Cutaneous tuberculosis in Rio de Janeiro, Brazil: description of a series of 75 cases

“…Our group tend to regard a granulomatous lobular or septolobular panniculitis (with or without vasculitis) in the setting of a clinical, epidemiological, and/or microbiological diagnosis of tuberculosis as EIB, which was an important clinical form in our study. It is the most frequent clinical form of CTB in China, Hong Kong, Japan, and even in Rio de Janeiro, Brazil . Another reference hospital also in the city of Rio de Janeiro found 26 cases of CTB in 14 years .…”

“…11 Women predominated in our case series, as described in other studies of CTB. 9,[12][13][14][15] node is the most common presentation of CTB described in the literature in some developing countries. [22][23][24] Similarly, gumma, known as cutaneous abscesses, is also found in large case series of CTB.…”

“…10 Overall, the studies highlight the predominance of women in this form of presentation. 10,15,18,50 The detection of mycobacteria can be based on identification of genetic material by PCR technique, searching for mycobacterial antigens or fragments, with a positivity of 14-80%. [51][52][53][54][55][56][57][58][59] In our center, this technique is not standardized to CTB.…”
