title: Benign lymphoepithelial lesions of the parotid.
abstract: Persistent generalized lymphadenopathy has been well described in patients with seropositivity to the human immunodeficiency virus (HIV). Moreover, isolated enlargement of the parotid gland and parotid lymphadenopathy have been noted much more frequently over the past few years. Histologically, these lesions demonstrate follicular hyperplasia, cystic dilatation of the ducts lined by pseudo-stratified squamous epithelium, and lymphocytic infiltrates. They are generally considered to be benign lymphoepithelial lesions of the parotid or hyperplastic periparotid lymph nodes. The relationship of this entity to the AIDS-related complex (ARC) and the subsequent development of AIDS is not clear. Over the past 7 years, we have seen 50 patients with parotid enlargement in whom the diagnosis of benign lymphoepithelial lesion was made. Fine-needle aspiration was performed in 32 patients. Although not conclusively diagnostic, needle aspirates ruled out primary salivary glandular pathology. Most patients gave a history of intravenous drug abuse. HIV tests have been performed on a routine basis only in the last 2 years, and these were positive in the majority of the patients. Thirty-five patients underwent surgical excision. In the initial 20 patients, we routinely performed parotid exploration, identification of the facial nerve, and superficial parotidectomy. In the last 15 patients, we changed our surgical approach to parotid exploration and excision of the mass in the tail of the parotid. The exposure of the posterior belly of the digastric muscle, with identification and removal of the deep jugular node, has become routine. In each case, we found an enlarged lymph node in the deep jugular region, which was not clinically palpable preoperatively. The rate of surgical complications was minimal, and, after resection of the mass, patients improved symptomatically. If the patient shows obvious signs of AIDS, a nonsurgical approach with repeated aspirations should be considered, and treatment with zidovudine offered.
