Recurrent annular erythema in juvenile chronic myelogenous leukaemia.

Abstract

Juvenile chronic myelogenous leukaemia (JCML) is a rare haematological malignancy of myelomonocytic lineage that affects patients less than 4 years of age and is known as an entity different from adult-type chronic myelogenous leukaemia. In JCML, skin manifestations are relatively common but most of them have been reported as a non-specific eruption, which histologically may show changes resembling neurofibromatosis or xanthogranuloma. We present a 2-year-old boy with JCML who developed a recurrent annular erythema in which leukaemic infiltrates were confirmed histologically, even though his bone marrow examination suggested that be remained in haematological remission.
