Ductal carcinoma in situ

Case contributed by Dr Valerio Giacalone


The patient undergoes regular mammography screening.

Patient Data

Age: 45 years
Gender: Female

A group of dysmorphic, non-specific calcifications, assessed as suspicious, probably malignant, can be seen at the upper outer quadrant of the right breast. On microfocus, the calcifications are suspicious for a malignant lesion of the "crushed stone" type. 

Case Discussion

It was decided with the patient to perform a stereotactic biopsy.
The histological results showed foci of high-grade ductal carcinoma in situ (consistent P63). No evidence of invasive neoplasia in the material under examination.
