Leukocyte inhibitory factor (LIF) was investigated in 9 patients with localized granuloma annulare and 8 patients with the generalized form of the disease. The control group consisted of 10 matched, apparently healthy subjects. LIF values were significantly higher in patients with granuloma annulare of both groups than in controls (p less than 0.05 and 0.01). However, no significant difference was revealed between the two groups of patients. Though the results seem to speak for a cell-mediated immune response in granuloma annulare, they do not add a further support to the previously demonstrated differences between the two forms of granuloma annulare.
