A 74‐year‐old Vietnamese man presented with a 1‐year history of pruritic nodules on his feet. There was no history of gastrointestinal cancer or hereditary palmoplantar keratoderma. Examination found bilateral, focal, palmoplantar keratoses of the soles (~ 6 × 8 cm), with mild palmar involvement (~ 1 × 1.5 cm) (Figure). The differential diagnoses were psoriasis, lichen planus and verrucae vulgaris, but there were no other clinical features consistent with these conditions.
