Fine-needle aspiration cytology of periarticular nodule – Atypical presentation of gouty tophi: A report of two cases

Gout is a chronic arthropathy caused due to the deposition of monosodium urate crystals. Gouty tophus can be the initial presenting feature of gout with or without any clinical symptoms. Demonstration of urate crystals in synovial fluid or biopsy helps in confirming the diagnosis of gout. However, fine-needle aspiration cytology (FNAC) of periarticular soft-tissue nodules is a valuable tool in the diagnosis of gout. We present two such cases of isolated soft-tissue lesions wherein the initial diagnosis of gouty tophus was made on FNAC and subsequently followed by a clinical and biochemical workup.
