Primary Signet-Ring Cell Adenocarcinoma of the Urinary Bladder Treated with Partial Cystectomy: A Case Report and Review of the Literature

الملخص EN

Primary signet-ring cell carcinoma is a variant of adenocarcinoma which is extremely rare, associated with poor prognosis and generally found to be resistant to chemotherapy and radiotherapy.

We report a case of primary signet-ring cell carcinoma of the bladder which was successfully treated with partial cystectomy.

A 71-year-old female with a history of type 2 diabetes, hypertension, and ischaemic heart disease presented with painless haematuria for 2 months’ duration.

The abdominal ultrasonography showed a localised polypoidal vesical growth arising from the bladder dome.

Cystoscopy revealed an exophytic solid tumour in the anterior fundal wall.

A deep transurethral resection of bladder tumour was done and histology revealed an adenocarcinoma composed of mucinous and signet-ring cell components.

Later, considering the patient’s age and the poor general condition, a partial cystectomy was done.

Follow-up cystoscopy and ultrasonography were done at 12 months and there was no evidence of tumour recurrence and the patient is currently symptom-free.

Partial cystectomy may be considered in patients with localised tumour without evidence of metastasis and poor general condition.

Regular cystoscopies and ultrasound imaging are necessary for follow-up and early identification of recurrences.
