Inflammatory myopathy in a patient with cutaneous findings of pityriasis rubra pilaris: a case of Wong's dermatomyositis.
We report the case of a 46-year-old woman presenting cutaneous lesions similar to those of pityriasis rubra pilaris, characterized by diffuse scaling erythroderma and palmoplantar keratoderma; skin biopsy showed follicular hyperkeratosis with a perivascular lymphocytic infiltrate. One year later she developed an inflammatory myopathy; on the basis of clinical features, a diagnosis of dermatomyositis was made. Treatment with prednisone and hydroxychloroquine led to complete control of the cutaneous and muscular involvement, which was maintained during prednisone tapering.
