Fine needle aspiration cytology in mediastinal myxoid liposarcoma: a case report.
BACKGROUND
The mediastinum is an uncommon site for liposarcoma, with <1 % of all tumors occurring in this site.


METHODS
A 40-year-old woman presented with superior vena caval syndrome. Radiologic investigations revealed the presence of a large soft tissue mass occupying the anterior and middle mediastinum. A computed tomography (CT)-guided fine needle aspiration cytology (FNAC) sample showed the presence of fibrillary myxoid material with arborizing blood vessels and atypical lipoblasts. A diagnosis of myxold liposarcoma was made, which was later confirmed on bistopathology.


CONCLUSIONS
The mediastinum is a challenging area for FNAC, which is a useful tool for accurate diagnosis. Awareness of the presence of liposarcoma is important for its recognition.
