“…Tophaceous gout is characterized by macroscopic deposits of urate crystals found in periarticular and subcutaneous tissues, which predominantly are seen in the fingers, knee VOLUME 7 | NUMBER 6 | NOVEMBER/DECEMBER 2015 joints, volar aspect of the forearm, or helix of the ear (Gupta, Rai, Sinha, & Achar, 2009). Causes for elevated serum urate levels are decreased renal excretion, increased production of urate, and increased purine-rich foods (Chen & Schumacher, 2008).…”
Tophaceous gout, presenting as nodules on the skin, is uncommon and can be mistaken for neoplasms. These nodules may not be recognized as gout because the clinical diagnosis of tophi gout is not always straightforward with typical symptoms. The cause for tophi gout is elevated serum uric levels, which result from decreased renal excretion, excessive production of urate, and a diet of purine-rich foods. Complications from tophi crystals may occur and can lead to secondary infections, decreased functionality of movement, and disfigurement. Patients need to be treated for acute attacks with complete resolution before long-term treatment is initiated to prevent an increase in the inflammatory cascade. Medications are effective in lowering urate levels and dissolving tophi, but the addition of dietary restrictions is also important to prevent reoccurrence of tophi crystals. Educating patients on early treatment of acute attacks and chronic treatment of high urate levels, along with dietary modification, lessens the possibility of complications that can occur from tophaceous gout.

Gout is a disorder of uric acid metabolism that causes deposition of Monosodium Urate (MSU) crystals in joint spaces, which, in turn, elicit an acute inflammatory reaction. We present a case in which diagnosis of gout was made by fine needle aspiration of tophus. FNAC of gouty tophus is an easy alternative to synovial biopsy. It is simpler, easier and less painful.

Fine needle aspiration cytology (FNAC) is a valuable diagnostic tool for the diagnosis of periarticular nodules. We present a case of forty five year old male with multiple soft tissue nodules on both the feet without any clinical and radiological features of arthritis. FNAC revealed needle shaped crystals consistent with monosodium urate crystals in amorphous granular debris. Diagnosis of gouty tophi was given. On follow up serum uric acid levels were found to be marginally high and a diagnosis of gout was established. FNAC is a valuable diagnostic tool for the diagnosis of periarticular nodules and pathologists should be aware of cytological features of gouty tophi.Keywords: FNAC, gouty tophi, monosodium urate crystals, uric acid Introduction:
