Description
Summary:Discoid lupus erythematosus (DLE), a subtype of chronic cutaneous lupus may be observed in a linear pattern. A 21-year-old woman with history of chronic granulomatous disease state presented to our clinic for a chronic six-year skin eruption on her left eyebrow, left cheek, and left forehead. A punch biopsy of involved left forehead skin was performed and revealed perivascular and periadnexal lymphohistiocytic infiltrate without features of morphea or panniculitis, confirming the histopathologic changes of cutaneous lupus erythematous. The patient was diagnosed with linear DLE, mimicking en coup de sabre, within Blaschko lines. The pathogenesis for DLE in association with chronic granulomatous disease is ambiguous; however, X-linked lyonization is crucial for both conditions and may explain cooccurrence of disease states.
