Telangiectasia macularis eruptiva perstans presented as a pseudoallergic food reaction.
Telangiectasia macularis eruptiva perstans (TMEP) is a rare form of cutaneous mastocytosis observed in less than 1% of cases of mastocytosis. Clinically, anaphylaxis may appear as a result of increased mast cell degranulation in different circumstances. A case of TMEP presented as pseudoallergic reactions to foods is reported in which the appearance of typical lesions on the trunk and their histological analysis together with a negative food allergy study confirmed the diagnosis.
