Intracystic (encysted) papillary carcinoma of breast

Discussion:

In the operating theater the lesion was partially aspirated (hemorrhagic fluid) to prevent an accidental rupture and then it was completely removed under local anesthesia.

Final pathological  diagnosis: intracystic papillary carcinoma, with  positive estrogen and progesterone receptors , negative HER-2-neu receptor and a Ki-67 index of 8%.

The intracystic (encysted) papillary carcinoma is a rare carcinoma with incidence of 0.5% to 1% of all breast cancers, usually seen in elderly women.

It is considered as an in situ or minimally invasive neoplasm.
