Endosalpingiosis mimicking recurrent ovarian carcinoma

摘要

Endosalpingiosis is defined as the presence of glandular nests covered by tubal epithelium in the peritoneum or on the serous surface of the uterus and ovaries [1]. It is a rare entity, which normally appears in women of reproductive age, with an average age of presentation between 30 and 50 years [2-4], It often appears alone, but it is not unusual to find endosalpingiosis associated with endometriosis or endocervicosis [5]. It has been theorized that it may be involved in the pathogenesis of ovarian tumors, although not enough evidence has been found to confirm this hypothesis [6]. The diagnosis of endosalpingiosis is made histologically. It usually consists of a layer of simple columnar epithelium formed by ciliated cells, non-ciliated secretory cells and peg cells. In addition, it can form papillae, show psammoma bodies and be surrounded by chronic inflammatory cells [3]. Sometimes it can mimic neoplasms and peritoneal tuberculosis on a macroscopic level, making a difficult differential diagnosis [7,8].
