HIV-associated parotid lymphoepithelial cyst

Monday 19 June 2017

Histologically, lymphoepithelial cysts can be classified into 3 subtypes:
- type I, a cystic dilation of ducts within parotid glands (14.1%);
- type II, partially demarcated cystic lesions with lymphoid stroma (42.2%);
- type III, well-encapsulated cystic lesions with lymphoid stroma containing lymph follicular structures (43.8%).

Lymphoid stroma is induced along with the growth of the cystic dilatation of ducts within sialadenitis.

Cystic lymphoepithelial lesion can be an HIV associated cyst that is frequently bilateral.

Cytology shows epithelial cell groups and lymphocytes.
