[Purulent lymphadenitis after peritonsillar abscess under immunosuppression. An often forgotten differential diagnosis]. / Eitrige Lymphadenitis nach Abszesstonsillektomie bei Immunsuppression. Eine oft vergessene Differenzialdiagnose.

In the present case study, a 75-year-old, immunosuppressed man presented with recurrent cervical abscesses after a peritonsillar abscess. In the cervical region, an ulcer developed with persistent wound healing deficit. Subsequently, the patient's general condition deteriorated, showing symptoms of a Landouzy sepsis. In the course of the examination, Mycobacteria tuberculosis was detected in the cervical ulcer. He suffered from latent tuberculosis, which was reactivated by a combination of his disease, immunosuppressive therapy and the preceding peritonsillar abscess. Upon treatment with tuberculostatics, the patient fully recovered.
