Abstract 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 fallopian tube tumors and tumor like lesions. 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. Results: Total of 361 fallopian tubes were analyzed, pathological lesions were seen in 50.96%(n=184) cases. Out of which 1.38%(n=5) cases showed features of malignancy with primary fallopian tube carcinoma(PFTC) accounting for 0.27%(n=1) cases and metastatic carcinoma accounted for 1.11%(n=4) cases. Tumor like epithelial lesion included salpingitis isthmica nodosa(SIN) which was seen in 0.85%(n=3) 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 of fallopian tube tumors and tumor like lesions and categorized the lesions into various groups.
