Intravesikale Salpingiose - Fallbericht und Literaturüberblick

Endosalpingiosis of the urinary bladder is a rare benign condition characterised by the presence of ectopic endosalpingeal tissue in the bladder. If histology shows two or more Müllerian-derived components, this condition is referred to as Müllerianosis. To our knowledge less than 20 cases of Müllerianosis and 5 cases of endosalpingiosis have been documented in the literature. Although the pathogenesis remains unclear, two theories exist. The implantation theory assumes that Müllerian-derived tissue gets implanted in the wall of the urinary bladder during pelvic surgery. The second theory proposes a metaplastic origin of the disease. Patients suffering from endosalpingiosis or Müllerianosis may present with symptoms such as suprapubic pain, frequent urination, dysuria or gross haematuria, possibly with a cyclical appearance. We present the case of a 40-year-old female patient, who primarily presented with painful haematuria and was diagnosed with endosalpingiosis and treated by transurethral resection. Also we review the current literature.
