The imaging findings may suggest both subtypes of MMCs, pure and mixed ones.

IDC Type: Mucinous Carcinoma of the Breast

Support Radiopaedia and see fewer ads. J Clin Pathol ; Microscopically, it is formed by large mucin lakes surrounded by cwrcinoma cancer cells.

They are usually indicative of disseminated disease, and the prognosis is poor. In most series, more than 80 percent of patients succumb within one year. Under a microscope, it looks like the cancer cells are scattered throughout pools of mucus.

Thank you for updating your details. Congeners, prevalence and important pathological associations.


Many types of cancer cells — including most breast cancer cells — produce some mucus. Mixed MCB has a more aggressive behavior. Rapid growth is characteristic.

Some studies have found that the average age at diagnosis is in the 60s or early 70s.

Grimelius staining an agryophilic silver stain denotes neuroendocrine differentiation. New author database being installed, click here for details. Accessed December 31st, Clusters of tumor cells. Fine-needle aspiration cytology suggested a metastatic mucosecretor carcinoma of intestinal origin. Female, year-old patient with pure MMC.

These experts are members of the Breastcancer. Mammographic evaluation can be useful in the differential diagnosis of primary versus secondary breast malignancy.

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.

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.

A simple mastectomy without lymphadenectomy was performed, assuming an extended metastatic disease to cafcinoma breast.

Mucinous carcinoma is extremely rare in men. Female, year-old patient with an ovoid nodule with indistinct and angulated margins, with no noticeable microlobulation, with posterior acoustic enhancement, diagnosed as mixed MMC. 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.


Contributed by Andrey Bychkov, M. Fewer than 10 cases have been reported in the literature 1, Table I. Differences exist between cells of pure and mixed forms Ultrastruct Pathol ; Posterior acoustic enhancement is common. Ulster Med J ; Cellularity as well as the amount of mucin has large variation among mucinous tumors. Can MR imaging contribute in characterizing well-circumscribed breast carcinomas?

Imaging findings in mucin-containing carcinomas of the breast: The case presented in this report had an unusual mammographic appearance, due to the presence of microcalcifications. Mucinous carcinoma is less likely to spread to the lymph nodes than other types of breast cancer.
