Abstract:
A 57-year-old man with untreated diabetes mellitus was admitted to our hospital due to an intrathoracic mass lesion infiltrating the vertebral body and mediastinum. The mass was suspected to be invasive lung cancer; however, percutaneous needle biopsy revealed that the mass was inflammatory granulation tissue caused by an Arcanobacterium haemolyticum infection. To the best of our knowledge, this is the first report of an intrathoracic mass lesion caused by an A. haemolyticum infection. When an intrathoracic mass lesion is suspected, clinicians should consider possible infections that cause granulation tissue, such as A. haemolyticum. This is particularly important in immunocompromized hosts such as patients with diabetes.
摘要:
由于胸腔内肿块病变浸润椎体和纵隔,一名未经治疗的57岁糖尿病患者入院。该肿块被怀疑是浸润性肺癌;然而,经皮穿刺活检显示肿块是由溶血性弧菌感染引起的炎性肉芽组织。据我们所知,这是由溶血性芽孢杆菌感染引起的胸腔内肿块病变的首例报告.当怀疑胸内肿块病变时,临床医生应考虑可能引起肉芽组织的感染,如溶血曲霉。这在免疫增强宿主如糖尿病患者中尤其重要。
