Radioactive seed localization is a new procedure for localizing breast lesions that has several advantages over the standard wire-localization procedure. It is reported to be safe for both patients and medical personnel. Although it is theoretically possible to transect the titanium-encapsulated seed while processing the breast specimen in the pathology laboratory, the likelihood of such an event is thought to be exceedingly low. In fact, there are no previous reports of such an event in the literature to date. We recently encountered 2 cases in which a radioactive seed was inadvertently transected while slicing a breast specimen at the grossing bench. In this report, we describe each case and offer recommendations for minimizing radioactive exposure to personnel and for preventing radioactive contamination of laboratory equipment.
放射性粒子定位是一种用于定位乳腺病变的新方法，与标准的金属丝定位方法相比具有许多优势。据报道，该方法对患者和医务人员均安全。虽然在病理实验室处理乳腺标本时有可能横切包裹钛的放射性粒子，但这种事件发生的可能性被认为非常低。实际上，迄今为止，文献中尚无此类事件的报道。我们最近在大体标本台切取乳腺标本时遇到 2 例无意中横切放射性粒子的情况。在本报告中，我们描述了每个病例，并就如何尽量减少人员放射性暴露以及防止实验室设备放射性污染提出了建议。
