Bioresorbable vascular scaffold to treat malignant in-stent restenosis in a patient with nickel allergy

Nickel is the most frequent allergen in patients with allergic contact dermatitis and nickel allergy has been associated with recurrent in-stent restenosis. However, it is often misdiagnosed because of a low suspicion threshold. It should be discarded in patients with recurrent in-stent restenosis, specially if their medical history reveals prior contact dermatitis. It is also noteworthy and rarely specified that, even newer generation stents that use novel metal alloys also contain low amounts of nickel.
