Abstract:
A male in his early 20s with gastro-oesophageal reflux disease and severe weight loss was found to have two intrabdominal masses causing his symptoms: one in the gastro-oesophageal junction and the other occupying the coeliac plexus in the cardiophrenic region. These masses were surgically removed and sent to pathology where they were found to be smooth muscle hamartomas with Schwannian components. These represent a unique presentation of benign smooth muscle tumours that is not typically seen in young adults, especially in the cardiophrenic region involving the coeliac plexus.
