Cholinergic urticaria is a relatively common condition defined by itching, redness and whealing induced by exercise and passive warming. In turn, acquired idiopathic generalized anhidrosis is a rare disorder of unknown pathogenesis, characterized by an impairment in total body sweating despite exposure to heat or exercise. We report two cases of this extremely rare association of cholinergic urticaria and acquired generalized hypohidrosis, and briefly review current knowledge with regard to classification, ethiopathogenesis and therapeutic options.

Resumo: A síndrome de Kounis (SK) define‐se como a ocorrência simultânea de uma síndrome coronária aguda (SCA) e de um insulto anafilático ou alérgico. Resulta da desgranulação de mastócitos e subsequente libertação de mediadores inflamatórios, responsáveis pelo vasospasmo coronário ou rutura da placa de ateroma. O diagnóstico é clínico e baseia‐se na relação temporal entre os dois eventos. Apesar do número crescente de casos descritos, principalmente nos países do sul da Europa, o desconhecimento médico pode levar ao subdiagnóstico em Portugal. O reconhecimento da SK, mesmo realizado a posteriori, tem implicações clínicas, nomeadamente na investigação da atopia e medidas de dessensibilização, se possíveis, com vista à prevenção de novos eventos. Os autores relatam o caso clínico de um doente de 70 anos, que recorreu ao serviço de urgência por exantema generalizado e pruriginoso e iniciou dor torácica enquanto estava em observação. A angiografia confirmou SCA com evidência de doença coronária e subsequente diagnóstico de SK tipo II. Abstract: Kounis syndrome (KS) is the coincidental occurrence of acute coronary syndrome (ACS) and anaphylactic or allergic insult. It results from mast cell degranulation with subsequent release of numerous inflammatory mediators, leading to coronary vasospasm or atheromatous plaque rupture. Diagnosis is clinical and based on the temporal relationship between the two events. Despite the growing number of reported cases, especially in southern Europe, the lack of awareness of this association may lead to under‐reporting in Portugal. Recognition of KS, even if retrospective, has clinical implications since individual atopy must be investigated and desensitization measures should be employed, if possible, to prevent future events. We report the case of a 70‐year‐old man who was admitted to hospital because of generalized exanthema and itching and onset of chest pain while under observation. Coronary angiography confirmed coronary artery disease and ACS and he was diagnosed as having type II KS.
