What is focal tubal metaplasia?

Focal tubal metaplasia is a condition characterized by the abnormal transformation of epithelial cells in the fallopian tubes, often observed in the context of endometriOSis or pelvic inflammatory disease. This metaplastic change can result in the replacement of normal tubal epithelium with different cell types, typically as an adaptive response to injury or inflammation. While it is generally considered a benign finding, focal tubal metaplasia may be associated with various gynecological conditions and is sometimes noted in histopathological examinations. Further investigation may be necessary to determine its clinical significance in individual cases.
