Abstract
|
|
|
Actinomycosis is a rare anaerobic, gram-positive bacterial infection caused by Actinomyces.
As an infection site for the disease, the cervicofacial area is common but the nasal cavity andthe nasopharynx are rare. Actinomycosis causes chronic purulent granulomatous infection andis characterized by extensive infiltration, necrosis, and bone destruction on CT. Extranodalnatural killer/T cell (NK/T cell) lymphoma, nasal type is more common in East Asia thanelsewhere, comprising up to 7%-10% of all non-Hodgkin’s lymphoma. Early nasal symptomsare nonspecific and similar to chronic rhinosinusitis, such as nasal obstruction and nasalbleeding. With disease progression, inflammation and necrosis of the mucosa increase. Weexperienced a case of extranodal NK/T cell lymphoma in a 60-year-old female, who was diagnosedwith opportunistic infection of actinomycosis. We report this case with a review ofliterature.
