Annular elastolytic giant cell granuloma: response to cyclosporin A.

A case of annular elastolytic giant cell granuloma with a good response to cyclosporin A is reported. A 62-year-old man developed multiple annular patches on the trunk with elevated and indurated borders. Biopsy specimens from the border showed granulomatous inflammation in the mid dermis with phagocytosis of elastic fibers by giant cells. Biopsy specimens from the center showed dense collagen formation without inflammation. Immunological investigation of perivascular infiltrating cells in the lesions revealed a predominance of CD4+ cells over CD8+ cells. Our case showed a good response to cyclosporin A (5 mg/kg/day) for eight weeks. There were no adverse effects and no recurrences for one month after discontinuation of cyclosporin A.
