BACKGROUND: The diagnosis of metastatic poorly differentiated rhabdomyosarcoma (RMS) in lymph node specimens by fine needle aspiration presents a difficult problem since it is virtually indistinguishable from other small round cell neoplasms.
CASE: Fine needle aspiration was performed under radiologic guidance on an extradural, space-occupying lesion of unknown etiology in the region of the C-6 and C-7 vertebrae in a 20-year-old male who was hospitalized with quadriparesis. Cytologic examination suggested a metastatic tumor consistent with the diagnosis of rhabdomyosarcoma. A subsequent search for the primary tumor site revealed a soft tissue swelling in the right calf muscle. Light microscopic, ultrastructural and immunocytochemical examination of multiple Tru-cut biopsy specimens from the swelling in the right calf muscle confirmed the diagnosis of poorly differentiated embryonal rhabdomyosarcoma.
CONCLUSION: Immunostaining is useful for muscle proteins in the detection of poorly differentiated forms of embryonal rhabdomyosarcoma. Electron microscopy is of limited use in such cases.
