Wartlike Lump in a Chinese Woman With Bound Feet

An 83-year-old Chinese woman presented to our clinic with bound feet. One month prior to presentation she noticed a plaque in the fold of her right foot that had gradually developed without any sensation. The lesion had occasionally bled. A medical history revealed that she had experienced an episode of cerebral thrombosis 5 years prior to presentation and had recovered without serious sequelae; otherwise, she generally was in good health. Physical examination revealed a plaque located at the flexor side of the third toe on her right foot. The plaque measured 1.5×1.5 cm and was flesh colored with a warty and erosive surface. In addition, her feet gave off a foul odor. Her feet had been bound during childhood. Physical examination revealed no other abnormalities. An acetowhitening test was negative. A wart was highly suspected, though the woman declined biopsy or other laboratory testing. Antiseptic solution was prescribed to prevent secondary infection. She was closely followed up weekly with telephone calls. Four weeks later she reported that the lump spontaneously disappeared.
