  • Introduction: Pyogenic arthritis, pyoderma gangrenosum, and acne (PAPA) syndrome is a rare autosomal dominant disease that usually presents in childhood with recurrent sterile arthritis. As the child ages into puberty, cutaneous features develop and arthritis subsides. We report the case of a now 25-year-old male patient with PAPA syndrome with the E250K mutation in PSTPIP1. We also present a systematic literature review of other PAPA cases.; Method: We conducted a literature search of PubMed using the following search terms: E250K mutation, PSTPIP1, and PAPA.; Results: PAPA syndrome is caused by mutations on chromosome 15q affecting the proline-serine-threonine phosphatase-interacting protein 1 (PSTPIP1) gene, also known as CD2-binding protein 1 (CD2BP1). The reported cases of PAPA syndrome currently in the literature involve mutations in A230T and E250Q. One case of a novel E250K mutation has been reported, which presented with a different phenotype to previously described cases of PAPA syndrome.; Conclusion: With variation present between disease presentations from case to case, it is possible that the spectrum of PAPA syndrome is wider than currently thought. Further research is needed which may uncover an as-yet undiscovered genetic abnormality linking these interrelated diseases together. (C) 2015 Elsevier Inc. All rights reserved.
