摘要: Background Rhabdomyosarcoma is the most common soft tissue sarcoma of children < 15 years age. Case We report a case paratesticular rhabdomyosarcoma diagnosed by fine needle aspiration (FNA) in an 18-year-old man with enlargement right testis. The FNA material revealed mainly isolated small to median-sized malignant cells various shapes. Among these, large rhabdomyoblasts were observed. Some neoplastic showed longitudinal striations. Immunocytochemistry was strongly positive against vimentin and desmin, results for cytokeratins, smooth muscle antibody, epithelial membrane antigen, S-100 neuron-specific enolase negative. Histologic examination surgical specimen agreement findings. Conclusion safe accurate procedure, without implications, that could be used outpatient setting, allowing preliminary, preoperative diagnosis, even tumors.
