Abstract
Alveolar soft part sarcoma(ASPS) is a rare malignant neoplasm with a distinct clinicopathologic entity of which fine needle aspiration(FNA) cytologic findings have been described in only a few reports. Although patients usually present with an isolated soft-tissue mass in the extremity, metastasis can occur in about 13 % of total cases and the most frequent metastatic site is the lung. We have recently experienced a FNA cytologic case of ASPS in the lung. A 23-year-old female patient was admitted to this hospital due to 2-month-history of cough She had been good in health before the visit. Chest computed tomography revealed multiple, variable sized, bilateral pulmonary nodules. Physical examination and other staging work up revealed no other lesions except for pulmonary nodules. A percutaneous transthoracic FNA was performed from the pulmonary nodules. The smear was cellular and most cells were arranged singly. In addition, a few clusters lined by thin-walled vasculature with a pseudoalveolar pattern were present. Some of the tumor cells were large and polygonal lo oval with abundant granular or vacuolated cytoplasm. Most cells were naked nuclei showing finely granular chromatin pattern with prominent central nucleoli.
