- Abstract: A 48-year-old, non-hypertensive, non diabetic man with uncontrolled gouty arthritis presented with a four-day swollen nasal mass. He was assessed to have a nasal abscess at the emergency room and was admitted for urgent management. Paranasal computed tomography (CT) scans showed a heterogeneously enhancing focus with areas of hypodensities in the nasal apex and dorsum extending into the right ala measuring 1.5 x 2.8 x 3.4 cm. with associated erosion of the cartilaginous part of the anterior nasal septum, soft tissue swelling and skin thickening in the nasal dorsum, nasal tip and right zygomatic region that was suspected to relate to an aggressive etiology. Tissue correlation was therefore recommended, and he underwent endoscopic-guided incision and drainage with biopsy and debridement of the nasal mass. The specimen submitted consisted of red to white, irregular, soft tissue fragments with an aggregate measurement of 1.5 x 1.5 x 0.5 cm. Microsections showed deposits of amorphous white to pink material with surrounding fibrosis and acute and chronic inflammatory cell infiltrates and foreign body giant cells. (Figures 1 and 2) Also seen in the background were fragments of sclerotic bone and bacterial colonies. These findings were consistent with gouty tophus with acute and chronic inflammation and bacterial colonization. The culture and sensitivity test of the nasal discharge showed growth of Enterobacter aerogenes (currently named Klebsiella aerogenes) which was identified by an automated mass spectrometry microbial identification system (VITEK® MS). Work-up also included uric acid levels which were within the reference interval at that time (6.57 mg/dL).
