Tissue is procured. Representatively submitted in 18 cassettes as per the attached diagram: B1: slice 1 entire, perpendicular sections of the medial margin. B2: slice 2, representative anterior margin. B3: slice 3, representative posterior margin with the mass. B4-B5: slice 4, sections of the mass showing the closest posterior margin,. B6-B7: slice 5, mass with anterior and posterior margins. B8: slice 5, superior margin. B9-B10: slice 6, mass with anterior and posterior margins. B11: slice 6, inferior margin.

final output (tokens=2026) : 
 The report indicates left medial breast excision with intraductal papilloma, apocrine metaplasia and columnar cell changes. Left breast excision revealed 2.3cm invasive ductal carcinoma, basal subtype, with necrosis and SBR grade 3. Sentinel lymph nodes were negative for metastatic carcinoma. ER, PR negative while HER2 negative by FISH. Surgical margins were clear in both the excisions. Lymphovascular invasion was not identified and multifocality was absent. Pathological staging: pT2N0.
