Concurrent systemic cryptococcosis and haemangiosarcoma in a dog.

A young dog with progressive neurological signs was humanely killed by the injection of barbiturate for postmortem examination. Lesions in the nose, lung, pancreas, lymph nodes, kidneys and the meninges were heavily infiltrated with Cryptococcus neoformans. In addition, haemangiosarcoma was detected in the right atrium. The finding of systemic mycosis and neoplasia together in a young dog suggests an immunosuppressed state.
