“…The urachus is a tubular structure connecting the allantoid and the dome of the urinary bladder during fetal development, which is usually obliterated after birth and converted into the medial umbilical ligament. Occasionally in the event of incomplete atresia, urachal remnants consisting of tubular structures lined with transitional epithelium can be complicated with infection, cystic formation, or neoplasm development [ 1 ].…”

Cystic mucinous neoplasms of urachal origin cover a wide spectrum of benign and malignant lesions arising from the remnants of the urachus. They display various degrees of tumor cell atypia and local invasion, with no reported cases of metastasis or recurrence after complete surgical resection. We present a 47-year-old man who referred to our Surgical Department due to an abdominal cystic mass incidentally found upon abdominal ultrasound. He underwent en block resection of the cystic mass along with partial bladder dome cystectomy. The histopathology of the resected specimen revealed a cystic mucinous epithelial tumor of low malignant potential with areas of intraepithelial carcinoma. The patient showed no evidence of disease recurrence or distant metastasis 6 months after resection and is scheduled for follow-up with serial MRI or CT scans and blood tumor markers over the next 5 years.
