Tumor-Like Lesions and Endometriosis, Pathology of the Peritoneum

Endosalpingiosis Definition Ectopic fallopian tube epithelium. Clinical Features - Incidence 13%. Frequently occurs in association with ovarian serous borderline tumors and low-grade serous carcinoma. - Age Wide age range, but more commonly found in women of reproductive age. - Sex Female. - Site Peritoneum, pelvic soft tissue, and lymph nodes. - Treatment Usually an incidental finding at surgery for other indications. - Outcome This is a benign lesion. Macroscopy Not typically grossly appreciable. When presenting as florid cystic endosalpingiosis, it rarely forms a mass lesion. Microscopy Simple glands lined by a single layer of serous-type epithelium containing peg cells and ciliated cells. Intraglandular stromal projections forming simple papillae may be present (Fig. 1).
