Mycobacterium Chelonae Infection of the Buttocks Secondary to Lipofilling: A Case Report and Review of the Literature

Mycobacterium chelonae is a nontuberculous mycobacterium, classified as a Runyon type IV mycobacterium. In relation to humans, it is most commonly associated with tissue trauma or pulmonary infections. The majority of medical reports describe finding M. chelonae in the surgical setting, attributing infection to inadequate sterilization of surgical equipment. Symptoms are often nonspecific and include pain, erythema, and draining subcutaneous nodules and skin lesions. Therefore, the diagnosis of M. chelonae is often difficult to establish without prior suspicion of the disease, but can be confirmed with culture. We will describe the case of a 40-year-old female who contracted M. chelonae infection of the buttocks after abdominal liposuction and gluteal fat injection. We will describe her symptomatology, diagnosis, and successful treatment with surgical excision and antibiotics.
