[Management of cervical tuberculous lymphadenitis: evaluation of 6 cases]

Unlike other advanced nations, secondary spread of tuberculosis still occurs in Japan. Cervical tuberculous lymphadenitis is still an important disease of the neck, and between 2001 to 2005, we treated 6 patients with cervical tuberculous lymphadenitis. All 6 patients were females, and their ages ranged from 28 to 77 years old (average: 62 years). One patient had received antitubercular chemotherapy for pulmonary tuberculosis 40 years earlier. Two patients had a family history of pulmonary tuberculosis. One patient was an immigrant from Thailand. Three patients underwent open biopsy of the cervical lymph node, and were diagnosed with tuberculosis histologically. The remaining three patients had an abscess, and fine-needle aspiration (FNA) biopsy was performed. The diagnosis of tuberculosis was made by detection of acid-fast bacilli, MTD (Mycobacterium tuberculosis direct test), PCR (polymerase chain reaction), and culture. All six patients were treated with antitubercular chemotherapy for 6-9 months and recovered. MTD and PCR of the FNA sample seemed to enable early treatment. Attention needs to be paid to countries around Japan where tuberculosis is spreading. We suggest that treatment should be performed while at the same time making an effort to grasp the trend of spread in other countries as well as Japan.
