Respected sir, thank you for sharing this case Smears from a paravertebral mass is highly cellular and show branching sheets, clusters and singly scattered oval to round cells with hyperchromatic nuclei, regular uniformly dispersed chromatin exhibiting mild anisonucleosis and moderate to scant cytoplasm. Few rosettes or acini formation are noted. Occasional mitotic fig are seen. No necrosis is noted. No multinucleate cells or myxoid background or neurophil background or lymphoglandular bodies are seen. Impression : FNA from paravertebral mass showing a SMALL ROUND CELL TUMOUR. D/D: 1. Ewing/PNET 2. Alveolar RMS 3. Synovial sarcoma 4. Rare : DSRCT, Small cell Osteosarcoma, lymphoma/leukaemia, Rhabdoid tumour. Suggestions : 1. Core biopsy with IHC for Subtyping. Panel: CK, VIMENTIN, LCA, MYOGENIN, CD99, BCL2, TLE 1 2. Sir, requires radiological correlation (MRI scan to look for plane of the swelling, nature and necrosis, etc) Thank you sir. Regards...
cellular smears. Most of the cells are arranged in papillary , branching pattern. occasional acini are noted. cells are uniform. Hyperchromatic nuclei. mild anisonucleosis and scanty cytoplasm.. possibility of 1. synovial sarcoma 2. Alveolar RMS 3. Rule out RCC papillary form. Though it is rare in this age 4. secondary deposit from papillary carcinoma thyroid require radiological correlation
