Multifocal osteosarcoma with extensive pleural metastatic disease.
An eighteen year old female presented with multifocal synchronous osteosarcoma, with multiple skeletal foci of tumour in long bones, pelvis and spine. The radiographically dominant lesion was in the right ilium, and this was considered to be the primary site. There was an extensive osseous pleural plaque and there were also metastases to lungs, peritoneum, abdominal wall, adrenal gland and lymph nodes. A review of the literature reveals that multifocal osteosarcoma is an uncommon condition and is probably due to metastatic disease and not multiple primary lesions. Pleural metastatic disease in osteosarcoma has been seldom reported.
