REPORT OF A CASE
A 61-year-old man presented for follow-up of actinically damaged skin. Additionally, he exhibited a series of linear bands across his back. The asymptomatic bands
had been present since age 19 and had changed little since then. The patient was otherwise healthy and had a normal serum lipid profile. He gave no history of previous trauma to the involved area, no rapid weight gain or loss, and no systemic or topical steroid use.
Physical examination revealed multiple 2- to 3-mm palpable elevated yellowish linear bands that extended horizontally across the midline of his lumbar area (Figure 1). There was no involvement of other regions of his body.
A representative biopsy specimen was obtained from one of the hands. Pathologic sections are shown in Figure 2 and Figure 3.
