View source for 42. Mucinous carcinoma

[[File:Mucinous carcinoma - overview.png|thumb|Overview]]''This slide is no longer part of the curriculum as of spring 2020, so you shouldn’t have to learn it.''

'''Staining''': HE

'''Organ''': Breast

'''Description''':

The top of the slide shows normal breast tissue. The tumor is obvious.

The tumor cells form clusters that are “floating in a sea of mucin”. These tumor cells have lost their orientation and therefore secrete mucin outwards instead of inwards (into an acinus)

'''Diagnosis''': Mucinous carcinoma

'''Risk factors:'''

* Usually older women
* Probably same as for other breast cancers[[File:Mucinous carcinoma - mucus.jpg|thumb|The arrows show the direction in which the tumor cells are secreting mucin]]

'''Theory''':

Mucinous carcinoma is a rare type of breast carcinoma, accounting for less than 3% of cases. It has a better prognosis than invasive ductal carcinoma.
