Other papers report neutrophilic dermatosis, bullous pemphigoid, pemphigus, vasculitis, Gianotti-Crosti syndrome, dermatomyositis and lichen planus (table 1) [4,5,7,8,9,10,11,12,14,15,16,17,18,19,20,21,22]. Tsushima et al [14] reported a case of an erythema-nodosum-like eruption appearing 7 days after an influenza vaccination.…”
