. Some of the clinical and histological features of 12 retention and 224 extravasation mucoceles of minor oral salivary glands are compared. Retention mucoceles occurred in a much older age group than extravasation mucoceles, and were very uncommon in the lower lip which was by far the most frequent site for extravasation mucoceles. All the retention mucoceles were lined by eosinophilic, oncocyte‐like epithelium as either a double or a single layer of columnar, cuboidal or compressed flat cells. There is no evidence to support the generally accepted suggestion that retention mucoceles are due to duct blockage, and it is postulated that either they may arise as spontaneous cystic change in an oncocyte‐lined duct, or they represent a cystic type of papillary cystadenoma.
