ONE REACTIVE LYMPH NODE (0/1). Lab No.: C. SENTINEL LYMPH NODE #3 -. ONE REACTIVE LYMPH NODE (0/1). D. LEFT BREAST MASTECTOMY -. INVASIVE LOBULAR CARCINOMA (7 CM.). TUMORAL CALCIFICATION/NECROSIS: NONE IDENTIFIED. DCIS/LCIS: NONE IDENTIFIED. SURGICAL MARGINS/NIPPLE, SKIN AND AREOLA: UNINVOLVED. NON-NEOPLASTIC BREAST: FIBROCYSTIC CHANGES TO INCLUDE DUCTAL EPITHELIAL. HYPERPLASIA. PTNM CLASSIFICATION: T3 N1 MX; STAGE IIIA. COMMENT: The multiple sections from the tumor reveal patchy areas of tumor infiltration. extending up to lactiferous ducts. In addition, the tumor cells also display unfavorable. nuclear features in many areas. The ER, PR and Her-2/neu have been performed on the. previous biopsy. The PanKeratin Immunostain is performed on specimens A, B. and C. GROSS: A. The container is received fresh unfixed labele. eft sentinel lymph node #1. for frozen section". The specimen consists of an ovoid mass of pink-tan soft rubbery. tissue mixed with fatty tissue measuring 0.6 cm. in greatest dimension. Frozen section is. obtained by. The entire specimen including frozen section in one block. B. The container is received fresh unfixed labele. left sentinel lymph node #2. for frozen section". The specimen consists of an ovoid mass of tan-gray soft rubbery. tissue with attached fat. Frozen section is obtained by. The entire specimen. including frozen section in one block. Lab No.: C. The container is received fresh unfixed labele. sentinel lymph node #3 for. frozen section". The specimen consist of an ovoid mass of pink-tan soft rubbery tissue. measuring 1.3 cm. in diameter in the aggregate. Frozen section is obtained by. The entire specimen including frozen section in one block. D. The container is received fresh unfixed labeled. "left breast". The specimen. consists of an 809 gm. apparent left breast which is 23 x 15 x 4 cm. in greatest overall. dimension. There is an inverted nipple. The attached skin ellipse is 21 x 9.5 cm. Sectioning through the breast stroma reveals dense gray-white fibrous tissue varying up. to 7.5 cm. in greatest dimension. This area has been previously marked with blue dye. There are scattered cystic spaces varying up to 0.1 cm. in greatest dimension filled with. an amber-colored fluid. Sectioning also reveals a firm tan-gray striated tumor mass. which is 7 x approximately 5.5 cm. in greatest overall dimension and is approximately. 0.7 cm. from the deep/underlying resection margin. The specimen is submitted in ten. blocks. Key Note Block Summary: 1-nipple, 2 through 4-cystic spaces, 5-random,. 6. through 10-tumor mass. MICROSCOPIC EXAMINATION: MICROSCOPIC EXAMINATION CONDUCTED BY PATHOLOGIST CONFIRMS FINAL DIAGNOSIS. SPECIAL STAINS PERFORMED: PanKeratin (specimens A,B,C).

Main points: 
-The patient underwent left simple mastectomy with sentinel lymph node biopsy for invasive lobular carcinoma.
-The frozen section diagnosis of the sentinel lymph nodes revealed one positive lymph node (#1) out of three, with no pericapsular soft tissue extension.
-The final diagnosis confirms the presence of invasive lobular carcinoma in the breast.
-The ER, PR, and HER2 status of the tumor were already determined on a previous biopsy and reported as Luminal A subtype (ER/PR positive, HER2 negative). 
-Unfavorable nuclear features noted in some areas of the tumor. 
-No lymphovascular invasion or tumor necrosis identified.
-Surgical margins, nipple, skin, and areola were uninvolved. 
-Non-neoplastic breast tissue showed fib

final output (tokens=1639) : 
 The patient underwent left simple mastectomy with sentinel lymph node biopsy for invasive lobular carcinoma. The tumor was confirmed as Luminal A subtype (ER/PR positive, HER2 negative) with unfavorable nuclear features noted in some areas. No necrosis was identified, and surgical margins were uninvolved. Non-neoplastic breast tissue showed fibrocytic changes including ductal epithelial hyperplasia. Sentinel lymph nodes showed one positive node out of three with no pericapsular soft tissue extension. PanKeratin immunostain was performed, and no lymphovascular invasion or calcification was identified.
