prompt2 : The report is - Subtype Normal, Patien. CLINICAL HISTORY: Not provided. GROSS EXAMINATION: A. "Right breast biopsy", fresh. The specimen is a 4.5 x 3.5 x 3.0 cm portion. of yellow to grey-white soft tissue. According to the surgeon, the resection. margins are not a concern, as a mastectomy is planned. The specimen is not. inked. Cut surface shows an approximately 2.5 x 2.5 x 1.5 cm mass composed of. firm white tissue with interspersed foci of adipose tissue. The mass extends. to the operative margin over a wide area. The specimen is otherwise composed. of unremarkable adipose tissue. A representative portion of the mass is. submitted for frozen section. Another representative portion is submitted for. hormone receptor analysis. BLOCK SUMMARY: Al frozen section remnant. A2-A4 further representative sections from the mass. B. "Breast tissue right side", fresh. The specimen is a 700 gram, 21 x 14 x 4. cm breast with an attached, approximately 9 x 9 x 1 to 2 cm portion of soft. tissue in the axillary region. The breast includes a 17.5 x 10.5 cm. elliptical portion of skin with a roughly centrally placed nipple and a 4.5 cm. transverse incisional wound located superior, and slightly medial, to the. nipple. The skin is uniformly smooth and tan-white, without erythema,. induration or nodules. The nipple is likewise unremarkable. Cut surface. reveals an approximately 6.0 x 5.0 x 4.5 cm cavity deep to the incisional. wound. The biopsy cavity occupies the region immediately deep to the nipple. and the adjacent upper inner quadrant. An approximately 3.5 x 3.5 x 2.5 cm. mass is present alongside the biopsy cavity, involving tissue medial and deep. to the biopsy cavity. The mass is composed of firm grey-white tissue which. contains foci of yellow adipose tissue within it. The surgical resection. margins are grossly free of the mass; toward the medial edge of the specimen,. the mass extends to approximately 0.3 cm from the deep resection margin, with. questionable extension to within 0.2 cm from the margin at this site. The. breast is otherwise composed of adipose tissue and grey-white glandular-. appearing breast tissue, showing occasional firmer areas of white fibrous-. appearing tissue, but no other discrete masses or nodules. Nine lymph nodes. are identified in the lower portion of the axillary tissue, and nine lymph. nodes are identified in the upper portion of the axillary tissue. The lymph. nodes range up to 3.0 cm in greatest dimensions. Some of the lymph nodes show. replacement with adipose tissue, but they are otherwise grossly unremarkable. BLOCK SUMMARY: B1-2 deep resection margin at medial aspect of specimen (closest approach of. the tumor to the margin). B3-4. medial resection margin. B5-6. representative sections of the mass, medial to the biopsy cavity. B7. section from fibrous-appearing tissue, lateral to the biopsy cavity. B8. representative sections from upper outer quadrant. B9. representative sections from upper inner quadrant. B10. representative sections from lower outer quadrant. B11. representative sections from lower inner quadrant. B12. nipple. B13. representative portions of skin. B14-1 one lymph node in several parts lower axillary region. B17 one lymph node in three parts, lower axillary region. B18 two lymph nodes, each bisected, lower axillary region; one lymph node is. 1 of 2. inked. B19 four lymph nodes, each single, lower axillary region. B20 one lymph node in several parts, lower axillary region. B21 several questionable lymph nodes, lower axillary region. B22-23 one lymph node node in several parts, upper axillary region. B24 one lymph node in several parts, upper axillary region. B25 two lymph nodes, each bisected, upper axillary region; one lymph node is. inked blue, the other black. B26 four smaller lymph nodes, each single, upper axillary region. B27. highest axillary lymph node (marked with blue ink) and several other. questionable lymph nodes, upper axillary region. INTRA OPERATIVE CONSULTATION: Afl: "Right breast biopsy": Carcinoma. DIAGNOSIS: A. "RIGHT BREAST BIOPSY": INVASIVE LOBULAR CARCINOMA. B. "BREAST TISSUE RIGHT SIDE": INVASIVE LOBULAR CARCINOMA WITH A FOCAL CARCINOMA IN SITU COMPONENT. TUMOR SIZE: APPROXIMATELY 7.0 x 3.5 X 2.5 CM.

expanded version (tokens=1596) : 
 The breast pathology report reveals the following:

- Histological classification: Invasive lobular carcinoma (ILC) with a focal carcinoma in situ component.
- Subtype: Not specified.
- Description of any necrosis: Not mentioned.
- Tumor infiltrating lymphocytes: Not mentioned.
- Histological grade: Not mentioned. ILCs are typically graded on a different scale based on their growth pattern.
- Nuclear grade: Not mentioned. 
- Lymphovascular invasion: Not mentioned.
- Calcification: Not mentioned.
- Receptor status: A representative portion of the mass is submitted for hormone receptor analysis, but the results are not reported in the provided report.
- IHC and any other ancillary testing results: No information given on additional testing.

Expansion of main points:

- Histological classification: The report states that the biopsy and breast tissue on the right side both contain invasive lobular carcinoma (ILC) with a focal carcinoma in situ component. ILC is a type of breast cancer that arises in the milk-producing glands (lobules) and tends to grow in a linear/concentric pattern, making it harder to detect on imaging and often leading to a delay in diagnosis. Carcinoma in situ refers to abnormal cells that have not yet invaded beyond the ducts or lobules where they originated.
- Tumor size and margins: The report notes that the tumor is approximately 7.0 x 3.5 x 2.5 cm in size and

final output (tokens=1758) : 
 Report: A 7.0 x 3.5 x 2.5 cm tumor with invasive lobular carcinoma and a focal carcinoma in situ component was found on the right breast biopsy. The carcinoma extended to within 1 mm of the deep resection margin at the medial aspect of the specimen, while lobular carcinoma in situ was detected in ducts apart from the tumor mass (BLOCK B10). Fourteen axillary lymph nodes were identified, none of which had metastatic carcinoma (0/14). Hormone receptor and additional testing results were not reported.
