AbstractNodular scleroderma is a rare variant of systemic sclerosis (SSc) characterized by fleshy, indurated nodules commonly distributed over the upper and lower extremities and in the trunk. Most scientific publications of the nodular and keloid variants of scleroderma use the terms interchangeably. However, nodular scleroderma has been recently differentiated from keloid forms. Although few cases of isolated local involvement have been reported, nodular scleroderma more commonly presents in conjunction with other manifestations of SSc. We performed a review of all cases of nodular scleroderma reported in the literature to characterize their clinical features. This review indicated that Nodular Scleroderma is usually associated with a Diffuse SSc phenotype and develops during the early progressive skin involvement. Patients with the Nodular Scleroderma phenotype display antinuclear antibodies with speckled or nucleolar patterns, a low frequency of positive SSc-specific antibodies, and typical SSc multiorgan involvement. However, a very low frequency of pulmonary hypertension was found in these patients. Although immunosuppressive or antifibrotic treatment may improve skin thickening and organ involvement, the characteristic nodules are refractory to treatment with these agents. This is the first review, to our knowledge, characterizing the nodular phenotype in patients with SSc.Copyright © 2024. Published by Elsevier Inc.
