Fine needle aspiration cytology in the diagnosis of non-neoplastic diseases of head and neck masses.

In this study, 3 patients with head and neck masses, which were suspicious of neoplastic compromise, were submitted to FNAC investigation. Two cases showed specific infection by Paracoccidioidomycosis and one by Actinomycosis. The cytologic findings were in agreement with histopathologic diagnosis and clinical follow-up; that results showes that FNAC importance in the diagnosis of non-neoplastic masses could be explored in ambulatorial routine.
