GA is a benign epithelial proliferation while stones and cholecystitis secondary to GA may lead to dysplastic changes and cancer.
In studies in which GF rodents were exposed to commensal microbes, increased colonic epithelial proliferation and deepened large bowel crypts were observed [86, 87].

Some of the ducts posses' small comma likes tails of epithelial cells giving them the appearance of tadpole.8Cells of epithelial proliferation had pale eosinophilic cytoplasm and rounded monomorphic nucleus.
In the current understanding, intraductal epithelial proliferations are widely accepted as risk factors for breast carcinoma [7].
The Ki-67 index dropped steadily throughout the 12 months of follow-up, indicative of a decline in breast epithelial proliferation. The decline was greater in soy isoflavone-treated women, although not significantly so.
According to literature, the development of this cyst would be caused by an entrapment of the sinus mucosa in the wound after the surgical procedure followed by an inflammatory process that would stimulate epithelial proliferation. Finally, the expansion of the cyst would be caused by the osmotic pressure difference [3].
Together, the data suggests that paracrine Hedgehog signalling from epithelial to mesenchymal cells promotes stromal niche formation, which in turn affects epithelial proliferation and differentiation.
The defining morphologic feature of these lesions is the presence of arborescent fibrovascular cores that support epithelial proliferation. Papillary lesions of the breast are exclusively intraductal neoplasms, although rarely an invasive carcinoma of the breast may have a predominantly papillary architecture.
Microscopy will reveal cystically dilated duct with papillary epithelial proliferation composed of branching or anastomosing proliferation of single or double layered tall columnar cells with fibrovascular core.
Such findings can be explained by the high epithelial proliferation rate of these tumors, which is responsible for the growth mechanism of these lesions.
