[Dermo-neuro-hypsarrhythmia. Association of a congenital dermatosis and hypsarthymia. 9 cases (author's transl)].

These 9 cases confirm that tuberose sclerosis, von Recklinghausen's neurofibromatosis, incontinentia pigmenti, linear warty sebaceous naevus and alopecic naevus resulting in a woolly naevus of the scalp may be complicated by flexion spasms with hypsarhythmia. Early diagnosis of hypsarhythmia makes possible specific treatment with ACTH or hydrocortisone.
