A Rare Case of Esophageal Adenocarcinoma with Urinary Bladder Metastasis

الملخص EN

Metastatic esophageal adenocarcinoma to the urinary bladder is extremely rare.

We describe a previously healthy 49-year-old female with recent diagnosis of adenocarcinoma of the gastroesophageal junction with metastatic disease to the liver.

Biopsy was positive for human epidermal growth factor receptor 2 (HER2) by Fluorescence In Situ Hybridization (FISH).

She received six cycles of Cisplatin, 5-Fluorouracil, and Herceptin and subsequently developed symptomatic anemia and hematuria.

Cystoscopy with retroflexion was performed and she received a transurethral resection of bladder tumor with fulguration.

Pathology of the bladder tumor revealed similar morphology to her liver metastasis and immunohistochemical stains were consistent with metastatic esophageal cancer.

Three weeks after being diagnosed with metachronous urinary bladder metastasis from esophageal adenocarcinoma primary, she expired.

She only received her first cycle of palliative chemotherapy with Ramucirumab and Paclitaxel.
