The aim of this study is the clinical, mammograp-hic and ecographic review of patients with mucinous breast cancer diagnosed in our hospital in the past year.

The most common primary tumor is a contralateral breast carcinoma, followed by leukemia, melanoma, lymphoma, and ovary, lung and stomach cancer 2,8.
Radiol Med Torino ; As times the lesion can be isoechoic to breast tissue on ultrasound which can make diagnosis difficult 3. Sonographically, mixed cystic and solid components, distal enhancement, and microlobulated margins are commonly found in mucinous carcinomas. A definitive histopathologic report confirmed metastases to mucinkso breast from a mucinous adenocarcinoma of intestinal origin, based on the presence of ductal in situ carcinoma, a colonic type pattern with “signet ring cells”, and an immunohistochemical study that was negative for estrogen and progesterone receptors, and GCDFP, and positive for CEA cell expression and cytokeratin 20 CK 20 Fig.
Some studies have found that the average age at diagnosis is in the 60s or early 70s.
Thank you for updating your details. A core biopsy specimen usually gives a gelatinous appearance.
The first cases of breast metastasis from an adenocarcinoma of the colon and rectum were reported by McIntosh in 4. In most series, more than 80 percent of patients succumb within one year.
Fewer than 10 cases have been reported in the literature 1, Table I.
In mucinous carcinoma, however, mucin becomes part of the tumor and surrounds the breast cancer cells. Thus, an intense enhancement in the first two minutes after gadolinium injection, or a type 3 curve washout must raise suspicion of mixed type MMC or, an even rarer pure tumor with high cellularity Pure cases may not need axillary staging Ann Surg Oncol ;9: On postcontrast images, benign-appearing kinetics with gradual and persistent enhancement is typical and so they can be easily mistaken for a benign lesion.
Immunohistochemical differentiation between primary adenocarcinomas of the ovary and ovarian metastases of colonic and breast origin.
The mixed type presents a greater amount of neoplastic cells not caarcinoma by mucin, generally in association with a smaller amount of extracellular mucin, which implies intermediate characteristics between the pure type and nonspecific invasive ductal carcinoma NS-IDCfor this reason sometimes referred to as “IDC with mmama differentiation” 6,7.
Typically, colorectal carcinomas are positive for CK20, whereas this is exceptional in primary breast carcinoma 10, Typically there is no spiculation, microcalcification, or thickening of the skin. Homogeneity on sonography is associated with mucinosi pure type of MCB, in which margins are usually well defined, and the tumor is iso-echogenic relative to the fat surrounding the breast tissue on ultrasound.

Outcome of pure xarcinoma breast carcinoma compared to infiltrating ductal carcinoma: Last modified on March 1, at 5: Sparse epithelial component arrow – DCIS by mucin. Breast metastases from extramamary malignancies.
Nuclear atypia is mild. Mastectomy was selected in view of the lesion’s size. Prolonged survival occurs mainly in malignancies for which there is effective chemotherapy 7,8. The retroperitoneal mass was treated with radiotherapy.
Mediolateral, oblique mammographic view demonstrating microlobulated ovoid nodule at the junction of the medial quadrants of the right breast.
Diagnosis and natural history of extramammary tumors metastatic to the breast. Mixed MCB has a more aggressive behavior. Histology from this patient demonstrating mucinous neoplasia with peripheral DCIS foci at left. The carxinoma selected cases of mucinous carcinoma of the breast whose images were available, highlighting the imaging findings suggestive of this subtype of breast cancer, either ,ama mammography, ultrasonography or magnetic resonance imaging.
At mammography, the pure type correlates with circumscribed or micro-lobulated margins, which present a direct relationship with the amount of extracellular mucin 16as demonstrated on Figure 1. Accepted after revision March 7, Mucinous carcinoma of the breast in comparison with invasive ductal carcinoma:
