Clinical History: The patient is a. -year-old female who presented with an abnormal screening. mammogram on. that revealed a large area of pleomorphic calcifications. biopsied as ductal carcinoma in situ, high grade, solid type with central. necrosis. Left breast MRI on. evealed segmental clumped non-mass. enhancement with mixed kinetics measuring 10.2 X 5.4 x 2.5 cm associated with a. lateral biopsy clip. A 0.7 x 1.0 X 1.0 cm mass with washout kinetics, suspicious. for invasive component was seen just posterior to the biopsy clip. The patient. undergoes simple mastectomy, sentinel lymph node biopsy and breast. reconstruction. Specimens Received: A: Left sentinel lymph node #1. B: Sentinel node #2 left axilla. C: Left breast. Gross Description: The specimens are received in three containers each labeled with the patient's. name and medical record number. A. The first container is additionally identified as, 'left sentinel node #1'. Received fresh for intraoperative diagnosis is a 4.0 X 2.0 x 1.0 cm segment of. tan-pink fibrofatty tissue that is dissected for lymph node candidates. Frozen. section diagnosis is 'lymph node, no tumor' per. . The frozen section. remnants are entirely submitted in cassettes A1 FS and A2 FS. The remaining. tissue is entirely submitted in cassettes A3 and A4. B. The second container is additionally identified as, 'sentinel node #2, left. axilla'. Received fresh for intraoperative diagnosis is a 3 X 2.0 X 2.0 cm. segment of tan-brown rubbery tissue grossly consistent with a lymph node. The. cut section reveals an unremarkable surface. The entire lymph node is frozen. Post section diagnosis is 'lymph node, no tumor' for. : The frozen. section remnant is entirely submitted in cassette B1FS. C. The third container is additionally identified as, 'left breast'. Received. fresh and placed in formalin is a 2640 gm mastectomy specimen measuring 32.5 cm. from medial to lateral, 32.5 cm from superior to inferior and 5.3 cm from. anterior to posterior. There is 80 cm long by 0.7-6.5 cm wide tan-brown,. wrinkled skin ellipse on the anterior surface, with ashort suture designating. the superior pole and a long suture designating the lateral pole. The areola. measures 5.5 X 3.5 cm areola and the nipple 1.5 cm in diameter. The nipple. areolar complex displays no evidence of ulceration or retraction. No axillary. tail is present with the specimen. The deep surface is inked black, the. anterior-superior surface blue and the anterior-inferior surface green and the. breast is serially sectioned from medial to lateral into 11 slices. There is a. 1.1 x 0.9 X 0.8 cm, gray-tan mass in slices 7 and 8, 5.5 cm from black ink and. 2.0 cm from blue ink. A metallic clip is identified in slice 7. A 1.5 cm. (greatest dimension) biopsy site is identified, adjacent to the lesion, with a. probable metallic clip (vs. staple) within the node. Additional masses or. nodules are not noted. Representative sections are submitted as follows: C1-8: Representative sections of lesion, slice 7 and 8 (clip in C1, C3. closest approach to blue ink). C9: Intramammary lymph node, adjacent to mass, bisected. C10: Representative slice 6, medial to mass. C11: Representative slice 9, lateral to mass. C12: UOQ, slice # 10. C13: UIQ, slice # 3. C14: LOQ, slice # 9. C15: LIQ, slice # 2. C16: Representative skin. C17-18: Nipple. Tissue fixed for at least 6 hours in 10% NBF and no more than 72 hours.
