Chronic cough and haemoptysis due to a nematode, "Syngamus laryngeus"

Primeira descrição de singamose brônquica ocorrida no Estado do Espírito Santo

Relatamos o caso de um homem de 48 anos, que evoluiu durante 4 meses com quadro de tosse seca associada à dor torácica. Após serem descartadas as etiologias mais prováveis, realizou-se uma broncofibroscopia que revelou a presença de um casal de Syngamus laringeus no brônquio do lobo superior esquerdo. O paciente tornou-se assintomático após a retirada do nematóide.

Case report of and description of parasite in Mammomonogamus laryngeus (human syngamosis) infection

About 100 cases of human infections with Mammomonogamus laryngeus (Syngamidae, Syngaminae) have been reported, with virtually all cases originating in the Caribbean Islands and Brazil. This report describes the fifth patient in North America infected with M. laryngeus and the first case documented to originate in Jamaica. The patient complained of a characteristic persistent nonproductive cough and a lump in her throat. M. laryngeus is a nematode in which the male and female are permanently joined in copula, producing a distinctive Y shape. Since there is scant clinical information about this parasite, this report includes a description of the adult worms and eggs, a summary of the epidemiology, and the clinical manifestations in humans. Illustrations are presented to facilitate future identification of this parasite and to expedite treatment.

Syngamosis: two new Brazilian cases and evidence of a possible pulmonary cycle

Cases of syngamosis due to Mammomanogamus laryngeus are reported, with a discussion of diagnostic aspects. A pulmonary cycle for M. laryngeus is proposed, suggested by the appearance of a transient area of homogeneous consolidation of the lung, detected by X-ray.
