ENDOSALPINGIOSIS OF BLADDER

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.

Müllerianosis of the Urinary Bladder: A Rare Condition Which Mimics Neoplasia

Müllerianosis of the urinary bladder is an extremely rare, benign condition defined by the presence of at least two of the three müllerian-derived components (endosalpinx, endometrium, and endocervix) in the lamina propria and muscularis propria of the urinary bladder. It frequently mimics neoplastic condition, either malignant or benign. Here, we present a case of cystic müllerianosis of urinary bladder, which was clinically thought to be a urinary bladder neoplasm.

Endosalpingiosis of urinary bladder: report on a rare entity

A case of endosalpingiosis of the urinary bladder is presented with imaging features on sonography and CT. Patient presented with right flank pain, dysuria and haematuria. She had h/o right renal calculus and abdominal hysterectomy 15 years ago. On sonography a polypoidal filling defect was noted and possibility of a bladder neoplasia was suggested. On cystoscopy and removal of the lesion and subsequent histo-pathological analysis revealed the diagnosis of endosalphingiosis. This report emphasizes the need for evaluation of all clinical inputs while considering the differential diagnosis of an intraluminal bladder lesion. Imaging appearance and aetio-pathology of the rare intra vesical lesion is highlighted.

Müllerianosis, Endocervicosis, and Endosalpingiosis of the Urinary Tract: A Literature Review

INTRODUCTION AND HYPOTHESIS

We reviewed reported cases of endocervicosis, endosalpingiosis, and müllerianosis of the bladder or ureters in women in order to highlight these conditions as distinct from endometriosis or adenomyosis.

METHODS

Medline and Scopus searches of all cases published till the October 1, 2017. All retrieved references were searched manually to identify relevant articles.

RESULTS

Twenty-six articles reported endocervicosis. These included 37 cases described by the authors as endocervicosis of the bladder. We identified 7 case reports of bladder endosalpingiosis. There were 26 publications including 27 cases of müllerianosis of the bladder and 3 cases affecting the lower ureter. Literature descriptions are limited but available accounts do not point to features that uniquely distinguished these conditions. Affected women tended to be older, and in many cases, there was a possible relation to past surgery and particularly to hysterectomy and caesarean sections. Many cases were reported in postmenopausal women. Local excision was sufficient in most cases.

CONCLUSION

The etiology of these conditions remains speculative, but case reports raise a possible link to pelvic surgery. There is a need for more detailed accounts of these lesions, which should be considered in the differential diagnosis of pre- and postmenopausal women with pelvic pain, dyspareunia, lower abdominal pain or discomfort, dysuria, frequency, or hematuria.

Vaginal Endosalpingiosis Case Report: A Rare Entity Presenting as Intermenstrual Bleeding

Endosalpingiosis is a benign and rare entity whose pathophysiology remains unknown. It has been described in pelvic organs, the abdomen, or axillar lymph nodes. Its underrecognition has occasionally led to its misinterpretation for an adenocarcinoma. This case reports the treatment and follow-up of vaginal endosalpingiosis, presenting as a vaginal polyp in a premenopausal women with intermenstrual bleeding. To our knowledge this is the first reported case of vaginal endosalpingiosis and the second mucosal localization after bladder endosalpingiosis.

Mullerianosis of the urinary bladder: report of a case with diagnosis suggested in urine cytology and review of literature

Mullerianosis of the urinary bladder is a rare entity characterized by the presence of an admixture of at least two types of mullerian tissue in the muscularis propria of the bladder. We report a case of mullerianosis of the urinary bladder in a 28-year-old nulliparous woman with no history of pelvic surgery or endometriosis, and the diagnosis of mullerianosis was suggested initially in urine cytopathology report. In this study, previously reported cases of mullerianosis of urinary bladder are reviewed, and differential diagnosis of endometrial-like cells in the urine has been discussed. Fewer than 20 cases of mullerianosis of the urinary bladder have been reported in the literature, and only one of these cases had cytological description in a urine specimen. Most of patients were of reproductive age ranging from 28 to 53 years and had no previous history of pelvic surgery or Cesarean section. The clinical presentations frequently were abdominal/pelvic pain and dysuria/hematuria, which may or may not be associated with menstruation. Radiologic study revealed polypoid, mass-like lesion ranging from 1 to 4.5 cm in size, predominantly involving the dome or posterior wall of the bladder. Histological sections showed two or more of the three related benign mullerian glandular epithelial proliferations-endometriosis, endosalpingiosis, and endocervicosis. Most of the patients have good prognosis with medical management.

Umbilical endosalpingiosis: a case report

Introduction

Endosalpingiosis describes the ectopic growth of Fallopian tube epithelium. Pathology confirms the presence of a tube-like epithelium containing three types of cells: ciliated, columnar cells; non-ciliated, columnar secretory mucous cells; and intercalary cells.

We report the case of a woman with umbilical endosalpingiosis and examine the nature and characteristics of cutaneous endosalpingiosis by reviewing and combining the other four cases existing in the international literature.

Case presentation

A 50-year-old Caucasian, Greek woman presented with a pale brown nodule in her umbilicus. The nodule was asymptomatic, with no cyclical discomfort or variation in size. Her personal medical, surgical and gynecologic history was uneventful. An excision within healthy margins was performed under local anesthesia. A cystic formation measuring 2.7×1.7×1 cm was removed. Histological examination confirmed umbilical endosalpingiosis.

Conclusions

Umbilical endosalpingiosis is a very rare manifestation of the non-neoplasmatic disorders of the Müllerian system. It appears with cyclic symptoms of pain and swelling of the umbilicus, but not always. The disease is diagnosed using pathologic findings and surgical excision is the definitive treatment.

Endosalpingiosis of the urinary bladder: a case of probable implantative origin with characterization of benign Fallopian tube immunohistochemistry

Müllerianosis of the bladder is an infrequently described lesion consisting of multiple Müllerian-type tissues within the urinary bladder. Few previous cases of pure endosalpingiosis have been described. Here we present a 54-year-old post-menopausal female with a history of prior pelvic surgery with traumatic bladder injury, who was found to have a cystic lesion in the posterior wall of the bladder. Routine histology demonstrated cyst epithelium characteristic of endosalpingiosis. Three benign Fallopian tube specimens were obtained and stained with the relevant immunohistochemical markers for comparison. Results showed an identical immunohistochemical profile between the bladder cyst lining and the normal Fallopian tube controls. This case represents a rare instance of pure endosalpingiosis of the urinary bladder, with a likely implantative origin. This form of bladder Müllerianosis should therefore be considered within the differential diagnosis of cystic lesions of the bladder.

Management of endosalpingiosis of urinary bladder

We report on a 48-year-old woman who presented with abnormal uterine bleeding secondary to uterine fibroids and who was found to have incidental endosalpingiosis of the urinary bladder. Follow-up is necessary for bladder endosalpingiosis because of its tendency to recur. Follow-up should include cystoscopy and renal, and possibly pelvic, ultrasonography.

Serous tumor of low malignant potential arising in inguinal endosalpingiosis: report of a case

A 46-year-old woman presented with a right inguinal mass. Imaging studies revealed no abnormalities of the pelvis (including the ovaries) or abdomen. The inguinal mass was composed predominantly of variably sized cysts lined by flat to low cuboidal cells resembling mesothelial cells and ciliated columnar tubal-type cells with a focal transition between the two cell types. Papillae, detached cell clusters with mild cytologic atypia, and psammoma bodies were also found, warranting a diagnosis of a serous borderline tumor. This appears to be the first report of a serous borderline tumor arising in inguinal endosalpingiosis and not associated with an ovarian serous tumor.
