Livedoid eruption in a patient affected by T-{gamma}{delta} large granular lymphocyte leukaemia

Livedo is an ischaemic dermopathy characterised by a reddish-blue to violaceous mottling of the skin with a net-like reticular appearance. Livedo has been described in association with several medical conditions including lymphoproliferative disorders. Here, we describe the case of a 60-year-old woman who was presented with asymptomatic and persistent livedoid eruption on her trunk, lower and upper extremities as manifestation of an indolent form of T- large granular lymphocyte leukaemia. To the best of our knowledge, this is the first report describing the association between livedo reticularis and T- large granular lymphocyte leukaemia. It is plausible that a pathogenetic role of the neoplastic process is based on a cytotoxic antiendothelial activity.
