Partial Albinism

Erythroblast
  • CDA type II, also known as hereditary erythroblastic multinuclearity with a positive acidified serum test (HEMPAS), is the most frequent one.[ncbi.nlm.nih.gov]

Treatment

  • According to the patients, final repigmentation was achieved after a mean of 10 months post-treatment.[ncbi.nlm.nih.gov]
  • BACKGROUND: Several surgical techniques have been proposed for the treatment of piebaldism. These procedures, however, are poorly suited for the treatment of large leucodermal lesions, can cause scars and require multiple donor sites.[ncbi.nlm.nih.gov]
  • BACKGROUND: Autologous noncultured cell suspension transplantation is an effective treatment for repigmentation in segmental vitiligo and piebaldism.[ncbi.nlm.nih.gov]
  • Piebaldism is a rare genodermatosis in which depigmented skin areas are unresponsive to topical or light treatment.[ncbi.nlm.nih.gov]
  • After the transplantation, UV-treatment according to the standard treatment protocol of the NIPD will be started on all sites and continued for 3 months.[clinicaltrials.gov]

Prognosis

  • […] hairbulbs in the white patches of hair; occasionally, individuals lack ganglion cells of the intestinal enteric neural plexus, which like melanoblasts, are derived from the neural crest Neoplastic risk an increased risk of epithelioma has been reported Prognosis[AtlasGeneticsOncology.org]
