Carcinoma within solitary ductal papilloma of the breast.
BACKGROUND
Solitary ductal papilloma of the breast, traditionally considered a benign disorder, was recently found to have malignant potential, especially when associated with atypical ductal hyperplasia.


METHODS
All patients diagnosed with solitary ductal papilloma at a tertiary medical center from 1994 to 2004 were identified by a database search. Background, clinical and pathological data were collected for those with a carcinoma within the papilloma, and their pathological specimens were revised.


RESULTS
Of the 3849 breast biopsies performed in our medical center during the study period, 77 (2%) yielded a solitary ductal papilloma. In 12 cases (15.6% of all solitary ductal papillomas; 0.3% of all breast biopsies), a carcinoma was found within the papilloma. Ten were diagnosed as carcinoma in situ and 2 as microinvasive carcinoma.


CONCLUSIONS
In the present series, the incidence of carcinoma within solitary ductal papilloma was 15.6%, indicating that solitary ductal papillomas have malignant potential.


CONCLUSIONS
Carcinoma within solitary ductal papilloma of the breast was found in 15.6% of all papillomas. This seems to indicate a malignant potential of papillomas and the need for surgical excision.
