An African Kenyan female infant was born with very light skin and ashen grey, scanty hair. At 18 months she presented with a bluish skin pigmentation, hepatosplenomegaly, generalised lymphadenopathy and non-responsive fever. A bone marrow aspirate and peripheral blood examination done revealed characteri¬stic features of the Chediak-Higashi Syndrome. This is a rare disorder, to our knowledge not previously described in Africans. The case is presented with a brief review of the literature

This is a retrospective study of 105 patients with herediatry haemorrhagic disorders seen at the Kenyatta National Hospital (KNH), between March 1975 and July 1980. Haemophilia forms 63% of the cases, Christmas disease 22% and von Willebrarid's disease (VWD) 9.5%. Rarer disorders encountered are factors X and VIII deficiency and one case of Glauzmann's disease. The study includes 3 subjects of Asian descent. Haernophilia co-existed witlt B-thalassaemia trait in 2 of the Asian subjects. Co-existing Christmas disease' and sickle cell anaemia was seen in one case. The clinical picture and course ' of the disorders are very similar to what is described elsewhere in the literature. It is. noted that although complications of replacement therapy in bleeding disorders are well documented elsewhere, only one of these patients' showed clinical evidence of such complications. There is now ample evidence that haemophilia is quite common in Africans, contrary to some reports in the past. This report serves as further evidence that haemophilia is not uncommon in Kenya and adds on to the already documented cases of hereditary haemorrhagic diseases in Kenya (1). With improving diagnostic and therapeutic facilities and increased use of hospital services more of these cases will be diagnosed
