[Painful muscle spasms of the trunk and upper limbs: tetanus or latrodectism? A case report]. / Spasmi dolorosi della muscolatura del tronco e degli arti superiori: tetano o latrodectismo? Presentazione di un caso clinico.

A clinical case of a young adult 23-years old is reported. The concomitant presence of tetanic symptoms and the anamnestic finding of a spider bite has made impossible a differential diagnosis of the pathology. The therapeutic approach, consisting in antibiotics and analgesics, is also reported. The administration of "antivenin" has not proven decisive to the resolution of the clinical picture. The diagnostic doubt has however represented a poorly influencing factor for a correct therapy.
