Abstract
PDF Urachal mucinous tumor of uncertain malignant potential is very rare and is characterized by a multilocular cyst showing the proliferation of atypical mucin-secreting cells without stromal invasion. As in ovarian and appendiceal borderline tumors, it represents a transitional stage of mucinous carcinogenesis in the urachus. In addition, this tumor may recur locally and develop into pseudomyxoma peritonei. Due to its scarcity and diagnostic challenges, we report a mucinous tumor of uncertain malignant potential arising in the urachus.

Abstract
PDF
- Xanthogranulomatous inflammation of the urachus is a very rare benign chronic inflammatory disease of an unknown etiology. Herein we report a case of a 31-year-old woman who complained of lower abdominal pain and dysuria. Cystoscopy revealed a bullous change at the dome of the urinary bladder. MRI revealed a cystic mass above the bladder dome that extended to the umbilicus. A partial cystectomy with urachal resection was performed. Pathological examination revealed xanthogranulomatous urachitis combined with bullous cystitis.

Abstract
PDF
- Urachal adenocarcinoma is a rare tumor, and it has similarities with nonurachal adenocarcinoma; therefore, it is sometimes difficult to make a diagnosis. We present a typical case of urachal adenocarcinoma that had all the diagnostic criteria including the presence of an urachal remnant. A 65-year-old woman presented with complaints of a painless gross hematuria. Pelvic CT and cystoscopy showed an intraluminal protruding mass centered in the bladder wall. When diagnosed as adenocarcinoma with a signet ring cell component being noted by frozen biopsy, partial cystectomy with resection of the median umbilical ligament and peritoneum was carried out for a suspected urachal adenocarcinoma. The tumor morphology showed as typical mucinous adenocarcinoma. Characteristic tubular structures showing the typical histology of an urachal remnant was found in the perivesical fat. On immunohistochemical staining, the urachal adenocarcinoma showed a pattern similar to colonic adenocarcinoma, while the urachal remnant showed strong positivity for CK7 and Chromogranin A.
