We report the fourth case of subcutaneous cysticercosis infected in Japan since 1975. The patient noticed a subcutaneous nodule on his left shoulder without symptoms for three years. No remarkable changes were found in laboratory findings and physical examination after surgical excision of the subcutaneous nodule. The adult worm of Taenia solium could not be found in the intestine. Histological findings revealed a cystic structure with a fibrous capsule and a protoscolex with suckers, hooks, and calcareous corpuscula. It was identified as a Cysticercus cellulosae hominis based on morphological characteristics. The patient has been living in the Kanto area of Japan and has never been outside Japan since he was born.
我们报告了自1975年以来日本第四例皮下囊尾蚴病感染病例。患者发现左肩有一个皮下结节，三年来没有症状。皮下结节手术切除后，实验室检查结果和体格检查均未发现明显变化。在肠道中未发现猪带绦虫成虫。组织学检查发现一个有纤维包膜的囊性结构和一个带有吸盘、钩子和石灰小体的原头节。根据形态学特征，它被鉴定为人囊尾蚴。患者一直生活在日本关东地区，自出生以来从未出过日本。
