Fewer than 10 cases have been reported in the literature 1, Table I. Immunohistochemical differentiation between primary adenocarcinomas of the ovary and ovarian metastases of colonic and breast origin. Female, year-old patient with pure MMC.

Crcinoma evaluation of size correlates well with clinical measurements because the metastatic mass does not cause a surrounding desmoplastic reaction in adjacent normal breast 1,2,3,8.

However, the differentiation between pure and mixed types can mucinosk be established after excision and evaluation of the lesion in its whole extent 6,9. Case 3 Case 3. Half of primary tumors of the breast are positive for estrogen and progesterone receptors, and most of them show cytoplasmic stain-ing for GCDFP Histological section of the lesion, identifying mucinous tumor with neoplastic cells involved by moderate amount of extracellular mucin.

Axial MRI STIR image of the described nodule, demonstrating intense hypersignal onT2-weighted sequence with hypointense septa, common findings in mucinous carcinomas. Images hosted on PathOut server: The signal intensity is variable on T1-weighted images and with strong signal similar to that of water or vessels on T2-weighted images Figure 3. On postcontrast images, benign-appearing kinetics with gradual and persistent enhancement is typical and so they can be easily mistaken for a benign lesion.


Metastasis to the breast from colon adenocarcinoma is rare. Pure cases may not need axillary staging Ann Surg Oncol ;9: Given the patient’s previous history of colonic neoplasm, the unusual cytologic findings, and the good health condition of the patient, an incision frozen biopsy was scheduled to rule out metastatic disease to the breast from primary breast carcinoma, in order to choose an adequate surgical procedure.

The presence of mucin results in a low-density and relatively well-defined lobular mass.

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

There is slight left breast predominance, and the most common site is the upper outer quadrant. Female, year-old patient with pure MMC, with typical sonographic findings: Metastatic tumors to the breast from colon adenocarcinoma are very rare.

A year-old woman was diagnosed in with an adenocarcinoma of the right colon, and a right hemicolectomy was performed. Rapid growth is characteristic. In one published report, 11 of 30 mucinous mma carcinomas showed mucinous atypical hyperplasia and in situ ductal carcinoma.

Can MR imaging contribute in characterizing well-circumscribed breast carcinomas?

IDC Type: Mucinous Carcinoma of the Breast

Accessed December 31st, Breast metastases from extramamary malignancies. Even though mucinous carcinoma is an invasive breast cancer, it tends to be a less aggressive type that responds well to treatment. J Clin Pathol ; The present essay is aimed at describing the most characteristic imaging findings of mucinous carcinoma of the breast, with emphasis on the patterns related to better prognosis.

The retroperitoneal mass was treated with radiotherapy. Breast neoplasm; Mucinous carcinoma; Mammography; Ultrasonography; Magnetic resonance imaging.

Typically, they are associated with disseminated metastasic disease and imply a poor prognosis. Contributed by Andrey Bychkov, M. Mucinous Carcinoma of the Breast. The most common primary tumor is a contralateral breast carcinoma, followed by leukemia, melanoma, lymphoma, and ovary, lung and stomach cancer 2,8.

Typically, colorectal carcinomas are positive for CK20, whereas this is exceptional in primary breast carcinoma 10, Acta Path Microbiol Scand ; Homogeneity on sonography is associated with the 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. Highly cellular, loosely cohesive clusters and dissociated cells with intact cytoplasm and nuclei with mild atypia, no oval bare nuclei Also thin walled capillaries, micropapillary pattern of angulated clusters or abortive papillae and carcino,a clusters Acta Cytol ; One year later, the patient showed a retroperitoneal mass, about 4 centimetres in size.


Generally, radical operation should be avoided unless needed for palliation. Carvinoma are two histological carxinoma with different imaging features and prognoses: Generally a radical operation should be avoided unless needed for palliation 2,8, The mucin to cell ratio can vary from lesion to lesion. An exploratory laparotomy was indicated.

Pathology Outlines – Mucinous / colloid carcinoma

This tumor shows a wide age distribution, but with higher incidence in elderly 5. At ultrasound, mucinous carcinomas often display mixed echogenicity with mixed solid and cystic components. A core biopsy specimen usually gives a gelatinous appearance.

The prognosis is poor because they are usually indicative of disseminated disease. The imaging findings may suggest both subtypes of MMCs, pure and mixed ones. Unable to process the form. Log in Sign up.

Mammography showed an ill-defined asymmetric focal dense image with microcalcifications Fig.
