Clinical InformationClinical

  • Erythema Induratum

    a type of panniculitis characterized 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.

  • Acrocyanosis

    persistent, symmetric, and painless blue discoloration of the extremities. it is the result of vasospasm in response to cold. the affected areas are cold and sweaty.

  • Neonatal Acrocyanosis

    transient cyanotic discoloration of the hands and feet, especially fingers and toes, in a newborn.
