  A patient in the early stage of TB disease may be asymptomatic or have nonspecific symptoms, such as anorexia, fatigue, weight loss, low-grade fever, night sweats, chest pain, shortness of breath, fever, and a productive cough with occasional hemoptysis [journals.lww.com]

  As there are no direct tests for asymptomatic infection, it is inferred from the presence of TB immunoreactivity, determined by either a tuberculin skin test (TST) or an interferon gamma release assay (IGRA). [bmj.com]

  These other conditions include tropical phagedenic ulcers, chronic lower leg ulcers due to arterial and venous insufficiency (often in the older and elderly populations), diabetic ulcers, cutaneous leishmaniasis, extensive ulcerative yaws and ulcers caused [who.int]

  […] about 7–14 days after infection through broken skin Over one to two months the nodule may break down to form a shallow ulcer that spreads rapidly and may involve up to 15% of the patient's skin surface Ulceration and necrosis are due to a toxin, mycolactone [dermnetnz.org]

  In those treated with antibiotics alone, 83.0% experienced a reduction in induration size after 2 weeks, then 70.9% experienced an increase in induration size from the lowest point, and 71.7% experienced an increase in ulceration size. [ncbi.nlm.nih.gov]

On workup, it was confirmed that M. chelonae was the causative organism. He was given 8 weeks of antibiotics; however, there was worsening of the hip abscess on interval imaging. [ncbi.nlm.nih.gov]

After 4 days of incubation on the automated instrument, the two aerobic blood cultures bottles were positive and the patient was admitted to the hospital for further workup and therapy. [labmedicineblog.com]

(See Workup). In areas with a high prevalence of tuberculosis (TB), most cases of MAC infection are misdiagnosed and treated as TB. [3] In general, MAC infection is treated with 2 or 3 antimicrobials for at least 12 months. [emedicine.medscape.com]

• Multiple Pulmonary Nodules
