This aged (25 years), captive, male lizard (weight 623 g) was found to have an oral mass on the right side of the maxilla resulting in tooth displacement. When touched, teeth easily fell out. The mass was reported to have developed within a two week period. Two weeks prior, the shingleback was reported to develop a weeping eye and display rapid breathing after a short period of handling. The animal had a history of conjunctival swelling and depression.
