The patients were cared for at a debarkation hospital for evacuees by air from the Pacific Theater. Patients were seen during the period from October 1944 to September 1945.In the first cases seen the condition was recognized as a new dermatologic entity, which showed some similarity to hypertrophic lichen planus. The violaceous papulosquamous lesions on the legs were clinically identical, and histologic sections were similar to a degree, although differing in the inflammatory reaction and intercellular edema. The large number of patients involved, the not infrequent deaths and the serious systemic involvement were entirely different. Polygonal shiny lesions characteristic of lichen planus did not occur.The disease is manifested by an eruption in which the essential lesion is papulosquamous, initially occurring as pinhead-sized SN - 0096-6029 M3 - doi: 10.1001/archderm.1947.01520040104011 UR - http://dx.doi.org/10.1001/archderm.1947.01520040104011 ER -
