A 74-year-old white male who was a retired farmer, a nonsmoker and a former drinker presented with a one-year history of chest pain in the suprasternal notch, accompanied by edema and local erythema. His condition had worsened two weeks prior, aggravated by drainage of purulent material from a fistulous lesion. In addition, he reported evening fever, night sweats and weight loss (25 kg) in the last 12 months. The patient was under outpatient follow-up treatment in various sectors of the Santa Maria University Hospital, due to multiple comorbidities: systemic arterial hypertension; heart failure; mitral valve disease; pulmonary arterial hypertension; hypothyroidism; chronic renal failure; nonspecific colitis; and benign prostatic hyperplasia. He was being treated with furosemide, simvastatin, omeprazole, levothy-
IntroductionThe extrapulmonary form of TB involving the sternum is quite rare. The most significant risk factor for the disease is open heart surgery.(1) Other risk factors include intravenous drug abuse, blunt thoracic trauma, closed cardiopulmonary resuscitation, subclavian vein catheterization, diabetes mellitus, HIV infection, alcoholism and BCG vaccination.(1) Sternal TB usually affects young adults living in areas where TB is endemic. Since the advent of modern antituberculous therapy, the number of cases of sternal TB has dramatically decreased, there having been fewer than 20 cases reported in the literature since that time.(2) We report the case of a male patient without active pulmonary disease who was under follow-up treatment at a clinical medicine outpatient clinic when he developed sternal TB.

AbstractWe report the case of a 74-year-old male patient with a one-year history of chest pain in the suprasternal notch associated with erythema, edema and drainage of purulent material from a fistulous lesion. The patient was HIV-negative with no history of TB. A CT scan of the chest showed an osteolytic lesion in the sternum, and a biopsy revealed caseous granuloma, which, in the microbiological evaluation, was negative for fungi and acid-fast bacilli.The diagnosis of sternal osteomyelitis caused by Mycobacterium tuberculosis was confirmed using PCR.
