Erythema annulare centrifugum in a case of chronic myeloid leukemia

Abstract

Chronic myeloid leukemia (CML), BCR-ABL1-positive, is classified as a myeloproliferative neoplasm predominantly composed of proliferating granulocytes and determined to have the Philadelphia chromosome/translocation t (9;22)(q34;q11.2). Skin is said to be the mirror to systemic diseases, with skin manifestations ranging from nonspecific cutaneous lesions to specific lesions. The cutaneous manifestations of CML are generally reddish-brown to violaceous papules and nodules, indurated or hemorrhagic plaques, perifollicular acneiform papules, bullae, and palpable purpura. Other unusual manifestations could be erythema nodosum, pyoderma gangrenosum, erythema annulare centrifugum, and so on. Here we present a case of a 50-year-old woman with a history of recurrent pruritic skin lesions and erythema annulare centrifugum as the presenting complaint of CML.
