CLINICAL HISTORY: Left breast cancer. FROZEN SECTION DIAGNOSIS. FSA) Left sentinel node - Two of three lymph nodes positive for. metastatic carcinoma (2/3). GROSS DESCRIPTION. A. Submitted fresh for frozen section as "left sentinel. node" are two portions of fatty tissue, the larger of the. two is 2 cm. in size, the smaller 1.2 cm. in size. The section. through the tissue reveals three small nodules which may be lymph. nodes varying in size from 6 mm. to a centimeter. All three. submitted for frozen section. B. Received fresh, subsequently fixed in formalin labeled. "left breast tissue" is a 7.8 x 7.5 X 4.0 cm. yellow. lobular fatty tissue fragment which is partially covered with a 4.0. X 1.2 cm. pink-tan wrinkled skin ellipse. The specimen has a long. suture designating lateral and a short suture designating superior. The specimen is inked as follows: Superior orange, anterior blue,. posterior black, inferior green and the specimen is sectioned from. medial to lateral to show a yellow lobular fatty cut surface with. minimal fibrous tissue. There is also a white tan firm nodule. which. is centrally located, measuring 3.5 x 2.5 x 2.5 cm. This comes. within 2 cm. of superior-inferior margin and comes within 1.5 cm. of. the anterior and posterior margin. This was located equal distance. between the medial and lateral margins. Representative sections of. the specimen are submitted as follows: Block 1 - representative. GROSS DESCRIPTION. medial margin; block 2 - representative lateral margin; block 3-10. representative sections additional margins and skin. RS-10. C. Received fresh, subsequently fixed in formalin labeled. "axillary content" is a 7 X 6 X 1.5 cm. aggregate of. yellow. lobular fatty tissue fragments which are palpated to identify. possible lymph nodes. Multiple lymph nodes are grossly identified. which range from 0. cm. to 2.0 cm. in greatest dimension. The. lymph nodes are entirely submitted as follows: block 1 - two. possible lymph nodes; block 2 - three possible lymph nodes; block 3. - two possible lymph nodes; block 4 - one possible lymph node. bisected. RS4. MICROSCOPIC DESCRIPTION. A. Sections of the left sentinel lymph nodes demonstrate. metastatic carcinoma involving 2 of 3 lymph nodes. The. largest metastasis is 1.2 cm and extracapsular extension is. present. B. The following template applies to the left breast. Invasive Carcinoma: Present. Histologic type: Infiltrating ductal carcinoma. Histologic grade: Overall grade: 3. Architectural score : 3. Nuclear score: 3. Mitotic score: 3. Greatest dimension: 3.5 cm (pT2). Specimen margins : Negative, nearest 1.3 cm, posteriorly. Vessel invasion: Present. MICROSCOPIC DESCRIPTION. Calcification : Present. Ductal carcinoma in situ: Present. Histologic pattern: Solid and comedo. Nuclear grade: 3. Central necrosis: Present. %DCIS of total tumor: Less than 10%. Extensive intraductal component (present/absent) : Absent. Specimen margins: Negative. Calcification: Present. Description of non-tumorous breast: Proliferative changes. Comments: None. Prognostic markers: Previously performed. C. There is no evidence of metastatic disease present in. 9. additional left axillary lymph nodes. 14, 4x3. DIAGNOSIS. A. Left axillary sentinel lymph nodes, excision: Metastatic carcinoma present in 2 of 3 lymph nodes (2/3) . Size of largest metastasis 1.2 cm. Extracapsular extension present. B. Left breast, excisional biopsy: Infiltrating ductal carcinoma, grade 3, 3.5 cm, margins. negative. Ductal carcinoma in situ, grade 2, margins negative. C. Left axillary contents, resection: No evidence of metastasis in nine lymph nodes (0/9). DIAGNOSIS. M. .D, (Electronic Signature). End Of Report ---.

expanded version (tokens=1401) : 
 Histological classification: 

- Invasive carcinoma: Infiltrating ductal carcinoma 
- Histologic grade: Overall grade 3; Architectural score 3; Nuclear score 3; Mitotic score 3 
- Subtype: Basal 
- Ductal carcinoma in situ: Solid and comedo pattern; Nuclear grade 3; Central necrosis present; % DCIS of the total tumor < 10%; Extensive intraductal component absent 

Description of tumor characteristics: 

- Necrosis: Central necrosis present in ductal carcinoma in situ
- Tumor infiltrating lymphocytes: No mention 
- Lymphovascular invasion: Present 
- Calcification: Present in invasive carcinoma and ductal carcinoma in situ 
- Receptor status: Not mentioned in this report 
- Ancillary testing results: None mentioned 

Other findings: 

- Left axillary sentinel lymph nodes: Two of three lymph nodes positive for metastatic carcinoma (2/3); size of largest metastasis 1.2 cm; extracapsular extension present
- Left axillary contents: No evidence of metastasis in nine lymph nodes (0/9)
- Non-tumorous breast: Proliferative changes 

Overall, the report describes an invasive basal subtype of infiltrating ductal carcinoma in the left breast tissue, with associated ductal carcinoma in situ. The tumor is Grade 3, with necrosis and lymphovascular invasion present, as well as calcifications

final output (tokens=1536) : 
 Report: Left breast tissue excision revealed invasive ductal carcinoma (basal subtype) with associated ductal carcinoma in situ. The tumor is Grade 3, has necrosis and lymphovascular invasion, as well as calcifications. There was positive axillary lymph node involvement with extracapsular extension and no metastasis in the remaining lymph nodes. Non-tumorous breast demonstrated proliferative changes. Receptor status not mentioned.
