: We report the case of an 86-year-old woman with a urachal tumor of the bladder wall. A biopsy yielded a diagnosis of villous adenoma. Because of the possibility of coexisting malignancy, we performed a partial cystectomy, including excision of the umbilical ligament. Examination of the operative specimen revealed mucinous adenocarcinoma. She has remained recurrence-free for 8 months postoperatively. Conclusion: We here report the coexistence of a villous adenoma and mucinous adenocarcinoma of the urachus. Because urachal villous adenomas can have malignant components, they require aggressive treatment. This rare combination should be kept in mind.
