Background: Members of Micobacterium. abscessus complex comprises three subspecies (M. abscessus subsp. Abscessus, M. abscessus subsp. Bolletii, and M. abscessus subsp. Massiliense) and are a rapid-growing nontuberculous mycobacteria present in different aquatic habitats and soil. It often causes a wide spectrum of infections involving pulmonary infections, surgical wound infections, and infections related to mesotherapy, catheters, hemodialysis devices, endocarditis, and disseminated infections in immunocompromised individuals. Methods: In this article we comment on the most relevant aspects of nine patients with skin lesions caused by M. abscessus subsp. massiliense infection. Clinical characteristics, histopathology, and molecular identification were performed. Results: The patients in the clinical cases presented a history of trauma, tattoos, and physical therapy techniques. The most common treatments were minocycline and clindamycin, doxycycline, ceftriaxone, cephalexin, moxifloxacin, rifampicin, and trimethoprim-sulfamethoxazole. The evolution of the treated patients was acceptable, except for one patient, who showed a partial improvement. M. massiliense were identified in all clinical cases using a species-specific PCR. Conclusion: Our series consisted of nine cases of skin biopsies recorded in different years; for this reason, we do not have all the data necessary for a complete description, in particular in four cases, causing limitations in the manuscript, especially in the therapy used and the evolution of patients due to lack of follow-up.
