Patient with protracted abdominal pain

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. 1 Early diagnosis may prevent invasive investigations and radical surgical procedures as the patient can then simply be treated with oral penicillin. 2
