title: Nail Sarcoidosis with and without Systemic Involvement: Report of Two Cases.
abstract: The most commonly seen nail change in sarcoidosis, often associated with chronic systemic disease, is onychodystrophy. Imaging of hands, feet and chest is of paramount importance when nail sarcoidosis is suspected, for evaluation of bone cysts and pulmonary involvement, respectively. We report 2 cases of sarcoidosis that developed nail involvement - one with pulmonary disease, and the other without any evidence of systemic involvement, which is very rare.
