TRACHEA - Adenoid cystic carcinoma

The specimen is old and hence discoloured. The cut ends of the tracheal cartilage can be seen at one side of the specimen; within the trachea there is a nodular tumour some 5.0 cm across which is extending through the tracheal wall. These tumours are uncommon; they infiltrate locally and occasionally metastasise to the hilar lymph nodes.
