Diagnostic and Treatment Challenges of Adult-Onset Still's Disease in the Background of Pulmonary Tuberculosis.

Adult-onset Still's disease is a multisystem inflammatory disease characterized by fever, rashes, arthritis, and sore throat. The occurrence of this disease and pulmonary tuberculosis is infrequent, and more data are needed in the literature regarding both conditions. We present the case of a 48-year-old woman undergoing treatment for sputum-positive pulmonary tuberculosis who presented with features suggestive of adult-onset Still's disease. A detailed evaluation led to the diagnosis of adult-onset still's disease with pulmonary tuberculosis, and the patient was managed accordingly.
