title: Pedunculated intraluminal osteochrondromatous hamartoma of the esophagus.
abstract: Pedunculated intraluminal hamartoma of the cervical esophagus of an adult female was treated by surgical resection. The patient presented with bloody sputum. A barium swallow revealed a pedunculated intraluminal tumor just below the conus of the thyroid cartilage. The tumor had a stalk of 6 cm in length and was attached to the cricopharyngeal muscle. Histopathologic examination showed a predominance of osseous and cartilaginous tissue. The tumor also contained fibrous tissue, adipose tissue and glandular structure. The embryology of such a cartilaginous tumor at the proximal esophagus was interesting.
