  • Title: Palisading granuloma presenting in a patient with systemic lupus erythematosus.
    Author: Ohtsuka T.
    Journal: J Dermatol; 2008 Jul; 35(7):452-5. PubMed ID: 18705834.
    Abstract:
    A patient with systemic lupus erythematosus who developed a distinctive nodular eruption demonstrating typical features of palisading granuloma is presented herein. A 60-year-old woman was admitted complaining of an elastic-hard, indurated nodule on the right dorsal aspect of the metacarpophalangeal joint of her third finger with a history of several years. She was successfully treated for her lupus nephritis with oral predonisolone. She had experienced erythema on her cheeks after sun exposure and polyarthralgia for a decade. Laboratory examination revealed positive results for antinuclear antibody and rheumatoid factor. Peripheral blood cell counts showed leukocytopenia and lymphocytopenia. Results of hand X-ray were unremarkable. Histological examination of the skin biopsy specimen from the nodule revealed a structure composed of a central area of fibrinoid necrosis, surrounded by a middle zone of palisading cells and an outer zone of chronic lymphocyte infiltrate. These findings led us to the histological diagnosis of palisading granuloma. She was diagnosed as having systemic lupus erythematosus complicated with a rheumatoid nodule. She is currently under treatment with cyclophosphamide (50 mg/day) without exaggeration of her systemic lupus erythematosus and nodule.
