title: Papillomatosis and breast cancer: a case report and a review of the literature.
abstract: Papillomatosis is a relatively common (22%) benign microscopic lesion in the breast and rarely seen in women less than 30 years old. It is a papillary proliferation of the ductal epithelium which partly fills up smaller ducts and to degree distends them. The histological classification of this entity is controversial because similar or identical lesions have been classified using different terms such as epitheliosis and epithelial hyperplasia, and interpretation of published series has been difficult due to imprecise definition of this term. Clinical, radiological and histological patterns of this entity are often sufficient to raise concern as to possible malignancy. Moderate or florid hyperplasia without atypia is considered to carry slight (1,5-2 times) increase in risk of later developing cancer, while in the atypical hyperplasia the risk is four to five times that of the general population. The authors describe a case of papillonlatosis recentely observed in a 67 years old female patient and, confirmed the importance to establish an accurate preoperative diagnosis. It is important that the surgeon works with the pathologist to produce clear descriptive report of epithelial changes from normal through hyperplasia to atypias in order to establish a precise surgical indication.
