In mucinous carcinoma, however, mucin becomes part of the tumor and surrounds the breast cancer cells.

The cacinoma of mucin results in a low-density and relatively well-defined lobular mass. Overall the tendency to metastasize is less than for other carcionma of cancer e. Histology from this patient demonstrating mucinous neoplasia with peripheral DCIS foci at left. Diagnosis and natural history of extramammary tumors metastatic to the breast.

The prognosis is poor because they are usually indicative of disseminated disease. Pure type shows indolent growth, while the mixed type presents variable biological behavior, sometimes similar to NS-IDCs Mammographic 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.

In most series, more than 80 percent of patients succumb within one year. At ultrasound, mucinous carcinomas often display mixed echogenicity with mixed solid and cystic components. Diffusion-weighted imaging of mucinous carcinoma of the breast: Images hosted on PathOut server: J Surg Oncol ; Excision biopsy is usually appropriate and provides adequate local control, but sometimes simple mastectomy is necessary.

Most metastases present as palpable breast masses that are usually mobile, but occasionally adherent to the skin 9. 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 Under a microscope, it looks like the cancer cells are scattered throughout pools of mucus.


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 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.

An exploratory laparotomy was indicated. Within metastatic disease to the breast, colon cancer metastases are rare. A fine-needle aspiration cytology was confirmatory of colon adenocarcinoma recurrence. 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.

Thank you for updating your details. Semir Vranic, University of Sarajevo Bosnia. Metastasis to the breast from an extramammary malignancy is a rare finding. The most common primary tumor is a contralateral breast carcinoma, followed by leukemia, melanoma, lymphoma, and ovary, lung and stomach cancer 2,8. Mucinous carcinoma is less likely to spread to the lymph nodes than other types of breast cancer. In Januarya painless 4-centimetre breast mass was found in the upper outer quadrant of the left breast.

Metastatic tumors to the breast from colon adenocarcinoma are very rare. The mixed type presents a mucinowo amount of neoplastic 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.

The greater the amount of mucin, the better the prognosis is 6. Breast metastases from extramamary malignancies. In addittion, the presence of intermediate signal on T2-weighted images suggests the mixed type of MMC. 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 carciinoma medium, contribute to a better characterization of the lesion and to improve diagnostic accuracy.

Mixed MCB has a more aggressive behavior. Only rarely are they multiple or bilateral lesions mucjnoso. Calcification can be rare in pure mucinous types. 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.

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

Metastatic carcinoma within the breast. At surgery only an incisional biopsy was performed, due to the presence of peritoneal metastases. Mucinous carcinoma [title] breast.

Similarly to morphological findings at mammography and ultrasonography, MMCs, at magnetic resonance imaging, are visualized as ovoid or lobulated masses with predominantly regular contours. Comparison between stadistical and intuitive approach. Synonyms or Mucinozo Spellings: Generally, excision biopsy is the appropriate treatment and provides adequate local control.

The patient was treated with chemotherapy, 5-fluorouracil and irinotecam stopped for intoleranceand capecitabine and Utefos.
