A third category, "spindle-cell or myxosarcoma
," comprised rare tumors that were thought to derive from the stroma.
In that study, there were no cases of myxoma or myxosarcoma
, and only two neoplasms were diagnosed in pintagols: cloacal papilloma and subcutaneous liposarcoma.
Left atrial myxosarcoma
with systemic metastasis: a case report.
The distinction between a poorly differentiated leiomyosarcoma and other spindle cell tumors such as rhabdomyosarcoma, fibrosarcoma, schwannoma, and myxosarcoma
Soft-tissue sarcomas are tumors arising from extraskeletal connective tissues and from Schwann cells and include fibrosarcoma, liposarcoma, hemangiopericytoma, rhabdomyosarcoma, lymphangiosarcoma, malignant fibrous histiocytoma, leiomyosarcoma, myxosarcoma
, myxofibrosarcoma, mesenchymoma, spindle cell tumors, and malignant peripheral nerve sheath tumors (neurofibrosarcoma, Schwannoma).
To our knowledge, this is the first report of a myxosarcoma
in a bustard species and the first report of successful clinical application of metronomic chemotherapy in an avian species.
