The Argon Laser for Cutaneous Lesions

JAMA. 1982;247(1):29. doi:10.1001/jama.1982.03320260017018

To the Editor.—  The review article entitled "The Argon Laser for Cutaneous Lesions" by Apfelburg et al (1981;245:2073) was most timely. However, one might question the practicality of treating seborrheic keratoses with the argon laser. After all, these "stuck-on" nevoid excrescences are typically amenable to superficial curettage.Moreover, the authors' description of granuloma faciale as a "nonspecific dermal inflammatory fibrosis" is incorrect. Clinically, this lesion appears as an enlarging, brownish-red plaque of the face that may occasionally manifest follicular dilation. The histopathological pattern is characteristic.1 Salient features include the presence of a Grenz zone, polymorphous inflammatory infiltrate consisting of histiocytes, lymphocytes, plasma cells, and eosinophils with evidence of leukocytoclasia, and connective tissue trabeculations adjacent to the dermal blood vessels. Therefore, granuloma faciale is a type of leukocytoclastic vasculitis and quite the antithesis of a "nonspecific" dermatopathic entity.
