A new eruption of bullous pemphigoid within psoriatic plaques following cyclosporine withdrawal

Concurrent bullous pemphigoid and plaque psoriasis successfully treated with Janus kinase inhibitor Baricitinib

“…Bullous pemphigoid (BP) is a rare, life-threatening autoimmune bullous disease (AIBD) involving autoantibody formation against the basement membrane zone (BMZ). 1,2 Recent meta-analysis of this disease showed a global incidence of 0.1138 per 10,000 person-years. 3 Although the pathogenesis of BP remains obscure, BP can co-occur with other immune-related diseases such as psoriasis and lichen planus.…”

Successful Treatment of Psoriasis Combined with Bullous Pemphigoid with Dupilumab: A Case Report

“…Iskandarli et al 5 reported a case of BP after a sudden interruption of treatment in pustular psoriasis and suggested that the presence of BP is a sign of active inflammation in psoriasis. BP is often triggered by anti-psoriatic drugs, such as cyclosporine, 6 etanercept, 7 adalimumab, 8 stelara, 9 and secukinumab. 10 In addition, Minakawa et al 11 reported a case of dipeptidyl peptidase-4 inhibitor-induced anti-laminin γ1-like pemphigoid in a diabetic patient with psoriasis, and Saraceno et al 12 reported BP occurs following the use of losartan for hypertension in a psoriasis patient, but the patient received UVB therapy before the onset of bullae.…”
