Phytobezoars are concretions of indigestible plant materials in the gastrointestinal tract. While Diospyros lotus-related bezoars are typically found in the stomach or small intestine, rectosigmoid localization is rare. Such bezoars may mimic other gastrointestinal conditions, including irritable bowel syndrome (IBS).A 48-year-old male presented with abdominal bloating, pain, and a sense of incomplete defecation for several weeks. He had no known systemic disease or regular medication use. He reported consuming large quantities of Diospyros lotus fruit from a tree in his garden shortly before symptom onset.Colonoscopy revealed two bezoars, each 3–4 cm in diameter, located in the rectum and sigmoid colon. These were fragmented and removed using a snare and basket catheter. A small number of Diospyros lotus seeds were identified within the bezoars. At follow-up, the patient was symptom-free.Rectosigmoid bezoars are uncommon and usually linked to seed ingestion (e.g., pumpkin, watermelon). Diospyros lotus typically causes gastric phytobezoars or small bowel obstruction. In this case, bezoar formation in the lower colon likely resulted from impaired passage due to anatomical narrowing. The symptom pattern resembling constipation-dominant IBS adds clinical complexity and underscores the need for thorough evaluation in similar cases.This rare case highlights that Diospyros lotus can cause phytobezoars beyond the stomach, including the rectosigmoid colon. Clinicians should consider bezoars in the differential diagnosis of chronic constipation-like symptoms, especially with a relevant dietary history.
