prompt2 : The report is - Subtype Basal, DEPARTMENT OF PATHOLOGY AND LABORATORY MEDICINE. Date Coll: SPECIMEN. A. Right axillary sentinel node (hot and blue). B. Right breast. CLINICAL NOTES. PRE-OP DIAGNOSIS: Right breast CA at 1 o'clock position. FROZEN SECTION DIAGNOSIS. A. Benign on frozen section. GROSS DESCRIPTION. A. Received fresh in a container labeled "A. right. sentinel lymph node" is a portion of partially blue stained. fatty tissue containing a soft tan lymph node. The tissue is 3.5 x. 2.5 x 0.8 cm in greatest dimensions. On cut surface, there is tan. lymph node tissue with focal blue staining, without grossly. worrisome area. The specimen is entirely submitted for frozen. section in three blocks. B. Received fresh in a container labeled "right breast" is. a breast resection specimen spanning an area 27 x 28 x 7.4. cm. There is an overlying ellipse of brown skin, 27.5 x 15 cm. The. centrally located areola spans an area 6 x 7 cm, with the nipple. measuring 1.7 x 1.8 x 0.5 cm. On the skin surface there is an area. of scar as well as a 0.2 cm papillary lesion. The deep surface of. the specimen is inked. The breast is serially sectioned, and there. is a 2.3 cm in greatest dimension firm tan-white mass lesion, with. focal changes compatible with reaction to prior biopsy. The. location is compatible with the indicated 1 o'clock position. The. mass is not near the deep margin. The specimen outside of this area. consists of yellow adipose tissue with some interspersed tan tissue. There are no other focal lesions. RS-11, following fixation. BLOCK SUMMARY: B1,B2 - nipple; B3 - skin lesion & skin scar; B4-B6. tumor; B7-B10 - representative breast respectively from upper outer,. upper inner, lower outer, and lower inner quadrants; BRR1 - deep. margin, deep to mass. MICROSCOPIC DESCRIPTION. A. Serial H&E stained sections and immunostains with. antibodies to keratin (AE1-AE3) are examined. There is no. identifiable tumor on H&E stained sections. There are, however,. isolated cells that immunostain with antibodies to keratin (pNO. (i+)]. B. The following template summarizes the findings in this. part: Invasive carcinoma: Present. Histologic type: Invasive ductal carcinoma with metaplastic. features (areas of sarcomatoid carcinoma),. Histologic grade: Overall grade: 3. Architectural score: 3. Nuclear score: 3. Mitotic score: 2. Greatest dimension (pT) : 2.3 cm (pT2). Specimen margins: Negative. Vessel invasion: Not definitively identified. Calcification: Not identified. Nipple (Paget's) : There is lobular neoplasia in the nipple, with. this interpretation supported by diminished immunostaining on an. immunostain for e-cadherin. Ductal carcinoma is not identified. involving the nipple. Invasion of skin or chest wall: Not identified. Ductal carcinoma in situ: Present. Histologic pattern: Solid. Nuclear grade: 3. Central necrosis: Not definitively identified. Extensive intraductal component: Absent. Specimen margins: Negative. Calcification: Not identified. Description of non-tumorous breast: Fibrocystic changes, with. microcalcifications present. Biopsy site changes. There is. a. skin scar. There is also a squamous papilloma in the skin. Lobular neoplasia is also identified in one of the random sections. of breast (block B9). Prognostic markers: Previously performed (see. NOTE: This case has been reviewed in Intradepartmental. Consultation, with concurrence with the interpretation. 4x2,14,15x2,20x2. DIAGNOSIS. A. Lymph node, right axillary sentinel, excision. - No identifiable tumor on H&E stained sections, with isolated. keratin positive cells present [pNO (i+)]. B. Breast, right, excision. - Invasive ductal carcinoma with metaplastic features. (sarcomatoid carcínoma component), see microscopic. description. - Skin and deep margin negative for malignancy. - Lobular neoplasia. - Changes compatible with reaction to prior biopsy. - Fibrocystic changes.
