title: Lymphoepithelial cyst in the lung: a case report.
abstract: An unusual endobronchial presentation of lymphoepithelial cysts (LECs) is described in a HIV-seropositive patient. The bilateral infrahilar cysts had followed an apparently benign course for 2 years. Bronchoscopy revealed an endobronchial mass occluding the anterior basilar segment of the left lower lobe. Biopsy resulted in emptying of the cyst and showed the typical pseudostratified columnar epithelium with intraepithelial lymphocytes of an LEC. This diagnosis should be considered in patients with HIV infection and pulmonary cysts on CT.
