Lichen Obtusus Corneus. Presented by Dr. Bragg.
A woman, aged 36, a domestic, had a negative and personal family history. Her general health had been very good. Sixteen years before presentation she had noticed a few papules or vesicles on the forearms. The number had gradually increased, now extending over most of the extensor surface of the upper arm and forearm (most of them appearing as papules). About nine or ten years ago the eruption appeared on the lower extremities, and it now involves the entire surface of the legs and the outer aspect of the thighs and buttocks. There are some lesions across the shoulders, and in recent weeks some have appeared on the face. These lesions are entirely free from pain, but are extremely uncomfortable on account of the intense itching day and night. This symptom has been constant from the very first. The progress has been gradual
