Tuberculosis is a public health problem that still maintains importance in all developed and developing countries. In childhood tuberculosis, unlike adults, presenting less classical findings and the low rate of detection of the agent by microbiological methods create difficulties in diagnosis. The aim of this study was to evaluate the clinical, laboratory and radiological findings of patients followed up with the diagnosis of tuberculosis disease in our clinic. Thirty-four patients who were followed up with the diagnosis of tuberculosis disease in our clinic on January 2014-December 2019 were included in the study and the files of the patients were reviewed retrospectively. Fifty percent (n:17) of the patients were male, with a median age of diagnosis was 153.5 mos (17-218 months). Thirteen patients were diagnosed with pulmonary, 8 patients with disseminated, 6 patients with gastrointestinal, 6 patients with lymph node and 1 patient with joint tuberculosis. While there were 8 (23.5%) patients with a history of tuberculosis contact, the most common complaints were cough, abdominal pain, weight loss and fever. Eight (23.5%) patients had no pathological findings at the time of admission. While tuberculine skin test was positive in 17 (50%) patients, tubercle bacillus was demonstrated by microbiological methods in seven patients. One patient diagnosed tuberculosis disease by, with a positive response to treatment and exclusion of other diseases. While the treatment was interrupted for a short time due to side effects in four (11.8%) patients, no serious side effects were observed in any of the patients. The diagnosis is made by combining clinical, laboratory and radiological findings, and sometimes patients can be diagnosed with the positive response of the patient to the treatment.
