Description
Summary:Physical examination revealed a hyperchromic dark brown patch with irregular borders covered by dark coarse hairs extending from the left buttock up to the ankle joint, covering the posteromedial aspect of the left thigh and posterior aspect of the left leg [Figure 1]a, b and c. The lesion had a linear distribution following the lines of Blaschko. [1],[3] This abnormal phenotypic expression may be due to the somatic mutation occurring only in the affected segment of the body leading to linear pattern along with block configuration of some dermatoses.
