Resumen

Extrapulmonary tuberculosis accounts for 15-20% of all cases, osteoarticular accounts for 11.3-34.5%. We report here the case of a 28-year-old male immunocompetent host who started with respiratory symptoms and subsequently developed a painful tumor on the second finger of the right hand. He started treatment in a peripheral health care center after identifying Mycobacterium tuberculosis in a sputum sample. Due to the persistence of symptoms, he was transferred to our institution. A biopsy of the tumor was positive for Gene Xpert MTB/RIF, and pathological studies revealed bone involvement of the second finger of the right hand. Incidentally, a vertebral lesion at D9 was found. This report helps consider bone tuberculosis in the differential diagnosis of bone involvement in immunocompetent hosts from endemic areas. © Los autores © Revista Médica Herediana.
