Cytological diagnosis of actinomycosis and eumycetoma: a report of two cases.

Mycetoma and actinomycosis are common in tropical countries and are increasingly diagnosed in other parts of the world due to rapid mobilization of the population. They are usually diagnosed on histopathology. There is very limited data on the role of fine-needle aspiration cytology (FNAC) in diagnosing these lesions. We report here two cases: one of eumycetoma and the other of an actinomycosis that were reliably diagnosed with FNAC. The cytological features were similar to histopathology features and differentiated eumycetoma and actinomycosis. FNAC is a rapid, simple and inexpensive outpatient procedure that helps in rapid diagnosis.
