Objective: to investigate the situation, clinical and laboratory features of CT at the National hospital of Dermatology and Venereology (NHDV). Method: the prospective cross-sectional study based on data collected from 27 patient records diagnosed as CT at the NHDV from 1/2007 to 1/2012. Results: During 5 years, there were 13 patients with CT (0.16 percent in-patients), in which 84.61 percent of patients over 40 years old. Males and females were almost equal. 76.9 percent came from rural area. The most common clinical type was lupus vulgaris - LV (76.9 percent). 87.5 percent. The most frequent lesions were exposed area such as arm, leg, head, face and neck (87.5 percent). Lesions were papules, plaque of papules (69.2 percent) with centrifused evolution, healing centre (53.8 percent), welllimited border (100 percent), red, brownish red (100 percent) and others as verrucose, ulcer, tubercle, gomme and atrophic lesions. There were 66.7 percent patients having tuberculous follicles in histopathology, but in which only 8.3 percent having AFB. Conclusion: CT is a rare skin disease. The most clinical type is LV. The lesions are like some other skin disease, so it is easy to have a mistake in diagnosis. Tubercle is a specific lesion to definitive diagnose LV but not appear in all patients with LV. Histopathology and AFB confirm the diagnosis.
