He had a 6 by 9 cm ulcer on the anterior aspect of the left leg (Figure 1(a)) and bilateral brownish atrophic plaques on the pretibial areas mimicking necrobiosis lipoidica (Figure 1(b)). His skin was thin with visible venous pattern on the trunk (Figure 1(c)). Four atrophic scars were noted on his right knee and both thighs (Figure 1(d)). He had periodontitis with apical root resorption and gingival recession (Figure 1(e)).
