To the Editor, Choristoma is defined as the presence of histologically normal cells in abnormal locations due to defects during embryological development (1). The criteria for the diagnosis of choristoma are a tumour-like growth, an ectopic tissue with a normal pattern and without neoplastic features histologically, and a mislocated tissue topographically. It is different from hamartoma because the hamartoma appears in normal locations. Laryngeal choristomas are rare lesions and are usually relevant to glial or thyroid tissues (2). Salivary gland choristomas (SGC) in the cheek, middle ear, neck, jaw, thyroid gland, pituitary gland, mediastinal lymph nodes, breast, anterior chest wall, oesophagus, duodenum, jejunum, rectum and amygdala have been reported (3).
