摘要

弓蟲症是遍佈世界各地的人畜共通病，有很高的盛行率。世界約有75%的人曾受過感染，台大研究報告台北之弓蟲症IgG抗體盛行率約為7%左右。對免疫系統健全的人，頸部淋巴結炎是急性後天性弓蟲症最常見的臨床表徵，所以對於不明原因的頭部腫塊，若發生在喜好生食的病患上，應考慮弓蟲症淋巴結炎。本例患者為一名37歲女性，因右頸淋巴結腫大至本院檢查，投予廣效抗生素後仍持續變大。經病理切片和血清抗體佐證下證實為弓蟲症感染。投予磺胺類抗生素一個月，追蹤至今半年並無復發跡象。

Toxoplasmosis is a worldwide zoonotic protozoa infestation with high prevalence. Up to 15% of unexplained cervical lymphadenitis had been reported. A 37 -year-old female presented to our clinic with an unexplained right posterior neck mass. Excisional biopsy showed characteristic histologic feature of toxoplasmic lymphadenitis which was later confirmed by serological test (enzyme-immuno-assay IgG antibody test). Prophylactic oral antibiotic was given due to the propagation of lymphadenitis to the inguinal area. The patient was well after 6 months of follow-up. We reviewed the literature and discussed the case. Although toxoplasmic lymphadenitis is self-limited in immunocompetent people, toxoplasmosis in immunocompromised patients and in pregnant women may result in mortality. Toxoplasmic lymphadenitis should be included in the differential diagnosis of cervical lymphadenopathy.
