56. Fibroadenoma of the breast
Organ: Breast
Description:
We can see a well-circumscribed, encapsulated tumor with an expansile border. The tumor doesn’t invade the surrounding parenchyme and fat tissue.
Diagnosis: Fibroadenoma of the breast
Causes:
- Unknown
- Most likely an increase in oestrogen is involved
Theory:
The tumor contains both proliferating ductal elements (adenoma) and loose fibrous tissue (fibroma).
In patho 1 it is only important to describe the tumor with the terms: encapsulated, expansile border and well-circumscribed. This is a benign tumor.
This type of tumor stands in contrast to breast carcinoma, and these two topics should be learned together and compared.
