Introduction: Cecal endometriosis is an infrequent cause of right iliac fossa pain. The extra-uterine retroperitoneal cellular leiomyoma is a rare tumor. The concurrent existence of both these rare conditions is a unique event.
Presentation of case: We hereby report the case of a 44-year-old woman who had concurrent large isolated cecal endometrioma, which was diagnosed pre-operatively on imaging to be pelvic endometriosis/hematosalpinx and solitary retroperitoneal cellular leiomyoma, which was incidentally identified. Both the conditions were managed successfully by laparoscopy.
Discussion: Cecal endometriosis is difficult to diagnose pre-operatively as there are far commoner clinical conditions that cause similar signs and symptoms. Often it gets mistaken for these conditions and gets diagnosed incidentally 'on table' during surgeries being performed purportedly to treat them.
Conclusion: Although definitive diagnosis can only be obtained after histopathology, laparoscopy can be considered a standard diagnostic modality for both these conditions.
