Residual radicular cysts also called residual cysts, are inflammatory odontogenic cysts of the tooth‐bearing areas of the jaws. Some authors believe that they are not distinct entities, but represent previously undetected or persistent radicular cysts. Though they are slow‐growing and are usually found incidentally, they have the potential to reach massive sizes, displace adjacent structures and transform into benign and malignant tumours. In comparison to other odontogenic cysts, there is a paucity of literature regarding residual cysts. This article comprehensively reviews the literature available on the etiopathogenesis, presentation, microscopic and biochemical features, management and prognosis of residual cysts along with a report of a large residual cyst in the maxilla, displacing the maxillary sinus. The cyst presented 10 years after extraction of the offending teeth and was filled with brownish‐red semisolid content, which is uncommon. The lesion was enucleated and no postoperative complications were observed.
