An 81 year-old male patient presented with rapid enlargement of left lateral neck mass, diagnosed two months earlier as cervical nontuberculous mycobacterial lymphadenitis. Abscess formation and impending rupture related to aggravation of nontuberculous mycobacterial lymphadenitis was highly suspected. Unexpectedly, blood flow was detected by Doppler ultrasonography, which indicated possible vascular mass. Computed tomography demonstrated a $6.0cm{\times}4.0cm$ sized enhancing mass consistent with pseudoaneurysm of internal carotid artery. The patient underwent pseudoaneurysmectomy. Surgical drainage without adequate evaluation might have led to potentially life-threatening condition. We describe this rare case with importance of imaging screening in a neck mass.

Background: Cervical tuberculous lymphadenitis is the most common form of peripheral tuberculous lymphadenitis. The American Thoracic Society recommends 6 months of isoniazid, ritampin, ethambutol and pyrazinamide for treatment of peripheral tuberculous lymphadenifls, but even with this recommended treatment, frequent relapse occurs in actual clinical situations. Material and Method: The medical records of 38 patients diagnosed and treated for cervical tuberculous lymphadenitis between February 1997 and February 2007 were retrospectively reviewed. Result: The study included 14 males (36.8%) and 24 females (63.2%), with a mean age of $36.9{\pm}16.3$ years. The most frequent symptom was palpable neck mass in 24 patients (63.2%); 10 patients (26.3%) complained of fever or chills. Only nine patients (23.7%) had radiologic abnormalities. All patients received anti-tuberculous medications for at least 7 months, with isoniazid, rifampin, ethambutol and pyrazinamide for the first 2 months, and then isoniazid, rifampin and ethambutol given for more than 5 months. Relapse occurred in 7 patients (21.2%). Conclusion: Since many patients with cervical tuberculous lymphadenitis have no symptoms and show no radiologic abnormalities, diagnosis and treatment tend to be delayed. Considering the high relapse rate, the anti-tuberculous medication period should be longer than 6 months and this is recommended by the American Thoracic Society.

A mass appearing in the anterior or lateral side of neck often can be a diagnostic challenge. Differential diagnosis of the neck mass covers a broad spectrum of diseases and the proper evaluation and management of a neck mass requires an impressive amount of anatomic and pathologic information. Because improper diagnosis and management may convert a potentially curable malignant metastasis into incurable disease, a differential diagnosis must be considered in all patients who present with a neck mass. Authors reviewed 2,148 cases of neck mass who were diagnosed by surgical resection, biopsy or aspiration during the period between October 1982 to December 1993, excluding those with thyroid and parathyroid disease. The evaluated characteristics were age, sex, site of lesion, and pathologic diagnosis. The results were as follows: Of 2,148 cases of neck mass, the overall ratio of benign to malignant tumor was 3 : 1. In 1,603 cases of benign mass lesion, the most common disease was lymphadenitis(non-specific and tuberculosis) showing 53% incidence, the second was salivary gland tumor(13%), and the third was congenital lesion(12%). The minor problems such as lipoma and sebaceous cyst were 21 %. In the age distribution of benign lesion, tuberculous lymphadenitis showed peak incidence in second decade, non-specific lymphadenitis was main disease of childhood, salivary gland tumor was peak in fourth decade, and most of congenital lesions were diagnosed at the age below 15. In 545 malignant tumors, the most common lesion was metastatic cancer to cervical lymph nodes yielding 71 % incidence(head and neck primary 52%, infraclavicular primary 42%, unknown primary 5%), the second common disease was lymphoma(19%), and the third was salivary gland cancer(9%). In the age incidence of malignant tumor, 60% of them developed in the fifth and sixth decade, head and neck primary was more common in the fifth decade than sixth, however lymphoma showed higher incidence in sixth decade. In the analysis of mass location according to lymph node level grouping(I - V), lymphadenitis developed mostly in level V nodes, the next common occurring site was level IV in tuberculous lymphadenitis and level II in non-specific lymphadenitis. The majority of metastatic cancers were found in level IV and III, and common occurring site of lymphoma was in level II and IV. Pathologic diagnosis of neck masses were made by fine needle aspiration cytology 80 cases, incisional biopsy 533 cases, excisional surgery 1,399 cases, and neck dissection 116 cases. For the proper management of neck mass, a proper diagnostic modality should be selected from imaging techniques, cytology, biopsy or neck dissection, with the consideration of patient's age, history and clinical findings. The scapel biopsy could be used freely in the inflammatory disease or inoperable metastatic cancer, but it should be reserved in the curable metastatic cancer or clinically possible malignancy.

A group of patients with Kawasaki disease (KD) initially present with cervical lymphadenitis or deep neck infection. These unusual KD presentations lead to unnecessary antibiotic therapy or surgical intervention, thereby delaying intravenous immunoglobulin treatment and increasing the risk of coronary artery damage. We present four KD patients whose initial presentations mimicked a retropharyngeal abscess. Nonsuppurative cervical lymphadenitis or suspected neck abscess unresponsive to intravenous antibiotics could signal the possibility of KD.

Background: Tuberculous cervical lymphadenitis is one of the common causes of cervical mass in adult (especially in woman) in korea. Sometimes it appears to be difficult in defining the role of surgery and duration of antituberculous chemotherapy. Method: To clarify the proper duration and/or combination of regimens, we analyzed the clinical data of 31 patient with cervical lymphadenitis diagnosed at Chungnam National University Hospital from March 1996 to December 1996 and all patients were prospectively randomized into two groups(2HREZ/4HRE and 6HREZ) by treatment method. Result: Prevalent age, male to female ratio, association with pulmonary tuberculosis and history of previous antituberculous medication were not statistically different between two groups. The average size of the largest lymph node before teatment was $2.43{\pm}0.98cm$ and $3.15{\pm}1.74cm$, respectively and was 0.63cm and 0.6cm after treatment, respectively. In both groups, 2 patients have engrowing node or not changed node during tratment and no recurrence was found during follow up period upto 12 months. In both groups, no significant side reaction resulting in discotinuation or changing the regimens was noticed. Conclusion: Short course antituberculosis therapy(2HREZ/4HRE) could be recommanded as effective standard therapy for superficial lymph node tuberculosis. Longterm follow up at least 36 months to observe recurrence might be needed to confirm this conclusion.

Kikuchi's disease (KD) is an idiopathic and self-limiting necrotizing lymphadenitis that predominantly occurs in young females. It is common in Asia, and the cervical lymph nodes are commonly involved. Generally, KD has symptoms and signs of lymph node tenderness, fever, and leukocytopenia, but there are no reports on treatment for the associated myofacial pain. We herein report a young female patient who visited a pain clinic and received a trigger point injection 2 weeks before the diagnosis of KD. When young female patients with myofascial pain visit a pain clinic, doctors should be concerned about the possibility of KD, which is rare but can cause severe complications.

Kikuchi disease is a type of benign, self-limiting necrotizing lymphadenitis that occurs most commonly in young women and usually manifests as palpable cervical lymph nodes and fever. Patients with an unusual location of lymph node involvement can be misdiagnosed with malignant disease. Here, we report a case of Kikuchi disease in a 15-year-old girl presenting with persistent fever for 2 weeks. Imaging studies, including ultrasonography, CT, and ¹⁸F-fluorodeoxyglucose PET/CT, revealed splenomegaly and enlarged lymph nodes in the neck, axilla, abdomen, retroperitoneum, and inguinal region. Laparoscopic excision of the celiac lymph nodes confirmed histiocytic necrotizing lymphadenitis, also known as Kikuchi disease. Conservative treatment with corticosteroids improved the patient's condition.

Background : The aim of this study was to analyze the clinical manifestations and efficacy of treatment regimens in order to determine the adequate combination of anti-tuberculotic agents and duration of treatment for tuberculous lymphadenitis. Methods : We made a review of 373 patients with tuberculous lymphadenitis, who were admitted to four medical college hospitals in Taegu Korea from 1989 to 1998, and their diagnoses were confirmed histologically and bacteriologically. Results : The incidence of tuberculous lymphadenitis was 71.3% in women and 57.7% were between the ages of 20 and 39 years. The most common symptom was painless swelling. The most commonly involved lymph nodes were unilateral superficial cervical lymph node groups. Tuberculous lymphadenitis was accompanied with active pulmonary tuberculosis, commonly. The sensitivity of fine needle aspiration(FNA) in tuberculous lymphadenitis was 79.6%, and 92.2% of the patients had a strong positive reaction to the tuberculin skin test. The most commonly prescribed anti-tuberculotic regimen was the combination of INH, RMP, EMB, and PZA(62.6 %). Eighty percent of patient were treated for 9-12 months. There was no significantly difference in the recurrence rate of tuberculous lymphadenitis between the combinations of anti-tuberculotic agent, including INH and RMP, and between the durations of treatment, for a period of 6 months of more. Conclusion : The combination of FNA cytologic examination and tuberculin skin test may be helpful in the diagnosis of tuberculous lymphadenitis. We propose that the combination of anti-tuberculotic agents, INH, RMP, EMB, and PZA, be prescribed to patients for 6 to 9 months.

Tuberculous cervical lymphadenitis is still an important cause of neck mass in Korea. Tuberculosis is an important differential diagnosis in patients of cervical lymphadenopathy. Rapid and sensitive test for the diagnosis of tuberculosis is essential for the approapiate treatment. Up to now, conventional diagnostic methods for M. tuberculosis were acid-fast bacilli(AFB) stain and culture of M. tuberculosis. The direct microscopic examination of AFB by Ziehl-Neelsen stain is rapid, but often negative. The culture for M. tuberculosis is time-consuming, taking 4 to 8 weeks. Recently various methods to detect Mycobacterial DNA, including PCR and restriction fragment length polymorphism(RFLP) analysis have been reported. Here we represent a simple method for the confirmation of M. tuberculosis and exclusion of the other Mycobacterial species by RFLP analysis and silver staining of polyacrylamide gel electrophoresis after nested PCR for a repetitive DNA sequence(IS986) specific for M. tuberculosis from fresh or paraffin-embedded biopsy specimens. This result leads us to conclude that this method is simple, rapid and possibly applicable to confirm M. tuberculosis and rule out the other Mycobacteria species from the clinical specimens in the clinical laboratories.

Purpose : Kawasaki disease (KD) rarely occurs in school-aged children. We clarified the characteristics of KD in this age group to provide tips for a high index of suspicion. Methods : Features of 38 patients with KD who were 7 years of age or older were retrospectively reviewed. Results : The incidence of the KD patients ${\geq}7years$ was 4.9 percent. The ratio of male to female was 2.5:1. Of the 38 patients, nine patients (24.0 percent) were diagnosed with typical KD and 29 patients (76.0 percent) with incomplete KD. In incomplete KD patients, cervical lymphadenopathy (69.0 percent) occurred most frequently, followed by conjunctival injection (62.0 percent) and polymorphous rash (45.0 percent). These patients occasionally presented with other additional symptoms including abdominal pain, headache, vomiting and arthralgia. Incomplete KD was initially diagnosed as cervical lymphadenitis (34.0 percent), viral infection (14.0 percent), scarlet fever (7.0 percent), meningitis (7.0 percent), and Kikuchi disease (7.0 percent). Coronary complications were noted in 15 patients (39.0 percent). Of the 37 patients treated with intravenous immunoglobulin, five (14.0 percent) were resistant to the therapy and all had coronary abnormalities. Conclusion : Most patients with KD ${\geq}7years$ of age have incomplete presentations. They tend to have a higher incidence of initial presentations of unilateral neck mass and coronary artery involvement. In school-aged children, fever and cervical lymphadenitis or suspected neck infection unresponsive to intravenous antibiotics should signal the possibility of KD. A high index of suspicion and prompt treatment is essential in this age group of patients.
