A Case of Recurrent Breast Cancer with Solitary Metastasis to the Urinary Bladder

Abstract EN

Elderly patients with breast cancer often present with symptomatic, locoregionally advanced rather than screening-detected disease, thereby increasing the risk of metastatic recurrence during their remaining life time.

Typical sites of metastases include lungs, bones, liver, and brain.

Here we present a patient who developed a solitary urinary bladder metastasis five years after primary diagnosis of stage T4 N0 estrogen receptor-positive lobular carcinoma, while on continued adjuvant endocrine treatment (91 years of age).

Anemia and increased serum creatinine resulting from hydronephrosis led to diagnosis of metastatic disease, which was confirmed by transurethral resection.

The patient responded clinically to palliative radiotherapy and a different type of endocrine therapy.

One year after diagnosis of metastatic disease, she died without signs of cancer progression.
