Renal Cell Carcinoma Diagnosis After Initial Detection on Screening Mammogram.

Renal cell carcinoma (RCC) defines a varied class of primary renal neoplasms which arise from the renal cortex. Because RCC often progresses silently to a very advanced metastatic stage, the majority of RCC cases are diagnosed either incidentally on abdominal imaging or upon presentation of invasive disease at metastatic sites. This case profiles a 57-year-old woman with distant history of resected RCC who presented with a posterior breast mass that was diagnosed as metastatic recurrence of RCC through mammogram, ultrasound, and core biopsy.

Detection of a Mammographically Occult Breast Cancer with a Challenging Clinical History.

Screening mammography has helped to identify countless incidences of breast cancer since its adoption in the 1960s. Over time, the screening guidelines and techniques have been refined to better detect malignancies and to avoid false positive results. However, weaknesses remain in mammography and represent an opportunity for improvement.
