Benign lymphoepithelial lesion of the minor salivary gland – A rare presentation as a palatal swelling

摘要

Benign lymphoepithelial lesion (BLEL) is characterized by extensive lymphocytic infiltration of the major salivary glands and may be associated with Sjogren's syndrome or HIV infection. The involvement of the palatal minor salivary glands is extremely rare. We report an isolated case of BLEL affecting the palatal minor salivary glands, presenting as a palatal swelling in a 37-year-old female patient. Serological tests ruled out potential comorbid conditions. Cone-beam computed tomography showed a palatal soft-tissue mass with thinning of the adjacent cortical plates. A histopathological examination revealed salivary gland tissue with significant acinar destruction, dense lymphocytic infiltration and focal myoepithelial islands. Therefore, BLEL may be considered as a rare differential diagnostic possibility of a palatal soft-tissue mass lesion.
