Pancoast tumor mimicking lung tuberculosis, a case report.

It is well-recognized that tuberculosis (TB) can mimic several clinical diseases, particularly cancer. On several occasions, lung TB can be misdiagnosed as cancer, particularly in developed countries with a rare case of TB and high incidence of lung cancer, and vice versa- in which Indonesia, with a high incidence of TB, lung cancer may be mistakenly identified as TB, delaying the initiation of definitive therapy and causing unnecessary diagnostic and treatment procedures. We reported a 59-year-old male who complained of right upper chest pain, accompanied by chronic cough and weight loss, with a history of 6-month treatment with a TB regimen without resolution of his symptoms. Core biopsy CT guiding pathology anatomy revealed atypical adenocarcinoma. All patients seeking medical attention must be treated carefully, avoiding diagnostic procedures that can result in a delay in definitive therapy.
