[Triton's malignant intrapulmonary tumor]

Abstract

The authors report a case of an intrapulmonary tumour which on histological analysis was found to be a malignant Triton tumour after surgical excision. The tumours proved to be of nervous tissue origin and was a rare variant of malignant tumours of the surrounding of peripheral nerves with rhabdomyoblastic heterologous differentiation which is rarely described in the lungs. The characteristics of the tumour as well as therapeutic approaches are discussed followed by a review of the literature. A particular aspect of the case presented was to realise that there was a right to left shunt and this is also discussed.
