Abstract:
Granuloma annulare (GA) and cutaneous sarcoidosis show clinicopathological overlap and they are also aetiopathogenically related. Given the similarities of sarcoidal GA and sarcoidosis, and the reports of association of sarcoidal GA with systemic sarcoidosis, this diagnosis should prompt further investigation to exclude systemic involvement. Being aware of the subtle histopathological clues is of the utmost importance for an accurate diagnosis of this rare variant, but correlation with the clinical setting and use of ancillary investigations are also warranted to confidently exclude sarcoidosis.
