prompt2 : The report is - Subtype Basal, DEPARTMENT OF PATHOLOGY AND LABORATORY MEDICINE. Date Col]. SPECIMEN. A. Left axillary sentinel lymph node. B. Left breast. CLINICAL NOTES. CLINICAL HISTORY: A -year-old with left breast metaplastic. cancer. FROZEN SECTION DIAGNOSIS. AFS Left axillary sentinel node, excision: No evidence of metastasis in 1 node (0/1). GROSS DESCRIPTION. A. Received in a container labeled with the patient's name,. medical record number and "left axillary sentinel lymph. node" The specimen container holds a single soft tan lymph node. measuring 1.5 x 1 x 0.5 cm. AS block ASF, bisected. B. Container B is labeled with the patient's name, medical. record number and "left breast". The specimen consists of. an excisional biopsy oriented by two sutures and measuring 3.5 cm. from anterior to posterior, 3.8 cm. from superior to inferior and. 2.5 cm. from medial to lateral. The specimen margins are inked. as. follows: blue-interior, black-posterior, red-superior,. green-inferior, vellow-medial, orange-lateral. The specimen is. serially sectioned and there is a firm, tan stellate lesion. measuring 1.8 x 1.5 x 1.5 cm., located extending in the direction of. the inferior margin of resection and appearing to involve the. inferior margin. ASB1-B20. MICROSCOPIC DESCRIPTION. A. There is no evidence of metastasis in one left axillary. sentinel lymph node. The node is examined by multilevel. sectioning with H&E staining, as well as for immunohistochemistry. for pankeratin. B. Invasive Carcinoma: Present. Histologic type: Adenocarcinoma with squamous differentiation,. metaplastic. Histologic grade: Overall grade: 3. Architectural score: 3. Nuclear score: 3. Mitotic score: 3. Greatest dimension (pT) : 1.8 cm (pT1). Specimen margins: Positive. Vessel invasion: Invasive carcinoma involves inferior margin over. a distance of greater than 1 cm. Vessel invasion: foci suspicious. Calcification: Present. Ductal carcinoma in situ: Present. Histologic pattern: Solid. Nuclear grade: 3. Central necrosis: Present. % DCIS subtotal tumor: Less than 10%. Extensive intraductal component: Absent. Specimen margins: Negative. Calcification: Present. Description of non-tumorous breast: Unremarkable. Comments: None. Prognostic markers: Previously FISH for HER-2 was reported as. equivocal and a block is sent at the request of. repeat HER-2 by FISH. DIAGNOSIS. A. Left Axillary sentinel lymph node, resection: No evidence of metastasis in one lymph node (0/1). B. Left breast, excisional biopsy: - Poorly differentiated carcinoma with metaplastic features,. grade 3,. 1.8 cm. Invasive carcinoma extends to involve the inferior margin. of resection.

final output (tokens=1303) : 
 Left axillary sentinel lymph node: No evidence of metastasis. Left breast, excisional biopsy: Invasive adenosquamous carcinoma with squamous differentiation and metaplasia, histologic grade 3, 1.8 cm in dimension (pT1). Ductal carcinoma in situ has solid and comedo subtypes, nuclear grade 3 with central necrosis. Specimen margins are positive on the inferior margin over a distance of greater than 1 cm. Vessel invasion is suspicious with present calcification. HER2 FISH previously reported equivocal.
