Case for Diagnosis.

Abstract

THE patient, a young woman, aged 33, of healthy appearance, had a peculiar condition of the extremities which began about six years ago on the palms of the hands and soles of the feet, where it remained limited for nearly two years. Since then it gradually extended up to the middle of the forearms and legs, being fairly well demarcated from the sound skin. It was of a brownish colour, and the numerous lines which intersected one another, as well as the roughness that was present, gave it the appearance of crocodile leather. There was, however, no appreciable thickening, no evidence of the follicles being involved, and no itching. Besides this condition there were patches of a psoriatic-looking eruption on the patelle and elbows. The eruption, which had never been m-ioist and was of a remarkably uniform appearance, did not appear to correspond to any described condition.
