Description Of An Anaplastic Rhabdomyosarcoma In A Cockatiel (Nymphicus Hollandicus)
Rhabdomyosarcoma is a malignant tumor of the skeletal muscles that is occasionally observed in free-living and pet birds. A case of malignant rhabdomyosarcoma in the musculature of the right wing of a captive female cockatiel (Nymphicus hollandicus) was investigated. The clinical aspect and radiogra...
