Giant chondrolipoma of the tongue in a 14-year-old child with mandibular hypertrophy. Isolated lesion or regional overgrowth syndrome

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.
