Résumé :

Patients treated with bladder augmentation have a higher risk of developing bladder cancer than the general population. In these patients, tumours are most frequently primary bladder cancers. Metastasis in an augmentation cystoplasty is extremely rare and here we describe the first case of metastasis from lobular breast carcinoma in an ileal patch. A 52-year-old woman, with a medical history of invasive lobular breast cancer, presented with gross hematuria seven years after an ileal augmentation cystoplasty. A large bladder mass was found exclusively on the enteric patch, with lymphadenopathies from iliac vessels to right kidney hilum. Asurgical resection of the ileal segment with trigonal preservation was performed, associated with a complete cytoreduction. The bladder was reconstructed with a new ileal segment. Pathology confirmed the diagnosis of metastatic lobular breast carcinoma. Patients treated with augmentation cystoplasty need a close and long follow-up to detect the warning signs of tumor development. We herein report our experience of a metastatic lesion on the enteric part of a cystoplasty. Unusual characteristics of the bladder tumor and personal oncologic history of the patient may be suggestive of a secondary lesion.
