Malignant mesothelioma presenting as pulmonary metastasis ahead of growth of primary tumour
A 59-year-old woman was admitted to Houju Memorial Hospital, Ishikawa, Japan, because of cough and fever on 30 March 1997. A diagnosis of pneumonia was made and she was given antibiotics. Her symptoms improved but failed to resolve completely on antibiotic therapy. On 9 September 1997, she revisited the hospital because of bodyweight loss and malaise. There was no history of exposure to asbestos. The chest roentgenogram revealed infiltrative shadows with vague and indistinct margins suggesting inflammatory processes, which were more extensive than those investigated on her last visit. One month later, a giant tumour was detected rapidly growing from the mediastinum and open biopsy was performed. The histological examination confirmed that the tumour was a malignant mesothelioma and the intrapulmonary nodules were its metastases. This is a rare case of pulmonary metastasis being present for several months before an appearance of primary mesothelioma.
