Explanation: I think there is printing mistake in this question. There should be except in this question. In that case answer will be erythema induratum.
Neonatal fat necrosis, post-steroidal panniculitis, Lipodermatosclerosis and lupus panniculitis belong to same group, i.e. Mostly lobular panniculitis without vasculitis.
Erythema induratum belongs to other class, i.e. Mostly lobular panniculitis with vasculitis.
