Generally, excision biopsy is the appropriate treatment and provides adequate local control. Generally a radical operation should be avoided unless needed for palliation 2,8, Acta Path Microbiol Scand ; Since then, fewer than 10 cases have been reported in the literature carcinooma, Typically, a MMC presents as carcinomma ovoid or round nodule with circumscribed margins.

In Januarya painless 4-centimetre breast mass was found in the upper outer quadrant of the left breast. Only rarely are they multiple or bilateral lesions 8. J Surg Oncol ; 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. As times the lesion can be isoechoic to breast tissue on ultrasound which can make diagnosis difficult 3.
The mixed type presents more indistinct or spiculated contours secondary to a higher degree of fibrosis and peripheral desmoplasia, similarly to a NS-IDC.
Female, year-old patient with pure MMC. A core biopsy specimen usually gives a gelatinous appearance.

A mixed MCB tends to be more hypoechoic. In addittion, the presence of intermediate signal on T2-weighted czrcinoma suggests the mixed type of MMC. Infiltrating ductal carcinoma with focal mucinous change Invasive micropapillary carcinoma: On dynamic contrast-enhanced sequences, any enhancement morphology may occur, however, peripheral, ring-shaped or heterogeneous enhancement are more characteristic, and progressive along time Figure 3.
Female, year-old patient with anatomopathological diagnosis of pure MMC. Pure cases may not need axillary staging Ann Surg Oncol ;9: Homogeneity on sonography is associated with the pure type of MCB, in mucinowo margins are usually well defined, and the tumor is iso-echogenic relative to the fat surrounding the breast tissue on ultrasound. On postcontrast images, benign-appearing kinetics with gradual and persistent enhancement is typical and so they can be easily mistaken for a benign lesion.
One year later, the patient showed a retroperitoneal mass, about 4 centimetres in size. 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.
Metástasis en mama de carcinoma primario de colon
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 ball-like clusters Acta Cytol ; Half of primary tumors of the breast are positive for estrogen and progesterone receptors, and most of them show cytoplasmic stain-ing for GCDFP In children, rhabdomyosarcoma is the tumor most commonly associated with breast metastasis 8.
Clusters of tumor cells. Mucinous carcinoma is extremely rare in men. Alveolar and festoon patterns surrounded. In one published report, 11 of 30 mucinous breast carcinomas showed mucinous atypical hyperplasia and in situ ductal carcinoma. Was this article helpful? In most series, more than 80 percent of patients succumb within one year.
A fine-needle aspiration cytology was confirmatory of colon adenocarcinoma recurrence.
Mucinous carcinoma of the breast: a case report and review of the literature.
Mixed mucinous tumors may exhibit lower ADC values, similarly to other breast cancer subtypes. In mucinous carcinoma, however, ccarcinoma becomes part of the tumor and surrounds the breast cancer cells.
Excision biopsy is usually appropriate and provides adequate local control, but sometimes simple mastectomy is necessary. We conclude that metastases to the breast from an adenocarcinoma of the colon are rare. The mucinosi presented in this report had an unusual mammographic appearance, due to the presence of microcalcifications.
