spindle cell sarcoma

A nonspecific term of uncertain clinical utility given that many sarcomas, regardless of type of mesenchymal differentiaton (leiomyosarcoma, fibrosarcoma/malignant fibrous histiocytoma, rhabdosarcoma) are composed of elongated plump (“spindled”) cells.

spindle cell sarcoma

A sarcoma consisting of small and large spindle-shaped cells.

15) The dove in this report had a spindle cell sarcoma mass identified 8 months after the initial diagnosis of osteosarcoma.
Immunohistochemical staining for osteocalcin and osteonectin was performed in this case in an attempt to further classify the identified spindle cell sarcoma.
The most common morphologic categories in which it was used include high-grade round cell sarcomas, nonmyogenic spindle cell sarcomas, low-grade myxoid neoplasms, adipocytic neoplasms, and melanocytic neoplasms, in descending order of frequency.
The histopathological report confirmed a high-grade spindle cell sarcoma that had been completely excised with 2mm margins.
The diagnostic challenge of MPNSTs resides mainly in distinguishing them from other spindle cell sarcomas, such as fibrosarcoma, monophasic synovial sarcoma, leiomyosarcoma, and neurotrophic/desmoplastic melanoma.

Malignant perineurioma is very rare, and its diagnosis may be difficult without confirmatory ultrastructural studies (41) because EMA positivity is also seen in other high-grade spindle cell sarcomas (eg, epithelioid sarcoma and monophasic synovial sarcoma), as well as in spindle cell squamous cell carcinoma.
It was reported that all synovial sarcomas, whether monophasic fibrous or biphasic, expressed E-cadherin, indicating E-cadherin as a marker for differentiation between synovial sarcomas and other types of spindle cell sarcomas.
