Certain skin diseases are accompanied by a vascular dysfunction in areas which are remote from the sites of visible lesions. This abnormality has been demonstrated by changes in the forms of photoelectric plethysmograms of the fingers of patients with lupus erythematosus1 and psoriasis2 which are similar to those found in arteriosclerosis,3 hypertension,3 and pseudoxanthoma elasticum.4
It is the purpose of this report to present the results of photoelectric plethysmograms of patients with various dermatoses.
MATERIAL AND METHODS
Studies were made on 28 normal subjects and on 16 patients with various types of lupus erythematosus, 7 with scleroderma (1 linear and 4 localized), 11 with psoriasis, 12 with atopic dermatitis, and 15 with miscellaneous dermatoses, including dermatitis herpetiformis, eczema, dermatomyositis, pemphigus, contact dermatitis, seborrheic dermatitis, neurotic excoriations, lichen planus, erythema multiforme, and tuberculid.
