Eruptive Keratoacanthomas

Keratoacanthomas are low-grade malignant skin tumors that are known to arise over sites of trauma. Although previously described in association with ablative laser treatment of the face,36 the development of multiple eruptive keratoacanthomas after fractional resurfacing has more recently been reported on the legs of two patients.37 Of note in the latest report is that both patients had a history of actinic keratoses in the treatment sites preoperatively. Four to 6 weeks after treatment, hyperkeratotic papules appeared in their place that were histologically proven to be keratoacanthomas. The authors speculated that trauma to the follicular unit during fractional laser treatment could have induced these low-grade tumors.37 This report reemphasizes that physicians should exercise caution when treating extensive and hypertrophic actinic keratoses on legs with fractional laser resurfacing.
