目前,一般认为定向的细针抽吸活检(FNAB)与切削针吸活检为乳癌的两种精确、快速、安全且经济的诊断方法。作者报道1例67岁病人左乳内下象限有一直径18mm病变,细针抽吸活检诊为良性病变,为进一步明确诊断而行定向切削活检,使用14号大针芯活检针,乳腺摄片示针横穿病变,术后有小出血,活检结果为浸润性导管癌。2周后手术切除病变及活检通道,组织病理学检查示肿瘤边缘清晰,活检出血区含铁血黄素沉着位于肿瘤边缘。
At present, it is generally believed that targeted fine needle aspiration biopsy (FNAB) and cutting needle aspiration biopsy are two precise, rapid, safe, and economical diagnostic methods for breast cancer. The authors reported a 67-year-old patient with a 18-mm lesion in the left breast and lower quadrant of the left breast. The fine-needle aspiration biopsy was diagnosed as a benign lesion. Directional biopsy was performed for further definitive diagnosis, and a large-needle core biopsy needle No. 14 was used. The needle traverses the lesion and there is a small postoperative bleeding. The biopsy result is invasive ductal carcinoma. After 2 weeks, the lesions and biopsy channels were resected. Histopathological examination showed that the edges of the tumors were clear, and hemosiderin in the biopsy hemorrhage area was located at the edge of the tumor.
