Nonisomorphic and nonisotopic multidermatomal discoid lupus erythematosus – A rare subtype of cutaneous lupus erythematosus

摘要

Discoid lupus erythematosus (DLE) is the most common variant of chronic cutaneous lupus erythematosus. Several cases of Blaschko-linear lupus erythematosus, which is regarded as a distinct subtype of lupus erythematosus, have been reported across the globe. Dermatomal involvement in DLE is rare and that too has been reported in patients of systemic lupus erythematosus at site of healed herpes zoster either as an isomorphic or isotopic phenomenon. Here, we report a case of DLE on account of its unusual morphology, de novo multidermatomal configuration, without previous episode of herpes zoster or trauma.
