Deafness occurs rarely in patients with chronic myeloid leukaemia. Hydroxyurea-induced leg ulcer has been found in patients on long-term hydroxyurea therapy. We present a 53 year old man who developed spontaneous bilateral deafness shortly after he was diagnosed with chronic myeloid leukaemia and subsequently developed hydroxyurea induced leg ulcer in the course of treatment. A 53 year-old male presented to our clinic with six months history of left abdominal mass, associated with easy satiety, occasional fever, night sweats, loss of appetite, weight loss, easy fatiguability and bilateral leg swelling. Physical examination showed a middle-aged man in no obvious distress, afebrile, anicteric, pale, with no peripheral lympadenopathy but had bilateral pitting pedal edema to the lower third. There was no significant finding on the chest. Abdominal examination showed hepatosplenomagaly. Full blood count showed anaemia, hyperleucocytosis and thrombocytosis. Peripheral blood film and bone marrow aspiration examinations were in keeping with chronic myeloid leukaemia. The BCR/ABL-1 transcript was negative, thus he was started on hydroxyurea in addition to other supportive treatment. Before commencement of hydroxyurea therapy, he spontaneously developed bilateral sensorineural deafness. Subsequently, he also developed leg ulcers, having been on hydroxyurea therapy for seven years which healed within eight weeks on discontinuation of hydroxyurea. Spontaneous deafness can occur in patients with chronic myeloid leukaemia due to hyperleucocytosis and urgent cytoreduction may help to prevent this complication. In addition, leg ulcer due to long-term hydroxyurea therapy can occur and usually do not respond to the conventional treatment but discontinuation of hydroxyurea.
