Increased level of circulating gamma/delta T cells in a patient with eosinophilic granuloma.
A patient with eosinophilic granuloma, histologically confirmed from open lung biopsy specimen, had a history of scarlet fever and a prominently high level of circulating gamma/delta T cells (25 percent) in comparison with normal levels (< 10 percent). Despite steroid therapy, the levels were persistently high. To our knowledge, this is the first report of an increased level of circulating gamma/delta T cells in a patient with eosinophilic granuloma.
