Incidence and patterns of recurrence of prostate cancer on surveillance prostate biopsy following focal therapy with nanoknife

Abstract

Clinical history of extramammary malignancy was provided for most patients (82%, 18/22). Two cases were initially misdiagnosed as invasive breast carcinoma, before further clinical history was provided to the reporting pathologist. Conclusions: The most important factor allowing correct classification of a non-mammary metastases to breast is the provided clinical history. Breast involvement as initial presentation can occur but is rare. It is imperative for pathologists to differentiate between metastatic and primary tumours of the breast because the treatment and prognosis differ considerably.
