Initial Clinical Evaluation

Primary malignancy of the urachal remnant is a rare neoplasm that accounts for less than 0.01% of all adult cancers, with an estimated annual incidence of 1:5 million. The tumour carries a grave prognosis that attests to its highly aggressive nature. Owing to its extra-peritoneal location, the tumour runs a relatively silent clinical course until late presentation, when most patients display extensive local invasion and metastatic spread. In this report, we highlight a case of primary malignancy of the urachus that on initial clinical evaluation masqueraded as a Sister Mary Joseph’s nodule. Characteristic imaging features, however, proved decisive in establishing the diagnosis of a urachal carcinoma.

A 57-year-old man presented with a 6-month history of pelvic fullness. He had no lower urinary tract symptoms or altered bowel habits. On examination, there was a non-tender pelvic mass which extended from the pubic symphysis to the level of the umbilicus. CT scan of the abdomen demonstrated a 22×11×11 cm cystic mass arising from the pelvis extending into the midline and superiorly to the umbilicus. Other than raised carcinoembryonic antigen of 7.6 ng/mL (<5.0), the remainder of his blood test were unremarkable. Flexible cystoscopy demonstrated a convex deformity of the bladder wall in keeping with the compression and displacement as seen on the CT. The patient underwent an open excision of the cystic structure (urachal remnant), partial cystectomy, partial excision of anterior abdominal wall and pelvic lymphadenectomy. A check cystogram performed 12 days following the initial operation was unremarkable.

Only 28 cases of pseudomyxoma peritonei (PMP) arising from urachal neoplasms have been reported. We report one example of this extremely rare disease with KRAS mutational status in its spectrum of pathology. A 45-year-old woman presented with urachal frankly invasive mucinous cystadenocarcinoma confined to the dome of the bladder, which clinically manifested as PMP and was not detected at the first surgery. The primary tumour was revealed 6 months later because of its recurrence as PMP. Microscopic investigation revealed tubular adenoma and cystadenocarcinoma communicating with the bladder lumen and transitioning from the urachal urothelium to the mucinous epithelium. A urachal remnant was identified near the neoplasm. On immunohistochemistry, the tumour proved positive for CK7, CK20, CEA, and CDX2. Staining for β-catenin revealed expression in both the cytoplasm and cell membrane. Mismatch repair protein expression was normal. Somatic KRAS-mutation (G12V) was revealed in tubular adenoma, cystadenocarcinoma, and mucinous carcinoma peritonei and may play an oncogenic role in the malignant transformation of urachal mucosa and the development of PMP.
