title: Primary splenic mesenchymal chondrosarcoma in a dog.
abstract: A large splenic mass was found during exploratory celiotomy in a 12-year-old Labrador retriever. Histologic examination of the mass revealed a mesenchymal chondrosarcoma. The dog was euthanatized 7 wk postoperatively, due to suspected tumor recurrence. Extraskeletal mesenchymal chondrosarcomas are rare in dogs and are associated with a guarded prognosis.
