Treatment of reticular erythematous mucinosis with a large dose of ultraviolet B radiation and steroid impregnated tape.

To date, there are no successful treatments for reticular erythematous mucinosis (REM) other than antimalarial drugs such as chloroquine; these have many adverse side effects and are prohibited for use in Japan. We report a case of REM improved by a large dose of ultraviolet B (UVB) radiation and a steroid impregnated tape. The large dose of UVB radiation improved the erythema after 5 weeks. Application of steroid impregnated tape to a lesion where a large dose of UVB had been given produced an additive clinical effect. UVB radiation and steroid impregnated tape are considered to be effective treatments for REM.
