Actinomycosis is very often misdiagnosed as typically, the
associated laboratory and radiological findings are nonspecific.
Therefore, clinicians should always have a high index
of suspicion in cases in which there is a chronic, indolent
development of a mass lesion with sinus tracts, that progresses
through the tissue planes, and which relapses following short
courses of antibiotics. Early diagnosis may prevent invasive
investigations and radical surgical procedures as the patient
can then simply be treated with oral penicillin.
