To the Editor.—
We have read with great interest the article in the Archives by Gottlieb et al (108:551-553, 1973) concerning a case of focal dermal hypoplasia.The descriptions of clinical and roentgenographic findings are very detailed. We have some doubts, however, about the interpretation of the metaphysial bone texture. The authors have observed a modification that they attribute to osteoporosis.After examination of nine focal dermal hypoplasias, we have noted the presence of a striated osteopathy in all female cases. Striated osteopathy may be defined as a particular osteocondensation made up of fine, opaque, parallel vertical bands. These bands spread from the juxtaepiphysial part through the metaphysis, where they are broader, to the juxtametaphysial part of the diaphysis, where they grow thinner and fade off. This striated osteopathy is bilateral and symmetrical; it involves the metaphysis of the long bones.These conclusions were first published by Larregue et al
