[Surgical Resection of an Ascending Colon Tumor Suspected to Represent Intestinal Behçet's Disease-A Case Report].

A 63‒year‒old female presented with epigastric pain and loss of appetite. Upon further examination, a deep ulcer in the ileocecal region causing obstruction was diagnosed. Despite conservative treatment, there was no improvement, and laparoscopic ileocecal resection was performed. Histopathological examination of the excised specimen revealed multiple signs of vasculitis, and the patient was found to be HLA‒A26 positive, raising suspicion for intestinal Behçet's disease. However, due to the absence of the hallmark symptoms, a definitive diagnosis could not be made. Intestinal Behçet's disease is a challenging, refractory condition with a complex diagnosis, and further accumulation of cases and long‒term follow‒up are necessary for better understanding and management.
