Effective. this Checklist utilizes the 7th edition TNM staging. system for breast of the American Joint Committee on Cancer (AJCC) and the. International Union Against Cancer (UICC). Clinical History: The patient is a year old female with a history of invasive lobular carcinoma. grade 2 of 3 and lobular carcinoma in-situ of the right breast. She undergoes. right simple mastectomy and sentinel lymph node biopsy. Comment. C. CKAE1/AE3 is negative in the skin section with scar. Myosin heavy chain. performed on C12 reveals absence of a myoepithelial cell layer supporting. invasive carcinoma. Specimens Received: A: Right axillary sentinel node #1. B: Right axillary sentinel node. C: Right breast. D: Skin; biopsy. Gross Description: Received are four containers, each labeled with the patient's name and medical. record number. A. Container A is further designated '1. Right axillary sentinel node #1. Received fresh for frozen section diagnosis is a 3 X 1.5 X 1 cm lymph node which. is bisected and entirely frozen. Frozen section diagnosis is 'one lymph node. negative for tumor' by Dr. The frozen section remnant is submitted. entirely in cassettes A1-A2FS. B. Container B is further designated '2. Right axillary sentinel node #2. Received fresh and placed in formalin is a 0.9 X 0.8 x 0.4 cm blue lymph node. which is submitted entirely incassette B1. C. Container C is further designated '3. Right breast, double short stitch. superior, double long stitch lateral.' Received fresh is a 1,259 gm mastectomy. specimen measuring 30 cm from medial to lateral, 21 cm from superior to. inferior, and 8 cm from anterior to posterior. There is a short stitch marking. the superior edge and a long stitch marking the lateral edge. There is a 25.5 x. 14.5 cm ellipse of pink-tan skin with a 4.1 cm areola and a 1.1 cm nipple. The. anterior-superior margin is inked in blue, the anterior-inferior margin is inked. in green, and the posterior/deep margin is inked in black. The specimen is then. sliced into 16 slices with slice #1 being the most lateral slice. In slices. 9-10 at the 9:30 to 10:30 position is a main mass measuring 4.4 X 4 X 2.6 cm. The mass extends to 2 cm from the inked, black margin. In addition at the 8:30. position in slices 7-8 there is a 2 X 1.5 X 1 cm mass which is 6 cm from the. inked, black margin and 0.4 from the inked green margin. In slice 15 at the 4. o'clock position there is a 1 X 1 X 0.5 cm firm, white nodule which is 0.5 cm. from the inked, green margin and 3 cm from the inked, black margin. The nipple. is amputated, bisected and submitted entirely in cassette C1. the skin. surrounding the tissue just deep to the nipple are submitted in cassette C2. At. 6 cm lateral to the nipple is a 0.5 X 0.3 cm slightly raised area of skin which. is the same, pink-tan color as the surrounding skin. This is submitted in. cassette C3. Representative sections are submitted as follows: C4: lesion from slice 7. C5: lesion from slice 8. C6-C7: mass from slice 9 with the black ink in C6. C8: additional representative section of mass from slice 9. C9-10: mass from slice 10 with the inked blue margin in C9 (grossly tumor is. only in C10). C11: scar like area from slice 15. C12: scar like area from slice 15. In the superior area of slices 13-14 is a 3 x 2 X 2 cm vaguely nodular area. dense, white-tan parenchyma. This area is 1.5 cm from the inked, blue margin. and 3 cm from the black margin. C13: vaguely nodular area from slice 13. C14: vaguely nodular area from slice 14. C15: representative section from the upper-outer quadrant from slice 3. C16: representative section from the lower-outer quadrant from slice 5. C17: representative slice from the upper-inner quadrant from slice 16. C18: representative section from lower-inner quadrant from slice 14. D. Container D is further designated '4. Skin; biopsy.' Received fresh and. placed in formalin is a 14 gram, 4 X 2.5 cm ellipse of pink-tan skin with a. central 1.9 X 0.9 cm defect. It is excised to a depth of 1 cm. The deep margin. is inked black. The circumferential margin is inked blue. The specimen is. serially sectioned to reveal yellow, lobular unremarkable subcutaneous adipose. tissue. Representative sections are submitted in cassettes D1-D2. M.D. Pathologist Sign Out:

final output (tokens=2355) : 
 A year-old female with invasive lobular carcinoma (sub-type LumA), underwent right simple mastectomy. Intraductal hyperplasia, usual type, ectatic ducts and apocrine metaplasia were observed. The cancer was SBR grade II. Lymphovascular invasion was highly suspicious. ER had moderate expression in > 75% of invasive tumor nuclei whereas PR showed strong expression in > 90%of invasive tumor nuclei. Her2/neu antigen(IHC) showed an equivocal value of 2+. Her2/neu antigen (FISH) test is pending on block C7 (9:30 to 10:30 position).
