We herein report a case of gout, who was a 45-year-old man and had had multiple various-sized papules or tophi on the helices of ears, hands, elbows, knees, ankles and feet for 10 years. Histopathologic findings of the large tophus of right knee revealed the typical pattern of gout with needle-shaped urate crystal. The phenomenon of
iransepidermal elimination was observed in serial sections of histologic speeirnerls, The nsrrow transepidermal channel, lined by pseudoepitheliomstous lips bilaterally, was Eilled
with the cellular debris and urate crystal fragments and cornmunicated direotly with the upper dermis. Presumably, transepidermal elirnination in gouty tophus may be the phenomenon whieh could be found rnore commonly than the scarcity of literature. (Kor J Dermatol 28(1): 86-89, 1090)
