The aim of this study is to review sirolimus as a treatment for blue rubber bleb naevus syndrome (BRBNS). A literature search of Medline, Embase, CINAHL, SCOPUS and Google Scholar was conducted for publications reporting treatment of patients with BRBNS with sirolimus. Of 46 articles identified, 17 studies reporting 23 patients met inclusion criteria. Sirolimus was well tolerated in all but one patient who required treatment cessation; 17/18 patients noted an improvement in gastrointestinal disease where this was reported; 21/22 patients noted an improvement in cutaneous disease where this was reported. Based on these results, sirolimus may be considered a first-line treatment of BRBNS depending on patient morbidity.

Mammalian meat allergy is an allergic reaction mediated by IgE antibodies directed against the mammalian oligosaccharide epitope galactose-α-1,3-galactose. Clinically, it is characterized by a range of symptoms including urticaria, angioedema, gastroenteritis, and anaphylaxis hours following ingestion of red meat. It is an emergent allergy in tick endemic areas across the world. As a recently described disease with a cutaneous presentation, dermatologists should be familiar with this entity and recognize it as a differential diagnosis for urticarial and anaphylaxis reactions.
