expanded version (tokens=1876) : 
 The pathology report details the findings of a left breast lumpectomy, sentinel node biopsy, and axillary node dissection. The main findings are:

- Histological classification: invasive, poorly differentiated mammary carcinoma, high nuclear grade.
- Size: greatest dimension of the largest focus of invasion is 2.5 cm.
- Margins: uninvolved by invasive carcinoma. Distance from closest margin is 2mm (posterior).
- Lymphovascular invasion: not identified.
- Tumor focality: single focus of invasive carcinoma.
- Histologic grade: overall grade is 8 (3+3+2).
- Immunohistochemistry: tumor cells have been reported to be ER and PR negative, and HER2 negative by CISH. In-house immunostains are pending for further subclassification.
- Lymph nodes: three sentinel nodes were examined, and no carcinoma was seen in any of them. No lymph node metastasis was identified.
- Additional pathologic findings: no DCIS or LCIS was identified. Dermal lymphovascular invasion was not present. Other ancillary studies performed on another specimen have shown negative ER, PR, and HER2 status.
- Intraoperative consultation: no carcinoma was seen in sentinel node #1 and suspicious node by FS (frozen section). 

Overall, the report indicates the presence of invasive mammary carcinoma with high nuclear grade but uninvolved margins. The tumor has been subtyped as ER/PR negative and HER
