Abstract:
"Flare" phenomenon has been primarily reported as a transient increase in the number or intensity of lesions on bone scans in patients receiving hormonal or chemotherapy. It has been well documented in patients with metastatic breast or prostate carcinoma, and recently reported in those with lung cancer. We present a case of bone metastasis from bladder carcinoma, in which healing flare phenomenon was observed after radiotherapy.
