Abstract:
The use of aesthetic procedures that improve body image is constantly growing, as well as infections associated with them, such as atypical mycobacteriosis. Mesotherapy is a minimally invasive aesthetic procedure that consists of the application of substances that seek to stimulate the dermis and subcutaneous cellular tissue, for the treatment of cellulite and skin rejuvenation. We report a case of mycobacterial infection after mesotherapy in the buttocks and thighs that appeared as subcutaneous abscesses, they responded satisfactorily to prolonged antibiotic treatment with clarithromycin and trimethoprim-sulfamethoxazole. Infections associated with mesotherapy have been reported in Spain, Latin America and the Caribbean, all possibly related to lack of health controls. We emphasize the importance of being aware of these infectious complications and the need to reinforce the necessary security measures to avoid them.
