title: [Livid polycyclic plaques of the lower extremities].
abstract: In 10%-55% of patients, leukemia cutis (LC) manifest as a symptom of acute myelomonocytic leukemia and is associated with a poor overall prognosis. Disseminated bluish-violet or red-brownish papules and plaques, nodules and also hemorrhagic ulcers may dominate the initial clinical picture. Importantly, nonspecific infiltrates (leukemids) must be differentiated from specific infiltrates of malignant cells in patients presenting with dermatoses and concomitant underlying hematopoietic neoplasms. The role of the dermatologist is the rapid clinical and dermatohistopathological diagnosis in order to allow immediate, adequate treatment of the patient's underlying systemic disease.
