RESUMEN
Chondrolipoma is a rare condition; especially in the oral cavity. The authors described a giant chondrolipoma of the tongue, associated with mandibular and lower lip overgrowth, in a 14-year-old boy. After tumour excision, histopathological examination showed mature cartilage within lobules of mature adipocytes. This is the first case of giant chondrolipoma associated with facial overgrowth. The aetiology and the association with a localized Proteus syndrome are discussed.

We presented three cases in which two bipedicled fasciocutaneous flaps were used for coverage defects of the knee. These bipedicled flaps can be harvested to cover long and narrow sized defects on the anteromedial aspect of the knee region. This procedure is easy, quick and versatile without compromising the principal vessels and muscles of the leg.

Carpal skeleton shows drastic developmental changes during embryogenesis. At this stage, the cartilaginous matrices appear and later form models of the limb bones. The purpose of this study was to investigate the morphometry of carpal bones in humans during embryological development. We obtained digitalized histological serial sections of 18 human embryos and early fetuses from the Institute of Anatomy in Paris. Surfdriver and MSC.Patran software were used for three-dimensional reconstruction and morphometry. There was a strong correlation between the volume of the carpal cartilaginous structure and the size of the embryos (P<0.001) and an exponential correlation between the carpal volume and the percentage of volume presented by the proximal carpal row (P=0.005). According to inertia parameters, the geometry of carpal cartilaginous structure, initially plane, becomes curved during embryogenesis. Carpal bones growth follows non-homothetic transformation. The innovations in embryo reconstruction serve as new tool for scientific investigation. A hypothesis of carpal development is proposed.
