Upington disease is an extremely rare disease having only one published source claiming its existence on one family in three generations from South Africa. The disease is characterised by Perthes-like pelvic anomalies (premature closure of the capital femoral epiphyses and widened femoral necks with flattened femoral heads), enchondromata and ecchondromata. A autosomal dominant form of inheritance has been suggested. The name Upington refers to the district of the Cape Province, South Africa where the family originates from.
