Triple Negative Invasive Ductal
Carcinoma Arising in a Breast Cyst
Sarah Himmelstein, MD; Emily Penman, MD FIGURE 1
Intracystic breast cancer is uncommon, comprising less than 1 percent of all malignant breast cancers. Classically, intracystic cancer is of papillary histologic subtype and is estrogen receptor positive.
We report on the case of a patient who was found to have invasive ductal carcinoma of
a cyst wall, which was found
to be estrogen receptor, progesterone receptor and Her-2 negative. This presented a unique management challenge as there have been no previously reported cases with discussion of treatment in the literature. The subsequent multidisciplinary approach to this patient’s care is discussed.

CASE PRESENTATION
The patient is a 70-year-old Caucasian female who initially presented to her primary care physician with a mass
in the right breast. She had a complex past medical history including a ruptured intracranial aneurysm in 1980 with resultant left hemiparesis and chronic headaches. Her past surgical history included bilateral reduction mammoplasty as well as a biopsy of her right breast in 2011 that proved
to be fat necrosis. Physical exam was
overlying skin that measured 6 cm at the 1 o’clock position, 3 cm from the nipple.
