A Case of Chronic Myelomonocytic Leukemia With Recurrent Skin Involvement.

Chronic myelomonocytic leukemia is a clonal hematopoietic stem cell disorder with both myelodysplastic and myeloproliferative features, leading to a variable clinical presentation. Some types of skin involvement, such as leukemia cutis and blastic plasmacytoid dendritic cell neoplasia, are associated with poor prognosis. This case study describes a 71-year-old male with high-risk CMML, developing pink-purple skin nodules, which regressed with azacitidine and hydroxyurea treatment. Despite recurrence, disease control was achieved without transformation to acute leukemia. This case highlights the need for vigilant monitoring and adaptable treatment strategies in managing CMML with skin involvement.
