[Cytologic diagnosis of soft tissue tumors].
Soft tissue swellings represent common clinical signs of a variety of neoplastic and non-neoplastic lesions. Sarcomas are rarely the cause. Fine needle biopsy as a minimally invasive, economic and accurate method is well suited for the diagnostics of recurrent and metastatic diseases. Cytologic diagnosis of primary soft tissue tumors is also feasible but requires close collaboration with other medical disciplines and incorporation of clinical, radiological and morphologic findings. Clinical data such as age, gender, size and topography are also important parameters. Differentiation of the cells and the properties of the extracellular matrix offer initial indications for the differential diagnosis and are the starting point for immunohistochemical and molecular analyses (FISH, RT-PCR). These analyses can be performed on cytological smears, on paraffin-embedded cell blocks on snap frozen material.
