Reporte de un caso: presentación cutánea de leucemia B madura en un paciente pediátrico e inmunocompetente

We report the case of a 14-year-old male, native of La Pampa, previously healthy and immunocompetent. He is admitted due to fever, headache and vomiting. Physical examination shows subcutaneous nodules on the scalp. A complete blood count stops a lumbar puncture. Peripheral blood smear makes it possible to suspect the diagnosis confirmed by bone marrow puncture and skin biopsy.
