Abstract
- Interestingly, comparison of the histopathologic findings of the annular EO lesions in patients with and without systemic sarcoidosis showed only minor differences.5 In patients with systemic sarcoidosis, the zonal pattern on histopathology was less defined. Only 1 patient had skin lesions outside of the area of EO, but it was not reported whether this patient had systemic sarcoidosis or cutaneous lesions only.

AG-like change in EO has been reported in a patient who presented with annular lesions on a background of severe EO.7 Of note, in AG, elastophagocytosis is a prominent feature, which is absent in actinic granuloma-like EO.
