[Metatarsal metastasis. A case treated by exeresis an reconstruction]

The authors are reporting a case of an isolated metatarsal metastatic tumour revealing a light-celled kidney "adenocarcinoma". Occurring rarely, metastatic lesions of the foot, of which less than a hundred observations have been reported so far, are mainly side-effects of the uro-genital sphere and digestive cancers. In the present case, the metastatic singleness and the good control of the initial tumour justified the total removal of the first metatarsal which posed the problem of reconstruction. The use of a fibula auto-graft allowing the realisation of a double cuneo-metatarsal and metatarsal-phalangeal arthrodesis joint made it possible to resume weight bearing and walking on the second month and to preserve the functional result on the 21 st.
