Metástasis en mama de carcinoma primario de colon

Only rarely are they multiple or bilateral lesions 8. Many mucinos of cancer cells — including most breast cancer cells — produce mucinoos mucus. Craniocaudal view demonstrating nodule with microlobulated margins in the medial quadrant of the right breast, diagnosed as pure MMC. Log in Sign up. Similarly to morphological findings at mammography and ultrasonography, MMCs, at magnetic resonance imaging, are visualized as ovoid or lobulated masses with predominantly regular contours.

Alveolar and festoon patterns surrounded.

As times the lesion can be isoechoic to breast tissue on ultrasound which can make diagnosis difficult 3. Sign up for our Email Newsletters. Microcalcifications are not caricnoma, and when they occur, rarely represent psammomatous calcifications, most times associated with the presence of peripheral component of DCIS 6,16, Mammographic evaluation can be caricnoma in the differential diagnosis of primary versus secondary breast malignancy.

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. Its clinical incidence varies from 0. Cancers cacinoma to the breast. The progressive enhancement pattern is related to the tumor cellularity, nuclear grading, and amount of extracellular mucin. Mammography showed an ill-defined asymmetric focal dense image with microcalcifications Fig. The retroperitoneal mass was treated with radiotherapy.

Imaging findings in mucin-containing carcinomas of the breast: Such high signal of the MMCs on T2-weighted images shows direct correlation with the degree of extracellular mucin and has high diagnostic sensitivity, although not pathognomonic, since it is also found in other lesions secondary to necrosis, hemorrhage, edema, myxoid matrix or cystic component Diffusion-weighted imaging of mucinous carcinoma of the breast: The prognosis is poor because they are usually indicative of disseminated disease.

Synonyms or Alternate Spellings: The carcinomz intensity is variable on T1-weighted images and with strong signal similar to that of water mucionso vessels on T2-weighted images Figure 3. One year later, the patient showed a carcinomw mass, about 4 centimetres in size. The classic mammographic finding is a rounded, well-circumscribed mass. Most metastases present as palpable breast masses that are usually mobile, but occasionally adherent to the skin 9.

Mixed mucinous tumors may exhibit lower ADC values, similarly to other breast cancer subtypes. Rapid growth is characteristic.

Histopathology Breast – Colloid carcinoma. Pure and mixed mucinous carcinoma of the breast: Even though mucinous carcinoma is an invasive breast cancer, it tends to be a less aggressive type that responds well to treatment. A simple mastectomy without lymphadenectomy was performed, assuming an extended metastatic disease to the breast. Imaging findings and accuracy of core needle biopsy in mucinous carcinoma of the breast.

Ultrasonography has higher sensitivity than mammography in the detection of MMCs 16, The first cases of breast metastasis from an adenocarcinoma of the colon and rectum were reported by McIntosh in 4.

IDC Type: Mucinous Carcinoma of the Breast

Microscopically, it is formed by large mucin kama surrounded by mucus-producing cancer cells. Axial MRI STIR image of the described nodule, demonstrating intense hypersignal onT2-weighted sequence with hypointense septa, common findings in mucinous carcinomas.

Can MR imaging contribute in characterizing well-circumscribed breast carcinomas? A fine-needle aspiration cytology was confirmatory of colon adenocarcinoma recurrence.

Fine-needle aspiration cytology suggested a metastatic mucosecretor carcinoma of intestinal origin. The case presented in this report had an unusual mammographic appearance, due to the presence of microcalcifications.
