Non-mass versus mass-like ultrasound patterns in ductal carcinoma in situ: is there an association with high-risk histology?

To review the ultrasound (US) patterns of pure ductal carcinoma in situ (DCIS) using a non-mass-like (NML) versus mass-like (ML) classification and to investigate histopathological associations.

We present a rare case of Paget disease of the nipple without the typical characteristics, detected by simple nipple scraping technique. A 62-year-old woman presented with a small fissure on the left nipple with scant clear nippledischarge. There were no other changes to the nipple-areola complex. The mammography and ultrasound were unremarkable. However, nipplescraping provided the immediate cytological diagnosis of Paget disease. Breast MRI with core biopsy showed high grade ductal carcinoma in situwith suggestion of microinvasion, confirmed histologically after mastectomy. Nipple scraping is a simple and inexpensive tec...

AbstractIntroductionBreast cancer is the most commonly diagnosed female cancer. Diagnosis in younger women (under 35  years) is different to their older counterparts, and mammography is not considered as sensitive in this cohort. Consequentially, younger patients may present later with more advanced disease.MethodsThis is a retrospective analysis of a prospectively updated database containing consecutive patients who presented to the symptomatic breast unit of Galway University Hospital between 2009 and 2015. Patient clinicopathologic factors, clinical examination features, diagnostic radiological modalities and Bi-RA...

ConclusionAfter a percutaneous biopsy diagnosis of ADH, malignancy can be ruled out in most of the cases, if no suspicious enhancement is present in the biopsy area at DCE-MRI. Breast DCE-MRI may be used to avoid surgery in more than half of the patients with final benign diagnosis.Key Points• Breast DCE-MRI can safely rule out malignancy if no suspicious enhancement is present in the biopsy area after a percutaneous biopsy diagnosis of ADH.• All cases of upgrade to high-grade DCIS and invasive cancers can be identified at breast DCE-MRI after a percutaneous biopsy diagnosis of ADH.• Breast DCE-MRI may be us...

AbstractPurpose of ReviewWe aim to review the appearance of ductal carcinoma in situ (DCIS) across the spectrum of imaging modalities used in common clinical practice.Recent FindingsChanges in technology and clinical breast cancer screening patterns have impacted the imaging evaluation of DCIS. DCIS classically presents as asymptomatic calcifications in women undergoing screening mammography. The replacement of traditional 2D mammography with digital breast tomosynthesis has changed the typical appearance of screen-detected DCIS. Ultrasound is traditionally utilized to detect DCIS in women with clinical symptoms, but effor...

ConclusionDCIS cases with duct abnormalities on ultrasound were investigated in this study. The important characteristics were as follows: (1) the distribution of ductal dilatation was focal or segmental, (2) solid parts were present in the dilated ducts, (3) the distribution of internal echoes was continuous or multiple, (4) the shape of solid echoes was broad-based and/or irregular, and (5) internal echoes were sometimes accompanied by echogenic foci. Accurate evaluation of these findings may be useful for diagnosing DCIS. Although the duct abnormalities are included in “ASSOCIATED FEATURES” in ACR BI-RADS AT...

CONCLUSIONS: In the absence of clinical findings during physical breast examination, the addition of breast ultrasonography does not provide additional information to supplement the physical examination in self-referred women under age 40 who do not have any major risk factors for developing breast cancer.

ConclusionsMRI is the best predictor of tumor size in breast cancer. Histologic type and tumor size are key parameters when estimating tumor size and should be taken into account when planning surgery. Patient age does not interfere with the interpretation of imaging tests.ResumenIntroducciónEl objetivo de este estudio fue evaluar qué prueba de imagen de las empleadas para medir el tamaño del cáncer de mama primario preoperatorio (mamografía, ecografía o resonancia magnética (RM)) se correlacionó mejor con el tamaño del tumor en la pieza quirúrgica posto...

The purpose of this study was to determine whether disease recurrence and intrinsic characteristics of ductal carcinoma in situ (DCIS) are associated with the imaging method of detection in asymptomatic women. This multicenter, retrospective study included 844 women treated for asymptomatic DCIS who had pre-operative mammography and breast ultrasonography (US) studies available. Of the 844 women, 25 (3.0%) developed recurrences. Patients in the US group had significantly lower 5- and 10-y recurrence-free survival (RFS) rates compared with patients in the mammography group (p  = 0.011).
