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
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.
