[Scrotal hematoma associated with idiopathic thrombocytosis: a case report]

We report a case of acute scrotal hematoma associated with idiopathic thrombocytosis. A 75-year-old man visited our hospital for the treatment of a left scrotal mass that had been increasing in size; the mass had developed after the puncture of left testicular hydrocele. The patient was diagnosed with acute scrotal hematoma on the basis of ultrasonography findings. The patient underwent an emergency operation for the removal of the hematoma. On 2 days after the surgery we noticed an increase in the size of the hematoma. The patient had a 4-year clinical history of idiopathic thrombocytosis for which he had not received any treatment. Although the platelet count was slightly high at the time of the operation, complete hemostasis did not occur because of the existence of platelet dysfunction. The second hematoma was treated conservatively. To our knowledge, this is the first case report on the acute scrotal hematoma associated with idiopathic thrombocytosis.
