Breast core biopsy with 8 cores. There are multiple breast lesions. Try you diagnosis one by one.
Lesion 1 20x and 400x
Thank every one for giving dx for this case.
1. Lobular carcinoma in situ (immunostains support the diagnosis.
2 Micropapillary apocine change or metaplasia. Uniform nuclei, micropapillary growth pattern. It is completely benign. Papilary or micropapillary apoccrin changes are very common. It is part of fibrocystic changes (FCC). Generally I just call FCC and d not mention the apocrine cmetaplasia. If they are ductal epithelial cells without apocrine change. The lesions with the same cytomorphology need to be diagnosed as ADH or low grade DCIS with micropapillary pattern. This is why I pasted this photo here.
3. Columinar cell change (CCC): Single layer of columnar cells lining the dilated acini with secretion. I do not see atypia even though some nuclei are round. It is not enough to call flat epithelial atypia even though the lining cells are not classic columinar cells.
4. Intraductal papilloma.
6. Radial scar. It is not a wrong diagnosis if you call sclerosing diangosis. They are in the same categry of the lesions.
In our hospital if diagnosis is radial scar in breast core biopsy, breast surgeons will do an excisional biopsy. So we are cautious for this diagnosis if no other severe lesions in the breast core. I think there were some studies which indicated tha radial scars increase the risk of cancers. But I am really not sure it is true. So if it is not a typical radial scar, I generally will not call it. I may call sclerosing adenosis. For this case I think it is reasonable to call radial scar.
OK, I have to do sth now. We will discuss the photo 5 and 7.
You can write your oppinion about the 5 lesions if you do not agree with me.
I f you agree, we can concentrate on the other two lesions now.
Thanks,

Quickly review all of your interpretation. Most of them are reasonable. In this topic I will concentrate for the interpretaion of FEA, columnar cell change. If you are interested you can review the text book or related articles for some photos first. Then we can have some discussion together. Dr. Stuart, J. Schnitt from Beth Israel Deaconess Medical Center, Harward Medical School, Boston, MA did a lot of study in this area. In fact he raised some terms. Frequently speaking, I am often confused by the diagnosis of FEA in my clinical practice.
Hope more people share the diagnosis about my first 7 lesions from the same patient.
Thanks,

1. Lobular carcinoma in situ.
2.atypical duct hyperplasia, papillary variant.
3.dilated duct.
4. papilloma.
5.columnar cell change
6.sclerosing adenosis
7.columnar cell lesions including columnar cell change, columnar cell hyperplasia,flat epithelial atypia(atypical duct hyperplasia?)
以下是引用luolili在2009-2-18 14:22:00的发言:
此病变有以下特征: 1 导管上皮增生,伴有轻-中度非典型增生 2 导管上皮乳头状增生,伴大汗腺化生 3 导管囊性扩张伴分泌物潴留 4 导管内乳头状瘤 5 ?是导管良性病变 6 纤维囊性乳腺病 7 腺病,导管上皮增生,伴中度非典型增生。 新手上路,望各位老师多多指教。 |
Breast pathology is complicated. We as pathologists need to recognize the cancers and all other borderline or benign lesions. There are several lesions in this breast core specimen. Please make your dx based on above orders, lesion 1, 2, 3,....
Thanks,
