Dermatomyositis with follicular hyperkeratosis.
We report 2 cases of dermatomyositis with follicular hyperkeratosis (FHK) in children. They occurred in a 10-year-old Vietnamese girl and a 9-year-old Caucasian boy. The girl's FHK disappeared after 2 months of treatment. The boy presented, 15 months after the onset of his dermatomyositis, with a generalised FHK which lasted for 6 months. FHK can appear before, during or after dermatomyositis. It is more often generalized but can be localised. Erector pili myositis and ostial hyperkeratosis may be the explanation. The prognostic value of FHK in dermatomyositis is unknown. This manifestation, initially considered to be more frequent in the Far East, is not as rare in Western countries as the few reported cases suggest.
