Granuloma Annulare. Presented by Dr. Meyer L. Niedelman.
M. D., a white man aged 50, of good general appearance, three years ago noted a lesion on the inner proximal area of the right index finger. It was treated with roentgen rays and now appears as a circumscribed area of erythema with atrophy in the center. There is a suggestion of roentgen ray dermatitis. The present lesion began nine months ago and is situated on the inner dorsal surface of the right hand. It is annular and measures 3.5 cm. in diameter. The central area is free, and the surrounding border is elevated and infiltrated; the border is studded with fine, discrete, pinkish papules. There is a similar, smaller lesion on the left index finger. There are no subjective symptoms.The patient has had diabetes for six years. The blood sugar level on October 1 was 186 mg. per hundred cubic
