Chédiak-Higashi syndrome: a case report on an African infant.

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 characteristic features of the Chédiak-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.

The role of needle aspiration cytology in the differential diagnosis of accessible paediatric tumours.

In the period 1985-88, 171 fine needle aspirates from paediatric patients with malignant and non-neoplastic masses were processed and evaluated in the Department of Haematology, Kenyatta National Hospital, Nairobi. Sixty-five needle aspirates had the diagnosis corroborated by histological reports. The rest had relevant clinical and laboratory information to support the cytological diagnosis. The histological diagnosis confirmed cytological diagnosis in 100% for neuroblastoma, 96% for Burkitt's lymphoma, 75% for carcinoma, 68% for sarcoma cases, 53% non-Hodgkin's lymphoma and 50% for Hodgkin's lymphoma. There were no false positives. It is therefore concluded that fine needle aspiration is a useful tool. It may obviate diagnostic surgery, help in planning the course of management of patients and it is diagnostic in Burkitt's lymphoma and neuroblastoma. Fine needle aspiration cytology is an easy, cheap and quick investigation compared to surgical biopsy.
