title: Primary cardiac spindle cell tumor in a dog.
abstract: An adult Labrador retriever dog was presented with respiratory signs and heart murmur. Echocardiography and thoracic radiographs revealed a heart base mass infiltrating the left atrial wall. Microscopically, neoplastic tissues consisted of spindle cells and abundant extracellular matrix. Based on histochemical stain and immunohistochemistry, a diagnosis of primary cardiac sarcoma was made.
