Most cases had a flat epidermis with loss of the rete pattern and a thickened orthokeratotic basket weave stratum corneum. The epidermis had markedly decreased to absent melanin in the basal layer and reduced numbers of melanocytes at the dermoepidermal junction. One-third of patients had a sparse perivascular lymphocytic infiltrate, whereas the rest had no significant dermal inflammation. These findings are in concordance with current literature. However, small foci of retained melanin in the basal layer (skip areas) alternating with larger areas of melanin loss were present in almost 80% of cases. This finding has not been reported earlier and appears to be quite specific to IGH and may be used as a clue to differentiate IGH from other similar conditions such as vitiligo and guttate morphea.<\/jats:p>","DOI":"10.4103\/0019-5154.143516","type":"journal-article","created":{"date-parts":[[2014,10,29]],"date-time":"2014-10-29T03:05:15Z","timestamp":1414551915000},"page":"571-574","update-policy":"https:\/\/doi.org\/10.1097\/lww.0000000000001000","source":"Crossref","is-referenced-by-count":16,"title":["Skip Areas of Retained Melanin: A Clue to the Histopathological Diagnosis of Idiopathic Guttate Hypomelanosis"],"prefix":"10.4103","volume":"59","author":[{"given":"Rajiv","family":"Joshi","sequence":"first","affiliation":[{"name":"Department of Dermatology, P.
