Pott's puffy tumour in an immunosuppressed adult: case report and systematic review of literature

This case is of a 34-year-old immunocompromised male with Pott's puffy tumour, which was treated with antibiotics and endoscopic sinus surgery. Pott's puffy tumour is typically a complication of frontal sinusitis in children and immunocompromise can be a precipitating factor. A search was conducted of Embase, Medline, CINAHL, Cochrane, Google Scholar, Informit and Scopus of 'Pott's Puffy' and variations of this phrase. Initial 804 records were reviewed by title, abstract and full text. Of the unique papers identified, 155 only included paediatric patients and 128 included adult patients. After title, abstract and full-text review of 13 papers were identified describing Pott's puffy tumour in immunocompromised patients. Immunosuppression was noted as a risk factor in only a small number of cases, with diabetes mellitus being the most common. A few cases did note immunosuppression due to newer immunomodulatory agents being used for treatment of autoimmune conditions.
