[Bladder adenocarcinoma of urachal origin. A rare tumor].
With the description of this new case of urachal adenocarcinoma in the vesical cupula we provide a review on the clinical, pathological and immunohistochemical aspects of this rare tumour, as well as a diagnostic and therapeutical approach. Its subepithelial infiltrant nature delays discovery and denotes both an insidious evolution and poor prognosis. Mucinoid production, nodes pattern and certain immunohistochemical substances as well as abnormalities in the cell's DNA content are attributes of this entity. Only surgery, either partial or exeresis, is effective since this is a radioresistant and dubiously chemosensitive tumour.
