To the Editor.—
The term ectodermal dysplasia (ED) describes a group of inherited, nonprogressive disorders affecting skin and structures derived from embryonic ectoderm1 (primarily hair, teeth, nails, and sweat glands).Cape Verde is a cluster of islands in the Atlantic Ocean. Two immigrant families from Cape Verde are described with a newly defined form of ED.
Report of Cases.—Case 1.—
A 10-year-old girl had white spots on her skin for several years. She was otherwise healthy and active. One brother (out of nine siblings) reportedly had similar lesions.The examination revealed a child of normal size and intelligence for her age. Skin turgor and texture were normal, but there were multiple 2- to 5-mm depigmented macules on her extremities (Fig 1). The frontal hairline was considerably displaced toward the posterior aspect; the density was otherwise normal, and no shaft anomalies were appreciated on a hair mount examination.
