بررسي فراواني لنفادنيت گرانولوماتوزي سر و گردن و نتايج رنگ آميزي زيل نلسون

The incidence of head and neck granolumatosis lymphadenitis and the results of Zeihl-Nelson reaction.

Background and Aim: Tuberclusis is a chronic disease which can be seen in pulmonary and extrapulmonary forms. This disease can cause granolumatosis reaction and caseose necrosis. The common form of extrapulmonary form is cervical lymphadenitis that mostly occur in posterior neck trigle which can make dermal fisula dignosis is done by needle asprition, smear, culture and biopsy. This study was carried out for determining of incidence of granolumatosis lymphadenitis in head and neck and relation with the results of Zeihl-Nelson staining. Materials and Methods: This discriptive and cross-sectional study was done with reffering to pathological ward in 5th Azar Medical Education hospital during six years. Lymphadenitis slides of head and neck were surveyed more carefully. Results : 156 cases were determind with lymphadenitis in head and neck area. In microscopic examination, positive granolumatosis reaction, caseose necrosis and positive acid fast reaction were seen in 35, 30 and 8 cases respectively. The most patients with neck lymphadenitis were in 11-20 years old group and the lowest rate were over 60 years old. The distribution of granolumotosis lymphadenitis were observed in 11-20, 31-40 and 41-50 age group. Conclusion : Since only 22% of the patients with granolumatosis lymphadenitis had positive acid fast reaction with Zeihl-Nelson staining and because of the high incidence of TB. We cannot rely only on results of staining. Therefore, we must start treatment patients with report of granolumatosis reaction in pathology and positive symptoms and signs.
