Legg-Calve-Perthes' disease associated with chronic myeloid leukaemia in a child: case report.

Chronic myeloid leukaemia was discovered in a female child aged 12 years, whose presenting signs and symptoms were those of Legg-Calve-Perthes' disease in the left hip. The chronic myeloid leukaemia responded dramatically to myeleran therapy, whilst the Legg-Calve-Perthes' disease was treated by bed rest in hospital followed by weight-relieving paten-ended calliper. A rare case of CML in a female child who has 'Legg-Calve-Perthes' disease of the left hip in association is described.
