A patient with onychotrichodysplasia, neutropenia and normal intelligence.

A 9-year-old boy with onychotrichodysplasia and chronic neutropenia is presented. In contrast to cases described earlier, our patient has normal intelligence. The typical features of trichorrhexis nodosa are shown by electronmicroscopic photography. The chronic neutropenia is discussed and supposed to be part of the so-called lazy leucocyte syndrome.
