Clinical presentation

In case 1, a 36-year-old man presented with a 4-year history of pitted, keratotic lesions on the soles (Fig 1, A) and asymptomatic papules on the upper aspect of his left arm for 1 year (Fig 1, B). In case 2, a 25-year-old man presented with asymptomatic papules scattered over his trunk of 1.5-year duration and a 6-month history of slowly enlarging eruptions on the palms (Fig 2). All study methods and protocols were approved by the institutional review board of Zhongnan Hospital of Wuhan

Dermoscopic examination

The dermoscopic findings are shown in Fig 3.

Histologic diagnosis

The histopathologic diagnoses for lesions from nonpalmoplantar and plantar areas were lichen nitidus (Fig 4).

Key message

Lichen nitidus is characterized by multiple, small, discrete, shiny, flesh-colored, dome-shaped papules usually arranged in groups on the trunk and genitalia. Other sites such as palms and soles are seldom involved.1, 2 As a rare condition, palmoplantar lichen nitidus may only occur on the palms and/or soles, or accompany lichen nitidus lesions at other locations.
