Testicular embryonal rhabdomyosarcoma diagnosed by fine needle aspiration cytology. A report of two cases.

During a 12-year period, 1980-1992, two cases of testicular embryonal rhabdomyosarcoma were diagnosed by fine needle aspiration cytology at the Shiraz University Hospitals. The smears revealed various types of cells including spindle cells, strap cells, rhabdomyoblasts, round cells and tadpole cells with a high nuclear/cytoplasmic ratio. Cross-striations were noticed in the cytoplasm at higher magnification under oil immersion. The cytologic diagnoses of embryonal rhabdomyosarcomas were confirmed on histologic sections.
