hereditary mucoepithelial dysplasia


Sunday 5 February 2006

Hereditary mucoepithelial dysplasia is a dominantly inherited disease, mainly characterized by chronic mucosal lesions associated with keratitis, non-scarring alopecia, keratosis pilaris and perineal intertrigo.

Since the original report by Witkop, this condition has been considered to be a disorder of desmosome/gap junction formation, but there has been no ex vivo investigation of these components using genetic and immunolabelling techniques.

Differential diagnosis

- chronic mucocutaneous candidiasis
- other follicular keratosis syndromes

  • ichthyosis follicularis-alopecia-photophobia (IFAP)
  • keratitis-ichthyosis-deafness (KID)
  • Siemens syndrome
