Inflammatory cloacogenic polyps are rare and often discovered either during routine colorectal cancer screenings or in symptomatic patients presenting with hematochezia. In unusual cases, they can present as an adhesive obstruction with radiological and clinical findings suggestive of a suspicious recurrent colorectal malignancy lesion. Because these polyps can mimic cancer during endoscopy, a detailed tissue examination is crucial for making the correct diagnosis and planning treatment. In this report, we share a challenging case where a patient with a history of cancer presented with signs that strongly suggested a malignant recurrence, but the final diagnosis was an inflammatory cloacogenic polyp. This case highlights the critical role of regular endoscopic monitoring in managing such complex conditions.
