[Lemierre syndrome].

Lemierre's syndrome is a rare and severe condition, with a primary focus in the cervicofacial area and followed by thrombosis of the internal jugular vein and metastatic infections, most often pulmonary. The principal pathogen is Fusobacterium necrophorum. Less rare and associated with high mortality before antibiotics, Lemierre syndrome had became exceptional until the increase in the number of cases in recent years.

Lemierre syndrome: once seen it can never be mistaken.

Lemierre syndrome is a rare but severe septicaemia due most frequently to Fusobacterium necrophorum, with primary foci in the head, internal jugular vein thrombosis and metastatic infections, mainly in the lungs. We report two cases of Lemierre syndrome admitted to the paediatric unit of our hospital at 2-month intervals. The first was 10 years old and the second one was a 3-month-old infant.
