Actinomyces is a commensal in the oral cavity, digestive tract and genital tract. However invasive Actinomycosis occurs when the host immunity is breached due to local or systemic immune compromised states. The most common presentation is a slowly growing mass with cutaneous draining sinuses. However the presentation is varied. There are cases of actinomycosis mimicking as tuberculosis and malignancy. The diagnosis is very important as the management varies drastically depending on the diagnosis. This case report highlights the unique presentation of actinomycosis in clinical and radiological diagnosis. Hence histopathological diagnosis is always mandatory in the diagnosis of actinomycosis.
