To the Editor.—
I am constantly astonished by what one can learn by reading journals. Last week I was called to the bedside of a middle-aged woman with typical myositis complete with elevated enzyme levels. The consulting internist, Dr. Jason Lucas of Lexington, Mass, asked me if I could find cutaneous confirmation of the diagnosis of dermatomyositis.After a diligent search, I reported with regret that I could detect only longitudinal striate yellow fingernails and toenails and a dry scaling of the cuticle bed, such as the one I myself have had in the winter. I pointed out that these changes are seen in psoriasis on occasion as well as in Reiter syndrome. Some cases of dermatomyositis are preceded by psoriasiform eruptions. I have attended patients who developed a generalized erythroderma, one of whom developed hypothermic coma.1Having read with great enjoyment Dr. Samitz's article in the Archives,2
