Objective: to show an infrequent case of presentation of a Schwannoma in a patient with a pre-operative diagnosis of right colon tumour. Case presentation: A 53 years old woman with an abdominal mass in right hypochondrium, weight loss and dyspepsia. The patient underwent surgery for removing the tumour. The pathological study of the surgical piece confirms the diagnosis of Schwannoma. The patient had a satisfactory evolution. Conclusions: The election treatment of Schwannomas is surgery. Although it is important to have the pre-operative diagnosis of these tumours for the realization of surgery, not always the positive diagnosis is available.
