Yersinia pseudotuberculozis (YP) infection has increased especially in developed countries. YP rarely causes lymphadenitis and abdominal mass in the right lower quadrant that patient should be operated fort his reason. Our case is 12 years old girl with abdominal pain, vomiting that she has mass in the left quadrant. Firstly, diagnostic laparoscopy was performed, left lower quadrant mass was detected and laparotomy was performed. We thought that this mass could be YP during surgery because we detected lenfadenitis and abscess. Consequantly abscess drainage, mesentery and lymph node biopsy were done in laparotomy. The diagnosis was confirmed with seroloc and pathology. The patient was discharged on 10th day after surgery. The third postoperative month, the clinical and ultrasound findings were normal.Imaging techniques with long-term abdominal pain and abdomen mass in some patients are not sufficient for the differential diagnosis. YP should be considered in the differential diagnosis of masses that the surgeon's dilemma. Serological analysis will provide a correct diagnosis of the patients with YP and prevent to unnecessary surgical intervention.Key Words: Yersinia Psödotuberculosis; Abdominal Pain; Mass; Child
