Extensive Multisystemic Disseminated Tuberculosis in an Immunocompetent Patient.

Extrapulmonary tuberculosis is uncommon and has an insidious onset with slow evolution and a paucibacillary nature. Here, we present a case of disseminated tuberculosis in an adult immunocompetent man presenting with morphologically different types of cutaneous lesions (i.e., multiple subcutaneous abcesses and multiple noduloulcerative lesions with discharging sinuses with seropurulent fluid). Extensive screening in the form of routine blood investigations, serologies, skin biopsy, Montoux test, sputum examination, chest and skull roentgenogram, noncontrast computed tomography chest and abdomen, contrast-enhanced computed tomography of the skull, and magnetic resonance imaging of lumbosacral spine with screening of the whole spine revealed extensive involvement of the skin, subcutaneous tissue, lungs, lymph nodes, skull bone, mandible, ribs, scapula, pelvis and Pott's spine, and thyroid.
