Histopathological Analysis of Tubal Ectopic Pregnancy

Abstract

Ectopic pregnancy (EP) is a critical obstetric condition where the fertilized egg implants outside the uterine cavity, most commonly in the fallopian tube. Tubal ectopic pregnancy is the most common form, accounting for approximately 95% of all ectopic pregnancies. This study aims to analyze the histopathological features of tubal ectopic pregnancy and explore the associated tissue changes that can aid in better understanding and diagnosis. We performed a retrospective analysis of patients diagnosed with tubal ectopic pregnancy, examining histopathological specimens obtained after surgery. The primary histological findings included trophoblastic invasion, decidualized endometrium, hemorrhage, and varying degrees of inflammatory response. The presence of trophoblastic tissue embedded within the tubal mucosa and muscular layers was a consistent finding. Additionally, we observed that the extent of hemorrhage and the degree of tubal damage could be correlated with the clinical severity. Histopathological analysis remains a crucial tool for confirming the diagnosis of tubal ectopic pregnancy and can provide insights into the pathophysiology of this condition, helping to improve early detection and management.
