prompt1 : extract information from  breast pathology report. List the histological classification, i.e. type of cancer or DCIS, subtype, description of any necrosis, any mention of tumor infiltrating lymphocytes,  histological grade, nuclear grade,  lymphovascular invasion, calcification, receptor status, IHC and any other ancillary testing results.  List out and expand the main points.
prompt2 : The report is - Subtype Basal, Final diagnosis. Breast, left, simple mastectomy: Medullary carcinoma forming a 4.5 x 2.0 x 2.0 cm well. circumscribed mass (AJCC p T2) in the upper outer quadrant associated with prior biopsy site. The surgical margins are widely negative. Seen with Dr. Lymph nodes, left axillary sentinel, excision: Multiple (5) left axillary sentinel lymph nodes are. negative for tumor. Blue dye is not identified in any of the five left axillary sentinel lymph nodes. (AJCC pN0(i-)). Immunohistochemical cytokeratin stain was performed on the paraffin. embedded sentinel lymph node tissue and confirms the H&E impression.

expanded version (tokens=561) : 
 Histological Classification: The type of cancer identified in the report is medullary carcinoma which is a rare subtype of invasive ductal carcinoma. It is categorized under the basal subtype of breast cancer.

Subtype Description: It is described as a well-circumscribed mass measuring 4.5 x 2.0 x 2.0 cm in size in the upper outer quadrant of the left breast. 

Necrosis: No mention of any necrosis is reported.

Tumor Infiltrating Lymphocytes: There is no mention of tumor infiltrating lymphocytes in the report.

Histological Grade: The histological grade is not mentioned in the report.

Nuclear Grade: The nuclear grade is not mentioned in the report.

Lymphovascular Invasion: The report does not mention any evidence of lymphovascular invasion.

Calcification: The presence or absence of calcifications is not reported.

Receptor Status: There is no mention of estrogen receptor (ER), progesterone receptor (PR) or human epidermal growth factor receptor 2 (HER2) status in the report.

IHC and Ancillary Testing Results: An immunohistochemical cytokeratin stain was performed on the paraffin-embedded sentinel lymph node tissue which confirmed the presence of cancer cells. The surgical margins are widely negative and there is no evidence of cancer found in the five left axillary sentinel lymph nodes. 

Overall, the report identifies a rare subtype of breast cancer known as medullary

prompt : Please generate a succinct report in 75 words from the above information. Exclude any filler words or sentences. If something is not mentioned or specified, exclude it from the report. Low verbosity.

final output (tokens=698) : 
 The pathology report identifies medullary carcinoma, a rare basal subtype of invasive ductal carcinoma, forming a well-circumscribed mass in the upper outer quadrant of the left breast. No necrosis or lymphovascular invasion is observed. Histological grade and receptor status are not mentioned. Surgical margins show no cancer while sentinel lymph nodes are negative for tumor with confirmed cytokeratin stain. Five lymph nodes assessed do not show blue dye identification.
