The initial approach to the patient with a presumed palpable mass is to ensure that there effectively is a mass corresponding to the palpated finding, which in fact is not the case in around 20% of cases (e.g. pseudomass produced by cecum filled with fecal material). Moreover, the “mass” may be located within the abdominal wall (hematoma, abscess, hernia, tumor, etc.).
