Florid cystic endosalpingiosis, masquerading as malignancy in a young patient: a brief review

Uterine Serous Cystadenoma or Endosalpingiosis?: A Case Report with a Review of Literature

Endosalpingiosis is a nonneoplastic lesion defined by the presence of tubal epithelium at ectopic sites such as the peritoneum, bladder, appendix, and even uterus. They may be asymptomatic and detected incidentally on ultrasonography. However, cystic endosalpingiosis is also known to be a mimicker of ovarian neoplasms. It is crucial for both the clinician and the pathologist to be aware of this benign lesion so that overdiagnosis and overtreatment can be avoided. We report a case of endosalpingiosis of the uterine serosa in a 45-year-old woman which was misdiagnosed as an adnexal cyst on radiological investigations.

Intraoperative Appearance of Endosalpingiosis: A Single-Center Experience of Laparoscopic Findings and Systematic Review of Literature

Background: Endosalpingiosis is assumed to be the second most common benign peritoneal pathology after endometriosis in women. Although recent studies indicate a significant association with gynecologic malignancies, many underlying principles remain unclear. This work aimed to systematically describe the intraoperative appearance of endosalpingiosis. Methods: Data and intraoperative videos of patients with histologically verified endosalpingiosis were retrospectively reviewed. The main outcome measures were macroscopic phenotype and anatomical distribution. Additionally, a systematic review searching PubMed (Medline) and Embase was conducted. Results: In the study population (n = 77, mean age 40.2 years (SD 16.4)), the mean size of lesions was 3.6 mm and the main visual pattern was vesicular (62%). The most frequent localization was the sacrouterine ligaments (24.7%). In the systematic review population (n = 1174 (210 included studies overall), mean age 45.7 years (SD 14.4)), there were 99 patients in 90 different studies with adequate data to assess the appearance of the lesions. The mean size of the lesions was 48.5 mm, mainly with a cystic visual pattern (49.5%). The majority of the lesions affected the ovaries (23.2%), fallopian tubes (20.4%), or lymph nodes (18.5%). Comparing this study to the literature population, the main differences concerned the size (p < 0.001) and main visual patterns (p < 0.001) of lesions. Conclusions: The usual intraoperative findings of endosalpingiosis appeared less impressive than described in the literature. In our study population, lesions of a few millimeters in size with a vesicular appearance were mostly seen, most frequently in the sacrouterine ligament area. Intraoperative recognition by the gynecologic surgeon and histologic diagnosis should play an important role in further understanding this entity, scientifically and clinically.

Cystic Uterine Endosalpingiosis in a Patient with Carcinoma Endometrium

Endosalpingiosis is a benign condition characterized by the presence of tubal-type epithelial cells outside the Fallopian tube. It may rarely involve the uterus and present as a cystic or tumor-like mass. We report an unusual case of cystic uterine endosalpingiosis in a postmenopausal female with carcinoma endometrium. Preoperative and intraoperative diagnosis of this condition is challenging. Awareness about this condition in clinicians may help in preventing misdiagnosis and overtreatment.

A Rare Mimic of Malignancy: Papillary Endosalpingiosis

Endosalpingiosis is the presence of ectopic Müllerian-type epithelium resembling Fallopian tube epithelium. It usually appears as small glandular inclusions in various peritoneal sites or lymph nodes. Rarely, it is papillary in configuration, and lack of familiarity with this entity could lead to overinterpretation as a malignancy. We recently encountered a case of papillary endosalpingiosis found incidentally at laparotomy for ectopic pregnancy. Awareness of this entity is important, as it may be a diagnostic challenge.

[Ectopic tissue of the female genital tract]

Ectopias of female genital tissues are a common event in routine pathology. Mostly they derive from paramesonephric tissues displaced during embryonal development or later. However, gonadal-, mesonephric-, or mesothelial-derived tissues may also appear in unusual localizations in and outside the female genital tract. They may be the source of benign and malignant tumors or tumor-like lesions. This review aims to provide an overview of possible tissue ectopias and to improve the developmental understanding of tumorous diseases of the female genital tract. Ectopias of primarily extragenital tissues in the female genital tract are also reviewed.
