A 61-year-old woman was admitted to our hospital because of abdominal pain. Computed tomography showed an abscess in the anterior abdominal wall and an intraabdominal tumor. Biopsy from bladder dome presented adenocarcinoma. We diagnosed the tumor as urachal carcinoma and operation was performed. The resected specimen showed transverse fistula. In Japan, there is no report of urachal carcinoma with fistula to digestive duct. We think it is a cause of strong infiltration of the carcinoma. Curative resection for urachal carcinoma with fistula can lead to a better prognosis, in spite of its invasive character.

Article Synopsis
- The urachus is a leftover structure from fetal development that connects the bladder to the belly button, and cancers arising from it, known as primary urachal carcinoma, are rare but aggressive.
- A case study presents a 48-year-old woman with abdominal pain and a mass, which was diagnosed as squamous cell carcinoma after imaging and biopsy.
- Treatment typically involves surgery to remove the tumor and surrounding tissue to reduce the chance of spreading, but guidelines are sparse due to the rarity of this type of cancer, with current protocols based on limited data.

Introduction And Importance: Urachal carcinoma (UrC) is a rare bladder malignancy originating from the urachus. Comprising around 90 % adenocarcinomas, most cases are invasive. Urachal adenocarcinoma is less common than its non-urachal counterpart and is recognized for its aggressive nature, often diagnosed at advanced stages with a poor prognosis.

Article Synopsis
- * Most urachal cancers are classified as intestinal adenocarcinomas (90%), and they often occur in the lower urachal tube or bladder dome, leading to late diagnoses due to the silent nature of early stages.
- * Treatment options for this aggressive cancer include surgery and chemotherapy (like cisplatin), with some patients showing positive responses to targeted therapies; a case study highlighted successful surgical treatment for a patient with advanced disease.

Article Synopsis
- * This case study details a female patient misdiagnosed with cervical adenocarcinoma, who eventually underwent multiple surgeries and chemotherapy after being correctly identified with urachal adenocarcinoma that spread to the bladder and vagina.
- * The findings emphasize the need for thorough histopathological evaluation for accurate diagnosis and suggest that anterior pelvic exenteration may be an effective treatment for local recurrences of UrC, although more research is needed.

Introduction: Urachal carcinomas are uncommon malignant neoplasms comprising only 0.01% of all adult cancers. Most patients were aged from 58 to 64 years at diagnosis with 60 years being the median.
