Clinicopathological Characteristics of Lymphadenitis Caused by Talaromyces marneffei Diagnosed by Core Needle Biopsy
Objective To analyze the clinicopathological characteristics of lymphadenitis caused by Talaromyces marneffei (TM).Method s The clinical data,pathological features,pathogen examination,and treatment of 15 cases of TM-caused lymphadenitis were analyzed retrospectively.Results The 15 cases included 14 males and 1 females,who were aged 26-67 years,with an average age of (49.1±11.87) years.The 15 cases,including 13 cases of acquired immunodeficiency syndrome and 2 cases of diabetes mellitus,were accompanied by superficial lymph node enlargement in the neck and supraclavicular,axillary,and inguinal regions.The structure of cord-like lymph node tissue punctured by thick needle was completely or partially replaced by inflammatory lesions. Under microscope,8 cases showed mainly diffuse infiltration of phagocytes with pathogens;5 cases presented mainly extensive coagulation necrosis with a small amount of pathogens and nuclear debris;2 cases were characterized by small nodular hyperplasia of fibroblasts,formation of granulomatous structure,and scattered distribution of a few multinucleated giant cells.The pathogens were relatively consistent in size and shape,which were round,oval or sausage-shaped and clustered like mulberry.Diastase periodic acid-Schiff staining and hexamine silver staining highlighted the bacterial structure with transverse septum.TM growth was detected in the blood,alveolar lavage fluid,sputum or lymph node extract fungal culture of the 15 patients.Owing to the adequate antifungal treatment in time,these 15 patients were discharged after their conditions were improved.Conclusion Lymphadenitis is one of the major manifestations of the systemic invasion of TM at the late stage,which is tended to be misdiagnosed.Through core needle biopsy of lymph node,it can be diagnosed as soon as possible to avoid delayed treatment and improve the cure rate.
