title: Curschmann's spirals and actinomycosis in a fine needle aspirate of the parotid.
abstract: Fine needle aspiration (FNA) of bilaterally enlarged submandibular salivary glands yielded both Curschmann's spirals and actinomycetes filaments in the FNA smears. Histologic study of specimens from the bilateral submandibulectomy confirmed the actinomycosis but failed to demonstrate the presence of spirals. The presence of Curschmann's spirals in FNA material is a finding not previously described in the English literature. Actinomycosis, although well documented in exfoliative cytology, has been rarely reported in fine needle aspirates. This unique case afforded the opportunity of illustrating the characteristic features of Curschmann's spirals and actinomycetes colonies, as well as reviewing the etiology and pathogenesis of Curschmann's spirals, in FNA material.
