A 50-year-old woman presented with an 18-month history of asymptomatic skin lesions on her forehead (Panel A) and the dorsum of her hands (Panels B and C). The lesions were well-demarcated, erythematous, coalescing annular plaques with raised borders and slightly atrophic centers. Over time, the lesions gradually increased in number and slowly extended centrifugally. A skin biopsy showed a lymphohistiocytic infiltrate with multinucleated giant cells and surrounding solar elastosis, without apparent palisading, necrobiosis, or mucin deposition.
Fragmentation of the elastic fibers and occasional elastophagocytosis by giant cells in the granulomatous area were noted. What are these lesions? What could be the diagnosis? Source: The New England Journal Of Medicine *This case is from Docplexus editorial team for educative purpose only
