Giant cell tumour of soft part is a very rare neoplasm. The majority of these tumours are located superficially (in subcutaneous tissue) and occur in the proximal parts of the extremities. The deep-situated giant cell tumours of the neck are extremely rare. That is why we report a case of primary giant cell tumour of soft part localized in the trapezius muscle of a 19-year-old woman. We present both cytological and histological picture of the neoplasm. The cytological image of the smear is so representative that the proper diagnosis can be settled basing on the fine-needle aspiration cytology.
