Fewer than 10 cases have been reported in the literature 1, Table I. Immunohistochemical differentiation between primary adenocarcinomas of the ovary and ovarian metastases of colonic and breast origin. Female, year-old patient with pure MMC.

Crcinoma 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.

However, the differentiation between pure and mixed types can mucinosk be established after excision and evaluation of the lesion in its whole extent 6,9. Case 3 Case 3. Half of primary tumors of the breast are positive for estrogen and progesterone receptors, and most of them show cytoplasmic stain-ing for GCDFP Histological section of the lesion, identifying mucinous tumor with neoplastic cells involved by moderate amount of extracellular mucin.

Axial MRI STIR image of the described nodule, demonstrating intense hypersignal onT2-weighted sequence with hypointense septa, common findings in mucinous carcinomas. Images hosted on PathOut server: 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. On postcontrast images, benign-appearing kinetics with gradual and persistent enhancement is typical and so they can be easily mistaken for a benign lesion.

Typically, colorectal carcinomas are positive for CK20, whereas this is exceptional in primary breast carcinoma 10, Acta Path Microbiol Scand ; 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. 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 carcino,a clusters Acta Cytol ; One year later, the patient showed a retroperitoneal mass, about 4 centimetres in size.
