PURPOSE. The purpose of this article was to report an unusual presentation of abdominal actinomycosis masquerading as a tumor. METHODS: The patient was a 54-year-old male who presented with vague abdominal discomfort and a palpable left lower quadrant mass defined on CT scan. Multiple intraoperative core biopsies were nondiagnostic, and he underwent en bloc resection of the mass and adjacent organs for a presumed tumor. RESULTS: Examination of tissue from deep within the excised specimen revealed sulfur granules diagnostic for actinomycosis. CONCLUSION: Abdominal actinomycosis is an extremely rare infection that can mimic multiple disease processes and requires accurate diagnosis for successful therapy. This novel presentation and a review of the literature are reported.
