Fibroadenoma of the breast is a benign tumor composed of a biplastic proliferation of both stromal and epithelial components. [ 12 ] [ 13 ] This biplasia can be arranged in two growth patterns: pericanalicular (stromal proliferation around epithelial structures) and intracanalicular (stromal proliferation compressing the epithelial structures ...
For comparison, this is about 15 years older than the typical age of patients with a fibroadenoma, a common differential diagnosis in patients with a suspected phyllodes tumors. [26] Younger women have a higher chance of having a benign phyllodes tumor, while older women are more likely to have higher-grade tumors. [23]
Weathers and Callihan examined over 2,000 fibrous hyperplasias and 108 of them met their criteria for giant-cell fibroma. [8] In 1982 Housten performed a study of 464 giant-cell fibromas at the Indiana University School of Dentistry and agreed that the giant-cell fibroma was truly a distinctive lesion.
