Comment: Three distinct masses were identified in the mastectomy. specimen, all located in the lower outer quadrant. The two larger masses. (#1 and #2) are histologically similar, showing a poorly differentiated. epithelial component as well as a mesenchymal component displaying marked. pleomorphism and fascicles of spindled cells. Staining of these biphasic. areas show strong pancytokeratin positivity in the epithelial component. while the spindled areas are negative. The histologic and. immunohistochemical pattern is consistent with metaplastic carcinoma. with a malignant sarcomatous component (carcinosarcoma) . While. mass. #1. and #2 are morphologically similar, they are not grossly or histologically. contiguous. The third mass (#3) is a different histologic type (adenoid. cystic carcinoma) It is also grossly separate from masses #1 and #2. As. per the AJCC Cancer Staging Manual, the grade and stage of multiple tumors. of different histologic grade and/or type is based on the largest tumor. Specimen #: FINAL DIAGNOSIS (continued) : (mass #1) , as reflected above. Mass #3 is weakly ER positive (<5% of tumor. nuclei staining), PR negative, and Her- neu negative (1+ staining) . This case received intradepartmental peer review. References: Edge SB., Byrd DR, Carducci MA, Compton CC, eds. AJCC Cancer Staging. Manual. 7th ed. New York, NY: Springer; 2009.

Axillary Sentinel Node" and consists of a 2.5 x 2.0 x 0.8 cm irregular. portion of yellow-tar soft tissue. Sectioning reveals two pink-tan lymph. nodes measuring 1.5 x 1.5 x 0.8 cm and 2.0 x 1.0 x 0.4 cm. Each lymph. node is trisected to reveal a pink-tan cut surface that is otherwise. unremarkable. The lymph nodes are entirely submitted as follows. A1: first described lymph node. A2: second described lymph node. B. The specimen is received in formalin, labeled with the patient's. designated "Right Axillary Sentinel Node #3" and. consists of a pink-gray lymph node measuring 2.0 x 1.5 x 0.6 cm. The. lymph node is trisected to reveal an unremarkable cut surface. The. specimen is entirely submitted in two cassettes. The specimen is received in formalin, labeled with the patient's. è designated "Right Breast" and consists of a right. mastectomy oriented with a short stitch superior and long stitch lateral. The specimen measures 21.0 cm from medial to lateral, 21.0 cm from. superior to inferior and 4.0 cm anterior to posterior. The darkly. pigmented superficial skin ellipse measures 6.2 x 4.5 cm and displays a. centrally located everted nipple measuring 1.0 cm in diameter. No. discharge is noted. No scars are noted. The specimen is inked as. follows: deep margin = black. superior surface of the lower outer quadrant = blue. Upon sectioning the cut surface is composed predominantly of yellow-tan. lobulated adipose tissue admixed with approximately 20% dense pink-white. fibrous tissue which is predominantly located in the central breast. Two. discrete masses are identified in the lower outer quadrant. Mass #1.

 Some important information from the breast pathology report includes:

- Type of cancer: Mixed epithelial/mesenchymal metaplastic carcinoma (carcinosarcoma) and adenoid cystic carcinoma
- Histologic grade: Grade 3, poorly differentiated
- Tumor size: 2.5 cm in the dominant mass (#1)
- Margins: Negative for invasive carcinoma and DCIS
- Lymphovascular invasion: Not identified
- Calcification: Present within invasive and in situ carcinoma
- Receptor status: Estrogen receptor and progesterone receptor positive, HER2 neu negative
- Ancillary testing results: Intraductal papilloma, weak ER positivity (<5% of tumor nuclei staining), intermediate PR positivity (5% of tumor nuclei staining), negative HER-2 neu by IHC (score 1+) 

It is also important to note that three masses were identified in the mastectomy, with mass #1 and #2 being morphologically similar but not grossly or histologically contiguous. The third mass (#3) is a different histologic type (adenoid cystic carcinoma) and is grossly separate from masses #1 and #2. The grade and stage of multiple tumors of different histologic grade and/or type are based on the largest tumor, which is reflected as mass #1 in this case. Additional information related to lymph nodes, specimen integrity, tumor focality, and treatment effect is also provided in the report.

final output (tokens=3019) : 
 Mixed epithelial/mesenchymal metaplastic carcinoma (carcinosarcoma) with adenoid cystic carcinoma was identified in the right breast measuring 2.5 cm in size and classified as poorly differentiated grade 3. Necrosis was present within DCIS, and calcifications were identified within invasive and in situ carcinoma. Estrogen and progesterone receptors were positive, while HER2 neu was negative by IHC testing. No lymphovascular invasion was found. Sentinel lymph nodes were negative for malignancy on routine and immunohistochemical stains.
