Gouty tophus presenting as a soft-tissue mass diagnosed by fine-needle aspiration: A case report

On the utility and limitations of fine-needle aspiration of palpable lesions located in the hand

“…The cytologic findings of gouty tophus have been described by Liu et al 19 and Nicol et al 20 Confirmation under polarization and compensated polarized microscopy is essential to reach a precise diagnosis and to rule out other entities containing polarizable crystals. 19 In an aspirate of a nodular mass located in the hand and containing metachromatic stroma, if calcium, osteoid, and cartilage can be safely ruled out, the diagnosis of gout should be entertained.…”

Tophaceous gout of the rotator cuff: A case report

“…The aspiration of unusual deposits, such as tophi, may also be performed for diagnostic microscopy. 9 The imaging of tophi is more variable than may be expected of calcium-containing deposits. Gerster et al 6 report on the use of computed tomography for intra-articular tophi of the knee, but outside of the knee, most reports comment on the use of MRI.…”
