| discoid l. erythematosus |
a chronic form of cutaneous lupus erythematosus in which the skin lesions mimic those of the systemic form but systemic signs are rare, although multisystem manifestations may develop after many years. It is characterized by discoid skin plaques showing varying degrees of edema, erythema, scaliness, follicular plugging, and skin atrophy surrounded by an elevated erythematous border typically involving the face and scalp, but widespread dissemination may occur. See also l. erythematosus profundus and hypertrophic l. erythematosus.

| discoid m. |
a semilunar lateral meniscus of the knee that has been transformed into a thickened, irregular discoid mass as a result of excess motion of the meniscus, which in turn results from congenital absence of attachment of the posterior horn of the meniscus to the tibial plateau. The excess motion also causes a clicking sound on flexion and extension of the knee. Occasionally, a discoid medial meniscus is observed. Called also congenital discoid meniscus.
