Three cases of cardiac sarcoidosis clinically mimicked arrhythmogenic right ventricular dysplasia or cardiomyopathy until a pathology diagnosis was made at biopsy or autopsy.
Case Report (n=3)
Cardiac sarcoidosis can clinically mimic ARVD/ARVC, making pathological diagnosis crucial since sarcoidosis may respond to corticosteroid therapy.

Consider sarcoidosis in ARVC-like cases needing pathology; case reports leave open steroid impact on outcomes.
Patients with cardiac sarcoidosis may present with clinical and morphological features similar to arrhythmogenic right ventricular dysplasia (ARVD) or cardiomyopathy (ARVC). Three cases of cardiac sarcoidosis are presented that clinically mimicked ARVD or ARVC until a pathology diagnosis of sarcoidosis was made at biopsy or autopsy. A diagnostic distinction, while often difficult to make, is important since treatment with corticosteroids may benefit those with sarcoidosis but is not expected to be useful in cases with ARVD or ARVC.
