M2-Polarized Macrophages Compose Lupus Vulgaris Arising from a Bacillus Calmette-Guérin Vaccination Site

چکیده
Since bacillus Calmette-Guérin (BCG) is an attenuated strain of Mycobacterium bovis, lupus vulgaris (LV) is reported as one of the rare complications after BCG vaccination, correlating with immunosuppression in the lesional skin. In this report, we describe a case of LV arising from the BCG vaccination site 22 years after vaccination. Interestingly, in the present case, granuloma cells were composed of M2-polarized macrophages. Our case might explain the contribution of M2-polarized macrophages to the biology of LV arising from a BCG vaccination site.

Disseminated Bacillus Calmette-Guérin Disease after BCG Vaccination: A Case Report from China
Background: Bacillus Calmette-Guérin (BCG) vaccination is recommended for newborn infants worldwide to prevent tuberculosis. However, complications do occur inevitably in a very low rate, among which the most serious is disseminated disease. The disseminated bacillus Calmette–Guérin disease is a rare disease with high fatality, and can be seen among persons with an underlying immunodeficiency. ...

Introduction: Lupus vulgaris is the most common form of cutaneous tuberculosis caused by contiguous spread from an underlying infective focus or lymphatic or hematogenous spread. It can also develop at the site of direct inoculation (e.g., tattooing and ear piercing) or Bacillus Calmette-Guerin vaccination. The solitary involvement of the pinna is rare and may face clinicians with a diagn...

Intralesional Mycobacterium bovis bacillus Calmette-Guérin (BCG) has long been a relatively inexpensive therapy for inoperable cutaneous metastatic melanoma (CMM), although intralesional BCG skin mechanisms remain understudied. We analyzed intralesional BCG-treated CMM lesions combined with in vitro studies to further investigate BCG-altered pathways. Since macrophages play a pivotal role again...
