Abstract
BACKGROUND
Hypohidrotic ectodermal dysplasia (HED) is a rare multisystem disorder that typically affects hair, teeth, nails, and sweat glands in combination with abnormalities of ectodermal originated tissues.
OBJECTIVE
To raise the issue of whether heightened awareness is required in the follow-up of pigmented lesions in patients with HED.
METHODS/RESULTS
Two patients with HED are reported. The first had a history of two malignant melanomas, whereas the second presented with a novel malignant melanoma.
CONCLUSION
Although a prospective epidemiologic study to determine the incidence of malignant melanoma in patients with HED is virtually impossible and the probable pathogenesis warrants further investigation, these two case reports, in conjunction with other recent reports associating other ectodermal dysplasias with malignant melanoma, suggest that heightened awareness might be prudent in the follow-up of pigmented lesions in patients with HED.
