[Annular granuloma in HIV positive patients].
Pathogenesis of Granuloma Annulare is not resolved. In some Authors' opinion it is caused by an allergic granulomatous reaction to an unknown dermal antigen. Presence of Granuloma Annulare in patients with Human Immunodeficiency Virus (HIV) infection questions this hypothesis. We present two cases of such association and review eleven patients previously described in the literature. Clinical and histological findings suggest that the cell mediate immune response is not the dominant pathogenetic event, especially in cases of altered cell-mediated immunity.
