Disseminated Mycobacterium genavense infection in a patient with immunosuppressive therapy and lymphoproliferative malignancy.

We present the case of a 51-year-old woman who presented a right supraclavicular mass corresponding to lymphadenitis with atypical mycobacterium (Mycobacterium genavense). Later, she developed subcutaneous purulent small nodules containing the same germ. The presence of this mycobacterium was in the context of recurrent peripheral T-cell lymphoma and immunosuppressive therapy for seronegative inflammatory polyarthritis.
