title: Metastatic myxoid liposarcoma of lung and mediastinum diagnosed by fine needle aspiration.
abstract: Myxoid liposarcomas metastatic to lungs and mediastinum are infrequent lung neoplasms. The tumor has an aggressive course and needs to be recognized cytologically. A 60-year-old male smoker presented with gradually progressive left-sided chest pain, cough, and expectoration for the past one month. Chest radiograph and computed tomography of thorax revealed a lung mass in left apical region extending into the posterior mediastinum, which was subjected to ultrasound-guided fine needle aspiration (FNA). Smears showed a cellular tumor with ovoid to spindle shaped tumor cells in a myxoid background having a rich vascular network. The possibility of a myxoid liposarcoma metastatic to lung and mediastinum was suggested and confirmed by histopathology. A previous history of excision of a tumor in the thigh one and half years ago was present. The importance of recognizing the cytological picture by FNA is discussed.
