[Local recurrence of ductal carcinoma in situ after conservative breast surgery: mammographic appearance].
OBJECTIVE
To review the mammographic features of local recurrences of DCIS treated conservatively.


METHODS
Thirty-five patients treated conservatively for a DCIS have presented subsequently a local recurrence. Three patients had double metachronous and one a bi-focal recurrence. The mammographic appearances of these 39 recurrences were analyzed retrospectively and compared to initial mammograms.


RESULTS
Median delay to recurrence was of 47 months (interval 8-240 months). Two-thirds of the recurrent lesions were similar to the initial presentation, of which 90% occurred at the lumpectomy site. In 18/ 35 cases (51%), an intra-ductal component was found at histological diagnosis and among these 11/18 (61%) were strictly intra-ductal.


CONCLUSIONS
Local recurrences of DCIS are proteiform. However, the majority of which, occurring at the lumpectomy site were similar to the primary tumor, raising again the hypothesis of incomplete eradication even when the margins were considered free.
