COVID-19-associated parotitis and sublingual gland sialadenitis

The COVID-19 mainly affects the respiratory system; however, a variety of atypical manifestations of this disease have been also reported. Herein, we report a case of a man in his late 50s with severe COVID-19 presenting with parotitis and sublingual gland sialadenitis. Six days after admission, swelling in the bilateral preauricular and lower jaw areas developed. CT demonstrated parotid and sublingual gland enlargement with surrounding fat stranding, indicating sialadenitis. This case suggests that, in the present COVID-19 pandemic, COVID-19 should be included in the differential diagnosis of sialadenitis and prompt isolation should be considered to reduce the spread of infection.
