title: Actinomycosis, a sheep in wolves' clothes.
abstract: We present a patient referred for radiotherapy for a presumed pulmonary malignancy, who was found to suffer from an actinomycotic infection. This case illustrates the importance of early consideration of actinomycosis when diagnostic methods are negative for malignancy or specific chestwall and bony lesions are observed.
