The case report of a 26 years patient, assisted in the Hospital of the Ecuadorian Institute for Social Security of Ibarra city, after being bitten by a spider of the Cyclosternum sp gender and of the Theraphosidae family is described. The main characteristic of the clinical pattern was a decrease of platelets values in 29%. He was treated with intravenous hydrocortisone and 5 weeks later the platelets reached their initial value. The relevance of the case is given by the infrequent of this reaction as a result of the bite of this spider species.
