title: Malignant chondroid syringoma presenting as multiple pulmonary nodules.
abstract: Malignant chondroid syringoma, a very rare tumour, presenting with multiple pulmonary metastases in a 50 year old woman is described. Initial diagnostic confusion with pulmonary hamartoma occurred due to histopathological similarities. However, re-examination of a skin biopsy specimen taken 17 years previously from a hand lesion yielded the necessary information to identify the pulmonary lesions definitively as metastases from the original skin lesion. The features of this very rare indolent tumour are described.
