[Pili anulati].
Report on a 10 year-old girl with pili anulati. Clinical and microscopical findings of that maldevelopment of hair are described. Interestingly, an episodical alopecia totalis and subsequent regrow exhibiting different hair color was observable. Genealogical search confirmed autosomal dominant genetics. The question of expressivity of that dominant gen is discussed.
