Abstract
INTRODUCTION AND IMPORTANCE: Cystic endosalpingiosis is a rare, benign condition characterized by the presence of fallopian tube-like epithelium outside the fallopian tubes. It predominantly affects menopausal women and is often asymptomatic. Florid cystic endosalpingiosis, an unusual form, can mimic malignant ovarian masses, making accurate diagnosis crucial. CASE PRESENTATION: We present a 48-year-old postmenopausal woman with chronic pelvic pain, found to have a suspicious multicystic mass during ultrasound. Laparoscopic exploration revealed extensive cystic endosalpingiosis involving the uterine surface and left adnexa. Histopathological analysis confirmed the diagnosis. CLINICAL DISCUSSION: Endosalpingiosis often presents a diagnostic challenge due to its nonspecific symptoms and potential to mimic neoplastic conditions. This case underscores the need for histological examination to differentiate between benign and malignant pelvic masses. Surgical resection is recommended for symptomatic cases, while asymptomatic ones may not require intervention. CONCLUSION: Florid cystic endosalpingiosis should be considered in the differential diagnosis of multicystic pelvic masses in menopausal women. Accurate histological diagnosis is essential to exclude malignancy and guide appropriate management.
