Role of Cytomegalovirus, Epstein-Barr Virus, and Human Herpes Virus-8 in Benign Lymphoepithelial Cysts of the Parotid Gland

THE LARYNGOSCOPE, Issue 8 2004
Thomas L. Yen MD
Abstract Objective: To provide background and evaluate the role of herpesviruses in benign lymphoepithelial cysts (BLC) of the parotid gland. Study Design: Case series derived from review of pathology specimens. Methods: Radiolabeled polymerase chain reaction (PCR) analysis was used to detect for the presence of cytomegalovirus (CMV), Epstein-Barr virus (EBV), and human herpes virus 8 (HHV-8) DNA sequences in 14 paraffin embedded specimens and 1 freshly aspirated BLC specimen. Thirteen normal parotid tissue specimens obtained from paraffin embedded blocks were used as a control group. Results: CMV was detected with nearly equal frequency between the two groups (23% of normal vs. 20% in BLC). HHV-8 was found in 13% of the BLC group and in none of the normal group (P = .4841). There was significant difference in EBV detection between the normal (0%) and the BLC (33%) groups (P = .0437). Conclusion: CMV and HHV-8 does not appear to be associated with BLCs. Although EBV is found more frequently in BLC than in normal parotid controls, further studies are needed to elucidate the role of this virus in BLC pathogenesis. [source]

Intralesional bleomycin injections in the treatment of benign lymphoepithelial cysts of the parotid gland in HIV-positive patients: Case reports,

THE LARYNGOSCOPE, Issue 2 2010

Abstract Benign lymphoepithelial cysts (BLCs) of the parotid gland are associated with human immunodeficiency virus. These cysts may grow large and uncomfortable, causing significant cosmetic embarrassment for the patient. Several treatment options have been described with varying successes. We report successful treatment of three adults with bleomycin. All three patients presented with bilateral parotid enlargements. They received a total dose of between 180 U and 270 U of bleomycin over a period of 6 to 10 weeks. They all responded completely without morbidity or recurrence. Bleomycin is effective in the treatment of BLCs of the parotid glands in HIV-positive patients. Laryngoscope, 2010 [source]

Fine-needle aspiration cytology of basal cell adenoma of the parotid gland: Characteristic cytological features and diagnostic pitfalls

DIAGNOSTIC CYTOPATHOLOGY, Issue 2 2007
Akihiko Kawahara C.T., Ph.D. C.M.I.A.C.
Abstract We retrospectively studied the cytological features of aspiration cytology in 12 cases of basal cell adenoma (BCA) and 5 cases mistakenly diagnosed as BCA. On macroscopic findings, the 12 cases of BCA included 7 cases of solid type and 5 cases of cystic type. The characteristic cytological features of solid type BCA were three-dimensional clusters in 71%, sharp-angle small clusters in 86%, basement membrane- like material in 71%, and cell crush in 86%. In contrast, 3 of the 5 cystic type BCA cases showed inadequate cellular components or no basaloid tumor cells, and the cytological diagnosis of BCA could not be determined. In the 5 cases misdiagnosed as BCA, there were 2 cases of pleomorphic adenoma, 2 cases of benign lymphoepithelial cyst, and 1 case of basal cell adenocarcinoma. Accurate differential cytological diagnosis of BCA is relatively easy to determine the solid type BCA, but is more difficult for cystic type BCA. Diagn.
