Generalized perforating granuloma annulare is characterized by 1 to 4 mm umbilicated papules on the extremities, and is most commonly seen in children and young adults.

Perforating sarcoidosis and perforating granuloma annulare may be difficult to differentiate because of a similar clinical appearance and the presence of sarcoidal granulomas in biopsy specimens. A particularly high incidence of perforating granuloma annulare has been reported in the Hawaiian Islands.
