title: Eruptive keloids: spontaneous reactivation after 60 years.
abstract: An 84-year-old man with keloids since early adulthood, was referred to our clinic because of the recent appearance of erythematous, tumid plaques upon the old keloids and upon uninvolved skin. The plaques were located mainly on the trunk in a linear distribution. On the back there were round, nodular, erythematous nodules and plaques, with central crusts, that had just appeared on normal skin. A skin biopsy was performed on the plaques that appeared over the older lesions. The histological appearance was consistent with keloid. Similar histology was found in a biopsy taken from a plaque that had erupted on normal skin.
