[Generalized perforating folliculitis in chronic kidney insufficiency].

A 24-year-old female patient is reported, in whom severe renal insufficiency following renal transplantation for Goodpasture's syndrome was associated with a persistent generalized perforating folliculitis of the trunk and extremities. In addition to the pathologic renal parameters a hypervitaminosis A was found. On the basis of this observation as well as similar recent reports in the literature it is suggested that a subset of an unusually extensive perforating folliculitis may occur with renal insufficiency and, albeit rare, represents a clinical marker for this associated condition.
