The type of cutaneous infection varies mainly according to the patient's immune status, and the disseminated form is mostly found in the context of immunosuppression. We report the case of a 62-year-old male who was under long-term systemic corticosteroid therapy and presented with a 7-month history of multiple painless cutaneous lesions at various stages of development: papules, nodules, pustules and hemorrhagic crusts, as well as small erosions and ulcers distributed over the limbs and scalp. Cutaneous biopsy showed a suppurative granulomatous infiltrate with abscess formation. Fite stain revealed numerous extracellular bacilli, suggesting mycobacterial infection, particularly by atypical mycobacteria. Culture of a skin sample revealed <i>Mycobacterium chelonae</i>. The patient started multidrug therapy and showed clinical improvement despite of resistance to one of the antibiotics. This striking presentation underlines the role of immunosuppression with corticotherapy as a major risk factor for these infections. Multidrug therapy is advised and antibiogram is essential in directing treatment.
