Generalized granuloma annulare. A report of a case and review of the literature

Multiple Annular Keloidal Plaques: A Clinical Case

“…In the literature, there are only rare anecdotal considerations of an association between GA and keloids. One review of 47 cases from 1967 found 3 patients with both entities [15]. An early GA case series from 1908 discusses 3 patients with lesions that clinically appeared as GA but histologically were determined to be keloid; the author hypothesized that there is a "keloid-like stage" in the involution of GA [16].…”

Long lasting interstitial generalized granuloma annulare on sun‐exposed areas

“…In 1967, Stankler et al . revised 47 cases of GGA . In five patients, the lesions were localized on sun‐exposed areas.…”

“…However, the role of ultraviolet light in the pathogenesis of GA is unclear. Results of monochromator light testing are usually negative when performed, photochemotherapy is a well‐described therapy for GGA and there are cases described that improved in summertime .…”
