Tuberculous gumma is a skin condition characterized histologically by massive necrosis. [1] Restated, this is a skin condition that results from hematogenous dissemination of mycobacteria from a primary focus, resulting in firm, nontender erythematous nodules that …

Acute verrucosa TB and TB gumma occur by hematogenous spread. Scrofuloderma spreads from underlying structures, while self-inoculation from the gastrointestinal tract can result in orificial TB. 38 Exogenous TB refers to that acquired by inoculation and classically includes tuberculous chancre and TB verrucosa cutis.

Tuberculous gummas are an unusual form of tuberculosis (TB) accounting for 1%-2% of all cutaneous TB cases. The aim of this article was to describe the epidemiological, clinical, bacteriological, immunological, and therapeutic features of this form upon a case report and a literature review.

Tuberculous gumma is a form of cutaneous TB caused by haematogenous dissemination of M tuberculosis. Clinically, it is difficult to differentiate this form from other pyogenic infections such as syphilis, pyoderma gangrenosum, atypical mycobacterial lesions and some fungal infections.

Metastatic TB abscesses (TB gumma) can arise from breakdown of an old healed tubercle that still contains live organisms or from cell-mediated immune defense inhibition that reactivates. 1,3 TB gumma is usually seen in malnourished children and immunosuppressed adults. 5 Single or multiple nontender, fluctuant nodules develop forming draining ...

Tuberculous gumma, also called metastatic tuberculous abscess, originates from hematogenous spread especially in periods in which there is decreased cellular immunity. Typically, it affects malnourished children and immunocompromised adults, with rare reports in immunocompetent patients. 22 , 38 Tuberculous abscesses have also been described in ...
