Fig. 5: About one-third of core needle biopsies showed benign lesions that may or may not correlate with architectural distortion.

A Some biopsies showed areas of dense fibrotic tissue. B A less common finding was fibroadenomatoid change. C A single case showed fragments of a papilloma. The excision also showed a large papilloma. D The remaining cases consisted of a variety of benign changes that did not fit into any of the other categories (e.g., micro-cysts without rupture, micro-papillomas, columnar cell change, usual ductal hyperplasia).
