Cutaneous Tuberculosis: The Evolving Scenario

Multifocal Keloids Associated with Mycobacterium fortuitum following Intralesional Steroid Therapy

“…They are found ubiquitously in the environment including water, soil, dust, wild and domestic animals and fish. [8] They can grow in municipal water systems and distilled water. They are resistant to sterilizers, antiseptics, standard disinfectants including 10% povidine-iodine, 2% aqueous formaldehyde and 2% alkaline glutaraldehyde.…”

Tropical dermatology: Bacterial tropical diseases

“…84 Scrofuloderma results from contiguous involvement of the skin overlying another tuberculous process, usually tuberculous lymphadenitis or tuberculosis of bones and joints. 78,81 It may affect all age groups, although prevalence is greater among children, adolescents, and the aged. Scrofuloderma is the most common skin manifestation of tuberculosis in Brazil 82 and is common in most of the tropical countries of the New World.…”

“…The multidrug ''RIP'' treatment regimen involves use of rifampicin (10 mg/kg/d), isoniazid (5 mg/kg/d), and pyrazinamide (30 mg/kg/d) for at least 9 months. 77,78 Spontaneous healing in scrofuloderma does occur, but the course is protracted, and it may take years for scar tissue to completely replace the inflammatory and ulcerative lesions. 77 The typical scars facilitate a correct diagnosis, even after the process has become quiescent.…”

“…77,78 It can be transmitted through inhalation, ingestion, or direct inoculation to the skin. 79 The dermatologic manifestations are polymorphous and common worldwide, [79][80][81] both in temperate climates and in tropical areas.…”

Tuberculosis en patrón esporotricoide: una presentación inusual de tuberculosis cutánea en un paciente inmunocompetente

“…La tuberculosis cutánea es una forma poco común dentro de las presentaciones extrapulmonares, con una prevalencia cercana a 1,5%, entre todos los casos de tuberculosis extrapulmonar 3,4,5 . El agente etiológico es principalmente Mycobacterium tuberculosis, pero en algunos casos se encuentra Mycobacterium bovis, y menos frecuentemente el bacilo de Calmette-Guérin (BCG) 6 . La infección puede ser adquirida tras la inhalación, ingestión o inoculación del agente, y en la piel es capaz de inducir el desarrollo de granulomas, vasculitis o paniculitis 3 .…”
