Background and Objectives: Fallopian tubes are the common specimens received in the histopathology laboratory. The recent concept of fallopian tube epithelium as a main source for tubal, ovarian and pelvic carcinoma is becoming common, hence proper examination of fallopian tube is essential. The aims and objectives of this study is to describe various histomorphological aspects of lesions of fallopian tubes. Materials and Methods: Present study is a prospective descriptive study. A total of 361 fallopian tubes specimens were included, these were routinely processed and sections of 5 micron thickness were taken and stained with Hematoxylin and eosin. Detailed gross and microscopic examination was done. Special stains like PAS and modified ZN stain were done wherever necessary. Results: Total of 361 fallopian tubes were analyzed, 49.045% (n=177) cases were unremarkable on both gross and microscopic examination. Salphingitis was seen in 16.36% (n=59) cases which includes acute, chronic, tuberculous and foreign body granulomatous salphingitis. Ectopic pregnancy in 2.78%(n=10) cases, endometriosis in 0.58%(n=2) cases, Salphingitis isthimica nodosa in 0.84%(n=3) cases, primary fallopian tube carcinoma in 0.27%(n=1) and metastatic deposits in 1.1%(n=4) cases. Conclusion: In the present study most patients (86.89%) had the fallopian tubes removed as a part of hysterectomy which was done for other causes rather than tubal pathology. It was observed that almost half of them had tubal pathology. The present study has made a meticulous attempt and studied the gross and microscopic features and categorized the lesions into various groups. Early and correct diagnosis of these diseases will definitely help clinicians in initiation of prompt therapy against the disease.
