[Actinic granuloma. Presentation of 3 cases]

Three cases of actinic granuloma which presented anular lesions with central atrophy in the frontotemporal region are reviewed. Microscopy changes showed the center of the lesion devoid of elastic fibers, an inflammatory reaction at the edge of the lesion and normal elastic fibers in the surrounding area. We discuss the differential diagnosis with granuloma annulare and the possible etiological role of previous actinic damage.
