BLECs are believed to develop due to lymphoid hyperplasia of embryologically sequestered lymphatic tissue within the parotid gland. (3) There are two theories as to the pathogenesis: (a) the obstructive theory, which states that lymphoid hyperplasia in the parotid leads to ductal obstruction and salivary dilatation, like a true cyst; (b) HIV-related reactive lymphoproliferation occurs in the intra-parotid lymph nodes resulting in trapping of parotid glandular epithelium causing cystic enlargement.
