An Isolated Vertebral Metastasis of Urachal Adenocarcinoma

Abstract

Abstract We describe a case of urachal adenocarcinoma arising in a 30-year-old woman. The patient underwent partial cystectomy. Three years later, she presented with an isolated metastasis to a thoracic vertebra, which was treated by vertebral corporectomy. Histologic findings are described, and the clinical findings, management, and metastatic patterns of this rare tumor, as well as the differential diagnosis on a biopsy specimen, are discussed.
