A Case for Diagnosis (LichenPlanus). Presented by Dr.John E. Lane.
J. A., a man, aged 33, presented a generalized, slightly scaly erythroderma of two months' duration. A few clear pea-sized vesicles had appeared occasionally. The inguinal, axillary and cervical glands were moderately enlarged. The blood count was normal, and the Wassermann reaction was negative. There was some lichenification but no papules typical of lichen planus.
Dr. E. F. Traub: The patient presented definite lichenified papules on the penis, and scattered throughout the entire eruption there seemed to be characteristic lichen-like papules. Owing to the scratching, this condition might be interpreted as lichenification, but some of the papules seemed to be entirely independent of the lines of cleavage of the skin; a distinct violaceous color with the suggestion of milky striation was also present. I should think that lichen planus would have to be ruled out.
