Fine‐needle aspiration of soft tissue perineurioma: A comparative analysis of cytomorphology and immunohistochemistry with benign and malignant mimics

CONCLUSIONSSTP, intramuscular/cellular myxoma, and LGFMS have significant cytomorphologic overlap. Immunohistochemical staining with EMA is not beneficial due to a lack of specificity. Negative MUC4 staining reliably excludes LGFMS. Therefore, a clinically meaningful approach to the FNA biopsy evaluation of a low‐grade myxoid spindle cell neoplasm is to provide a differential diagnosis and to exclude a low‐grade sarcoma.
