BREAST, LEFT (ADDITIONAL DEEP MARGIN) , EXCISION: - BENIGN BREAST TISSUE. - NEGATIVE FOR MALIGNANCY. COMMENT. PART A. The tumor exhibits a lobular growth pattern, which is confirmed by an. E-cadherin immunohistochemical stain. However, focal tubular formation is. noted in scattered portions of tumor. Based on morphologic and. immunohistochemical features, the tumor type is interpreted as being. infiltrative lobular carcinoma with focal ductal differentiation. Assessment of the greatest dimension of tumor size is hindered by. the multifocal nature of the infiltrating lobular carcinoma. The greatest. dimension of 2.3 CM is based on the combination of microscopic and. radiographic findings in this case. PART C. The tumor exhibits features that are similar to those features seen in the. tumor in Part A. This case received intradepartmental consultation. Previous biopsy material. was reviewed in conjunction with this. case. CLINICAL DIAGNOSIS AND HISTORY: y/o female with history of left breast mass. PRE-OPERATIVE DIAGNOSIS: none provided. Specimen #: POST-OPERATIVE DIAGNOSIS: none provided. GROSS DESCRIPTION: A: Received fresh, labeled with the patient's name. and. designated "Left Breast Lumpectomy" is a breast lumpectomy specimen with. accompanying radiograph, measuring 6.0 cm from superior to inferior, 3.5. cm from medial to lateral, and 2.0 cm from anterior to posterior. A. 4.0. x. 0. 6 cm lightly pigmented, loosely adherent skin ellipse is noted on the. superficial surface. The specimen is inked as follows superior - blue;. inferior - green; medial - red; lateral - yellow; anterior - orange;. posterior - black. Serial sectioning reveals a 1.5 x 1.0 x 0.6 cm poorly. defined mass. The cut surface is tan-white, firm and focally congested. with an embedded metallic clip. The mass is located 0.5 cm from the. anterior, medial, and posterior margins, and 0.7 cm from the lateral. margin. The remainder of the specimen is composed of markedly dense. tan-white fibrous tissue admixed with a minimal amount of adipose tissue. Entirely submitted. Cassette Summary : Al-anterior-lateral margin with skin. A2-posterior-medial margin. A3-posterior-lateral margin. A4-posterior margin. A5-mass. A6-mass in relation to deep margin. A7 through A16 - remaining serial sections from superior to inferior, with. matched plane sections in A10-A11 and A12-A13. B: Received fresh, labeled with the patient's name. and. designated "Sentinel Node #1" is a single 2.0 x 1.5 x 0.7 cm pink-tan -. lymph node. The specimen is trisected and submitted in cassettes B1-B2. A matched section of B1 is submitted in. for CBCP protocol. C: Received in formalin, labeled with the patient's name,. and designated "Additional Superior Margin" is an irregular. fragment of pale yellow adipose tissue measuring 5.2 x 2.9 x 1.0 cm in. overall dimensions. Several metallic staples are present embedded on one. surface of the specimen; this surface is designated as the new true. margin. This surface will be inked orange and the opposing surface will. be inked blue. The specimen is serially sectioned to reveal a dense. tan-white fibrous cut surface. Residual tumor is not grossly identified. The specimen is entirely and sequentially submitted in eight cassettes. scfns. D: Received in formalin, labeled with the patient's name,. Specimen #: 3. GROSS DESCRIPTION (continued) : and designated "Additional Deep Margin" is an irregular fragment. or tan-yellow lobulated adipose tissue measuring 2.3 x 1.2 x 0.6 cm in. overall dimensions. Several metallic staples are identified embedded in. one surface of the specimen; this surface is identified as the true new. margin. This surface is inked orange, and the opposing surface is inked. blue. The specimen is serially sectioned to reveal a homogeneous. tan-yellow cut surface without evidence of residual tumor. The specimen. is entirely and sequentially submitted in three cassettes.

final output (tokens=2160) : 
 The breast pathology report suggests the presence of infiltrating lobular carcinoma with focal ductal differentiation, Nottingham grade II (moderately differentiated), and a tumor size of 2.3 cm. No necrosis or definitive evidence of vascular invasion was found. Microcalcifications were present along with intraductal component: lobular carcinoma in situ. The tumor was found to be positive for estrogen receptors and progesterone receptors, while HER-2 by IHC was negative. Lymphovascular invasion and ancillary testing results were not observed.
