Hyperpigmented shiny sclerotic plaque over the chest of adult women

Abstract

A 50-year-old woman presented with a progressive, hyperpigmented plaque over the chest and upper portion of the abdomen developing over the past 6 months. She also complained of weight loss, anorexia, restricted movement of the chest, and dysphagia. Physical examination showed a hyperpigmented shiny sclerotic plaque involving the chest, extending to the bilateral axillary vault and upper abdomen and forming a circumferential sclerotic band (Fig 1). Laboratory test results were normal, including those pertaining to complete blood count and antinuclear, anti-centromere, anti-topoisomerase-1, and anti-RNA polymerase III antibodies.
