Several salivary diseases, such as Sjogren syndrome (SS), chronic lymphocytic sialadenitis and parotid non-Hodgkin's lymphoma, may occur in the setting of HCV infection. Our aim was to evaluate the prevalence of parotid abnormalities in a cohort of 310 patients with chronic hepatitis C (CHC) attending the Unit of Infectious Diseases of the Garibaldi Nesima Hospital of Catania. Our control group consisted of 188 patients with chronic HBV infection. We found that the prevalence of parotideal diseases was significantly higher among HCV-infected patients in comparison with HBV-infected (17% vs. 1%). Indeed, 53 CHC subjects had parotideal abnormalities: 24 patients (45.3%) had lymphoepithelial cysts of the salivary gland, six patients (11.3%) had a benign tumour, six patients (11.3%) had granulomatous lesions, 12 patients (22.7%) had Sjogren's syndrome and four patients (7.5%) were diagnosed as having chronic lymphocytic sialadenitis. Finally, one patient (1.9%) had parotid non-Hodgkin's lymphoma. In conclusion, parotideal abnormalities are common among HCV-infected individuals and targeted diagnostic protocols may help identify parotid involvement in this population of subjects.

Abstract
Several salivary diseases, such as Sjogren syndrome (SS), chronic lymphocytic sialadenitis and parotid non-Hodgkin's lymphoma, may occur in the setting of HCV infection. Our aim was to evaluate the prevalence of parotid abnormalities in a cohort of 310 patients with chronic hepatitis C (CHC) attending the Unit of Infectious Diseases of the Garibaldi Nesima Hospital of Catania. Our control group consisted of 188 patients with chronic HBV infection. We found that the prevalence of parotideal diseases was significantly higher among HCV-infected patients in comparison with HBV-infected (17% vs. 1%). Indeed, 53 CHC subjects had parotideal abnormalities: 24 patients (45.3%) had lymphoepithelial cysts of the salivary gland, six patients (11.3%) had a benign tumour, six patients (11.3%) had granulomatous lesions, 12 patients (22.7%) had Sjogren's syndrome and four patients (7.5%) were diagnosed as having chronic lymphocytic sialadenitis. Finally, one patient (1.9%) had parotid non-Hodgkin's lymphoma. In conclusion, parotideal abnormalities are common among HCV-infected individuals and targeted diagnostic protocols may help identify parotid involvement in this population of subjects.Pubblicazioni consigliate
