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]

Parotid gland involvement in advanced AIDS

ORAL DISEASES, Issue 2 2003
PA Vargas
OBJECTIVE: ,This study describes the involvement and the histological alterations found in the parotid glands of 100 patients who died with AIDS. MATERIALS AND METHODS: ,Sex, age, CD4 cell count and clinical history were obtained from the files of 100 patients who died with AIDS. Histological analysis of the parotid glands was performed using H&E, Gomori,Grocott, Ziehl,Neelsen and Mucicarmine. Histological findings were grouped in reactive, infectious, cystic, neoplastic and concomitant lesions. RESULTS: ,None of the patients presented complaints or symptoms related to salivary gland alterations prior to death. The mean age of the patients and CD4 cell count were 36.4 years and 76.07 cells ,l ,1 , respectively. Histological alterations of the parotid glands were found in 51% of the patients. The most common alteration was non-specific chronic sialadenitis (29 cases), followed by infectious conditions (22 cases). Mycobacteriosis was the most common infectious disease (10 cases), followed by cytomegalovirus (nine cases), cryptococcosis (three cases) and histoplasmosis (two cases). Lymphoepithelial cysts occurred in six cases, Warthin's tumor and non-Hodgkin Lymphoma in one case each. CONCLUSIONS: ,These results indicate that infection and other lesions in the parotid glands are more frequent than hitherto described in the specialized literature in AIDS patients. Clinicians should consider parotid gland involvement, when evaluating disease extension in advanced AIDS patients. [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.

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
Glen M. Monama MBChB, MMed (ORL)
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]
