  • Fine-needle aspiration cytology of soft tissue lesions: Diagnostic challenges

    • Clinical and radiographic data provide important information in the evaluation of soft tissue lesions/neoplasms. Morphologic tissue and cytologic examination is considered to be a necessary part of the diagnostic work-up. The standard procedure for obtaining tumor tissue for morphologic evaluation has been incisional (open) or core needle biopsy. An increasing use of minimally invasive diagnostic procedures has resulted in better acceptance of fine-needle aspiration cytology (FNAC) in the diagnosis of soft tissue lesions. This article discusses challenges in FNAC of soft tissue lesions based on the experience at a multidisciplinary referral sarcoma center. Obtaining sufficient specimens from deeply seated small and necrotic/cystic lesions is technically a potential pitfall and misdiagnosis of cells from reactive zones surrounding the tumor as well as the correct evaluation of spindle cell lesions, rare soft tissue neoplasms, and "new entities" lacking reproducible cytological criteria are other important challenges in FNAC of sofa tissues. The succes, successful cytological evaluation of soft tissue lesions requires the application of strict, reproducible morphological criteria in the context of the clinical findings as well as ancillary techniques. The minimal criteria for diagnostic intervention in various clinical settings and the relative advantages and disadvantages of FNAC must be understood. FNAC (of soft tissue lesions is facilitated when limited to specialized orthopedic-oncologic centers with a well- integrated multidisciplinary team and experience in the evaluation and therapy of soft tissue lesions.

  • Fine needle aspiration diagnosis of spindle cell tumors of soft tissue, including the use of ancillary methods, and correlation with clinical data.

    • Fine needle aspiration cytology (FNAC) is gaining increased popularity in the diagnosis of soft tissue lesions. FNAC used as a primary examination method to obtain a morphologic diagnosis, has been part of the diagnostic work-up of patients admitted to the Musculoskeletal Tumor Center of the Lund University Hospital since 1972. Accuracy of FNAC in distinguishing benign from malignant soft tissue tumors has been comparable to that of surgical biopsies, while its accuracy in establishing a specific subtype diagnosis has been inferior to surgical biopsies. The cytological examination of spindle cell tumors of soft tissue, which often share morphological and clinical characteristics, is a challenge. In addition, the literature on FNAC of spindle cell tumors is still sparse. The purpose of this study was both to describe the spectrum of FNAC findings in spindle cell tumors of soft tissue and also to analyze which ancillary methods can optimize FNA cytodiagnosis among these tumors in order to minimize the need for open biopsy. To this end, 238 FNA aspirates performed on 236 patients with five selected types of spindle cell tumors of soft tissue were analysed. In addition, clinical information and ancillary studies, which could increase the precision of cytodiagnosis were evaluated. The results of the study indicate the following: Different treatment options for some low grade and local aggressive/benign spindle cell tumors require an exact histotype diagnosis. This can be usually obtained from aspiration smears complemented by clinical data in elastofibroma dorsi and spindle cell lipoma due to their characteristic cytomorphology. FNAC evaluation of neurilemoma (schwannoma), leiomyosarcoma and dermatofibrosarcoma protuberans, requires the use of strict cytological criteria together with proper clinical information and often ancillary techniques. Correct cytologic diagnosis of spindle cell tumors is facilitated when fine needle aspiration cytology is used in the context of the clinical findings and when the cytological diagnosis is based on strict cytological criteria as well as ancillary techniques.

  • Low-grade fibromyxoid sarcoma is difficult to diagnose by fine needle aspiration cytology: a cytomorphological study of eight cases.
  • 2009
  • Ingår i: Cytopathology. - : Wiley. - 1365-2303 .- 0956-5507. ; 20, s. 304-314
  • Tidskriftsartikel (refereegranskat)abstract
    • Background: Low-grade fibromyxoid sarcoma (LGFMS) is an uncommon neoplasm with bland morphology and an indolent clinical course, although metastases may develop in approximately 5-10% of the cases. The diagnosis of LGFMS can be difficult to render from fine needle aspiration cytology (FNAC) alone because of morphological overlap with other spindle cell and myxoid lesions. Objective: To determine cytological criteria for LGFMS by reviewing FNAC aspirates in eight cases and to compare the findings with those in subsequent histological sections. Methods: FNAC slides were reviewed from eight patients with subsequently excised tumours diagnosed as LGFMS. Of these patients, six also had core needle biopsies (CNB). Cytogenetic and/or molecular analysis was carried on all tumours. Results: The patients were six men and two women ranging in age from 26 to 78 years. Tumours arose in the deep soft tissues of the thigh (n = 5), shoulder girdle (n = 1) or upper arm (n = 1) and one in the subcutaneous tissue of the abdominal wall. Cytological features included clusters of bland spindle and round/polygonal cells embedded in a collagenous and myxoid matrix along with dissociated, uniform or slightly/moderately pleomorphic spindle cells, bare nuclei and fragments of collagen and myxoid tissue in varying proportions. Unequivocal sarcoma was diagnosed in two aspirates, but mitoses were absent in all cases. In three cases, the diagnosis was inconclusive with regard to benignity or malignancy, while three were erroneously diagnosed as benign spindle cell lesions. Although the diagnosis was suggested on three of six CNB, these presented similar diagnostic problems. Conclusions: There were no cytomorphological findings in FNAC to allow for a clear cut separation of LGFMS from other spindle cell or myxoid lesions, but high-grade sarcoma could be excluded. Surgical (incisional or excisional) biopsy or, alternatively, examination of RT-PCR for the FUS/CREB3L or FUS/CREB3L1 fusion transcripts may be necessary to obtain a correct diagnosis.
