Female, year-old patient with anatomopathological diagnosis of pure MMC.

The signal intensity is variable on T1-weighted images and with strong signal similar to that of water muciniso vessels on T2-weighted images Figure 3. Mucinous carcinoma of the breast — sometimes called colloid carcinoma — is a rare form of invasive ductal carcinoma cancer that begins in the milk duct and spreads beyond it into nearby healthy tissue.

Mastectomy was selected in view of the lesion’s size. Metastatic tumors to the breast from colon adenocarcinoma are very rare.

Solitary breast metastasis from carcinoma of colon. They are usually indicative of disseminated disease, and the prognosis is poor. The greater the amount of mucin, the better the prognosis is mxma. Many types of cancer cells — including most breast cancer cells — produce some mucus.


IDC Type: Mucinous Carcinoma of the Breast

Overall the tendency to metastasize is less than for other types of cancer e. Acta Path Microbiol Scand ; Histological diagnosis The diagnosis of mucinous neoplasm may be suspected at fine-needle aspiration biopsy FNABalthough with low accuracy in the differentiation between benign mucoceles and malignant mucinous lesions MMC.

Mucinous colloid carcinoma Czrcinoma colloid carcinoma of breast Colloid breast cancer Mucinous breast cancer Colloid carcinoma of the breast Mucinous breast carcinoma Colloid breast carcinoma Gelatinous carcinoma of the breast. Simple mastectomy is sometimes required when the tumor is bulky, deep-seated or painful.

Metástasis en mama de carcinoma primario de colon

The present mucinsoo is aimed at describing the most characteristic imaging findings of mucinous carcinoma of the breast, with emphasis on the patterns related to better prognosis. Metastasis to the breast from an extramammary malignancy is a rare finding. Ulster Med J ; Histological section at microscopy identifying mucinous tumor with a remarkable amount of mucin and little cellularity.

As times the lesion can be isoechoic to breast tissue mucinoo ultrasound which can make diagnosis difficult 3.

Breast neoplasm; Mucinous carcinoma; Mammography; Ultrasonography; Magnetic resonance imaging. A definitive histopathologic report confirmed metastases to the 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.

Craniocaudal view demonstrating nodule with microlobulated margins in the medial quadrant of the right breast, diagnosed as pure MMC.

Since then, fewer than 10 cases have been reported in the literature 1, There are two histological presentations with different imaging features and prognoses: Mammography and ultrasonography allow a satisfactory evaluation of the lesion’s morphology, but magnetic resonance imaging, besides providing data on morphology, also provides clues about tissue composition and along with the enhancement pattern after administration of gadolinium-based contrast medium, contribute to a better characterization of the lesion and to improve diagnostic accuracy.


As compared with other subtypes of breast cancer, MMCs, in general, present low signal intensity on diffusion-weighted images. Color mapping of wash-in B and kinetic curve C showing slight enhancement at the early phase with progressive enhancement pattern.

The mucin to cell ratio can vary from lesion to lesion.

Mucinous carcinoma of the breast: a case report and review of the literature.

The mixed type presents a greater amount of carcinomma cells not involved 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 mucinous differentiation” 6,7. At ultrasound, mucinous carcinomas often display mixed echogenicity with mixed solid and cystic components.

Sometimes mucinous breast carcinomas show a ductal infiltrating solid component, the presence of “signet ring cells” being uncommon. Infiltrating ductal carcnioma with focal mucinous change Invasive micropapillary carcinoma: An exploratory laparotomy was indicated.
