The study analyzed the features of scar sarcoidosis (SS) in patients with systemic sarcoidosis at Bellvitge University Hospital from 1980 to 2017.
Out of 728 systemic sarcoidosis patients, 42 (5.77%) exhibited SS, with most cases appearing at disease onset and some associated with erythema nodosum.
The findings suggest that while SS can indicate sarcoidosis, it does not significantly impact the prognosis of the disease.
