Introduction: Extraskeletal myxoid chondrosarcoma (EMC) is a rare cartilage tumor comprising 1% to 3% in all soft tissue malignancies. Limited literature available on its cytological features and the diagnostic modality of FNAC. Here, we report a rare case of extraskeletal myxoid chondrosarcoma on FNAC. 40 years female presented with swelling on right waist, rapidly increasing in size and pain since 2 months to present with size of 25x25x10 cm, firm to hard, for which FNAC done. X-ray showed in-homogenous opacity and calcification, bony cortex is intact without erosion. Aspirate showed uniform cells of small to medium size, arranged in chords and clusters embedded in abundant myxoid background. In view of clinical history and radiology, cytological diagnosis of extraskeletal myxoid chondrosarcoma was suggested and confirmed by histopathology. On light microscopy it shows obvious chondroid differentiation, so it needs to be distinguished from other chondromyxoid soft tissue swellings. This case emphasizes diagnostic role of FNAC at rural based hospital devoid of adequate radiological support, immunohistochemistry and other ancillary techniques.
