title: Tigroid background in fine-needle aspiration cytology of clear cell sarcoma.
abstract: Clear-Cell Sarcoma (CCS) is a rare malignant soft tissue tumor of young adults that often metastasizes to the lymph nodes. The fine needle aspirate cytology (FNAC) findings of CCS have been described previously and it is included in the cytological category of polygonal soft tissue tumors. We describe the cytology of a case of CCS, with emphasis on the so called "tigroid background." Though this tigroid background is a nonspecific feature and has been described in various other tumors, to the best of our knowledge, it has not been described in CCS. This feature may be useful in the recognition of CCS.
