A single subcutaneous injection of Oriental hornet venom into black mice led to the development of a subcutaneous nodule which showed no change during the period of 1 year. Study of the ultrastructure revealed an accumulation of lymphocytes and lymphoblasts and a few plasma cells with formation of Russel bodies. In addition, a few melanin-containing macrophages and macrophages filled with cellular debris were found. This reaction is compared to other pseudolymphomatous reactions in the dermis.
