| erythema induratum | A type of panniculitis characterised histologically by the presence of granulomas, vasculitis, and necrosis. It is traditionally considered to be the tuberculous counterpart of nodular vasculitis, but is now known to occur without tuberculous precedent. It is seen most commonly in adolescent and menopausal women, is initiated or exacerbated by cold weather, and typically presents as one or more recurrent erythrocyanotic nodules or plaques on the calves. The nodules may progress to form indurations, ulcerations, and scars. (12 Dec 1998) |

After 1-2 days the rash will often spread to the extremities and trunk. The illness is nonserious and self-limiting. Environmental factors such as sunlight, hot baths and emotional factors can cause the rash to recur. Referred to as fifth disease or erythema infectiosum. (27 Sep 1997) |
