Leukaemic cell infiltration of the nose as a first manifestation of the disease is extremely rare. We report a case of a three year-old child who had presented with a swelling at the root of the nose for one month and proptosis of the right eye for one week. CT scan revealed a mass infiltrating the nose and nasal cavity along with infiltration of the retro-orbital region. Biopsy showed it to be myeloid cell deposits. Patient was put on antileukaemic chemotherapy but died two months after the first appearance of the symptoms.
