Kowari thoracic fibrosarcoma

1. Harold Dallas Attwood (b.1928, d.2005)
2. Patricia Woolley (b.1932)
Circa 1973
Dissected fibrosarcoma from a kowari (Dasyuroides byrnei), a small carnivorous marsupial. This specimen was figured in the paper, 'Spontaneous malignant neoplasms in dasyurid marsupials', published in the Journal of Comparative Pathology by H.D. Attwood (Pathology Dept. University of Melbourne) and P.A. Woolley (Zoology Dept. La Trobe University) in 1973. From the paper: 'A male Dasyuroides byrnei estimated to be 4 years old, was killed some 44 months after capture because of obvious respiratory distress. Three days before, it had been lethargic, but otherwise well. At necropsy, the only macroscopic abnormality was the crowding of the thoracic cavity by smooth, bossellated tumours (0.3 to 2.5 cm. in maximum diameters) which originated from the internal aspect of the rib cage. The tumours greatly compressed the heart and lungs, but these could be easily dissected from the vertebral column and were in no way adherent to the tumours. On the right side the tumours were entirely within the thorax, but on the left side the largest tumour extended into the subcutaneous tissues. On section this tumour was white, lobulated, partly cystic and partly solid and appeared to have destroyed several ribs.'
