In nonneoplastic lesions there were 10 cases of sialadenitis and two cases each of mucocele and lymphoepithelial cyst
. Results of benign and malignant lesions are shown in tables given below.
Various causes of parotid enlargement in seropositive (HIV) patients are diffuse infiltrative lymphocytosis syndrome, parotitis, intraparotid lymphadenopathy; benign lymphoepithelial cyst
(BLEC), adenoid cystic carcinoma, Kaposi sarcoma, and lymphoma.

Moreover, differential diagnosis should be made of smears with noncancerous and cancerous lesions containing lymphocytic cells, namely chronic inflammation of the salivary gland, reactive inflammation of lymph nodes, lymphoepithelial cyst

(1, 2) LEL has been variably designated as Sjogren-like syndrome, benign lymphoepithelial lesion, cystic lymphoepithelial lesion, HIV salivary gland disease and lymphoepithelial cyst
. Increasingly, in our practice, the profile of parotidectomy has changed, with LEL becoming a common indication for parotidectomy, prompting a review of our current experience.
Histopathological report confirmed the presence of lymphoepithelial cyst

The most common lesion is the benign lymphoepithelial cyst
. Malignant lesions may also be associated with--or be hidden by--a cystic mass.
Less common branchial cleft anomalies include a first BCC, or a parotid lymphoepithelial cyst
, arising from a tract extending from the external auditory canal through the parotid to the submandibular triangle (Figure 5).
