摘要
Rationale: Schwannomas of gastrointestinal tracts are rare and difficult to detect preoperatively because of negative results of endoscopic and imaging examinations. Here, we reported a case of rectal schwannoma, which was diagnosed by immunohistochemical staining after laparoscopic protectomy. @@@ Patient concerns: A 61-year-old woman complained of a 1-month history of difficulty in defecation and irregularly abdominal discomfort during her physical checkup in our hospital. @@@ Diagnoses: Immunohistochemical staining results after laparoscopic protectomy revealed a strong positive reaction for S-100 protein. Therefore, rectal schwannoma was confirmed. @@@ Interventions: Treatment with laparoscopic protectomy was given. @@@ Outcomes: Symptoms resolved completely after 12 days of the surgery, and was regular followed-up in outpatient clinic. @@@ Lessons: Schwannomas are difficult to identify preoperatively, and immunohistochemical staining for S-100 protein is an effective method to diagnose it.
