RESUMEN
Mammomonogamus laryngeus (sin.: Syngamus laryngeus) is a nematode which parasites the respiratory tract of some animals. It is occasionally seen in humans, who present symptoms similar to other diseases with respiratory manifestations, such as a chronic dry cough and chest pain, in addition to a "foreign body" sensation in the throat. It can be diagnosed through rhinolaryngoscopy or bronchoscopy examinations, but this often occurs only after spontaneous expectoration of the worms, a long period of symptomatology and the use of several types of medication.

The patient consulted several health professionals during the course of the disease and was prescribed numerous drugs. Diagnosis was eventually reached after the spontaneous expectoration of a nematode couple
