Some studies have found that the average age at diagnosis is in the 60s or early 70s. They are usually indicative of disseminated disease, and the prognosis is poor. Mucinous carcinoma is extremely rare in men.

Even though mucinous carcinoma is an invasive breast cancer, it tends to be a less aggressive type that responds well to treatment. A definitive histopathologic report confirmed metastases to the breast from a mucinous adenocarcinoma of intestinal origin, based on catcinoma 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.

Generally, radical operation should be avoided unless needed for palliation. Abundant mucinous stroma containing epithelial tumor cells with at most mild atypia. As compared with other subtypes of breast cancer, MMCs, in general, present low signal intensity on diffusion-weighted images.

In children, rhabdomyosarcoma is the tumor most commonly associated with breast metastasis 8. Breast neoplasm; Mucinous carcinoma; Mammography; Ultrasonography; Magnetic resonance imaging. Typically, colorectal carcinomas are positive for CK20, whereas this is exceptional cadcinoma primary breast carcinoma 10, Calcification can be rare in pure mucinous types. Normally, mucus lines most of the inner surface of our bodies, such as our digestive tract, lungs, liver, and other vital organs.

Accessed December 31st, At pathological examination, the dominant feature is the presence of mucin within and surrounding cancer carcunoma.

Metastatic caecinoma within the breast.

Articles Cases Courses Quiz. The first cases of breast metastasis from an adenocarcinoma of the colon and rectum were reported by McIntosh in 4. Similarly to morphological findings at mammography and ultrasonography, MMCs, at magnetic resonance imaging, are visualized as ovoid or lobulated masses with predominantly regular contours.

J Surg Oncol ; Fewer than 10 cases have been reported in the literature 1, Table I. Microscopically, it is formed by large mucin lakes surrounded by mucus-producing cancer cells. 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.

Synonyms or Alternate Spellings: There is slight left breast predominance, and the most common site is the upper outer quadrant. The patient was treated with chemotherapy, 5-fluorouracil and irinotecam stopped for intoleranceand capecitabine and Utefos.

At surgery only an incisional biopsy was performed, due to the presence of peritoneal metastases. Mucinous colloid carcinoma Mucinous 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.

The mixed type presents a greater 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. At ultrasound, mucinous carcinomas often display mixed echogenicity with mixed solid and cystic components.

The mucin to cell ratio can vary from lesion to lesion. Click here for patient related inquiries. Soft, pale, grayish blue, gelatin-like and well circumscribed Frequently hemorrhagic. Mixed MCB has a more aggressive behavior.

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

carcinlma 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.

One year later, the patient showed a retroperitoneal mass, about 4 centimetres in size. Generally a radical operation should be avoided unless needed for palliation 2,8, Sonographic appearance of mucinous carcinoma of the breast.

We conclude that metastases to the breast from an adenocarcinoma of the colon are rare. Outcome of pure mucinous breast carcinoma compared to infiltrating ductal carcinoma: Chemotherapy was started using 5-fluorouracil muvinoso associated with folinic acid due to intoler-ance to this component.

J Bras Patol Med Lab. 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.

Six months after surgery carcinona patient was admitted to hospital in a poor health condition due to disseminated disease, and was then referred for supportive care.

These experts are members of the Breastcancer. This case report described a patient with breast metastasis from colon adenocarcinoma treated by simple mastectomy. 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 A mixed MCB tends to be more hypoechoic.
