The Great Imitator: Cervicofacial Actinomycosis Masquerading as Cancer Recurrence

AbstractCervicofacial actinomycosis being one of the unusual infections is of high relevance to a head and neck onco-surgeon. As the diagnosis may be made difficult by its nature to mimic malignancy and egregiously low culture sensitivity, the differential diagnosis for a lesion appearing to be malignant after irradiation does not usually include actinomycotic infection. Treatment usually requires a long-term antibiotic course after confirmation with histopathology, albeit surgical debridement is required in selective cases. Here we report two cases that were clinico-radiologically diagnosed as osteoradionecrosis and histopathological analysis done to rule out cancer recurrence. Unanticipated, they turned out to be cervicofacial actinomycosis, subsequently treated with long-term antibiotics following which the infection subsided.
