動脈硬化症が原因と考えられた精巣区域性梗塞

A case of testicular segmental infarction due to arteriosclerosis

　症例は55歳，男性。基礎疾患はなく，喫煙歴35年。右陰囊部痛を主訴に2002年3月に来院した。触診と超音波検査の結果，精巣内の出血性梗塞が考えられたが精巣悪性腫瘍を否定できず，右高位除睾術を施行した。病理の結果は，動脈硬化症が原因と考えられる精巣区域性梗塞であった。術後は禁煙とし，血小板凝集抑制剤の内服にて予防治療しているが，現時点では対側の精巣は異常所見を認めていない。

　Testicular segmental infarction is a comparatively rare disease because there are two or more nutrition blood vessels of a testis,while whole testicular infarctions are frequently resulted from torsion of spermatic cord. The patient is a 55 year-old man,without any particular past history except 35 years'smoking history. He visited our hospital with right scrotum pain in March 2002. Testicular infarction was suepected by the palpation and the ultrasound examinations but a testicular malignant tumor could not be denied. Therefore right high orchiectomy was performed. The pathology showed testicular infarction due to arteriosclerosis. After the operation prohibition of smoking and use of an anti-platelet aggregation inhibitive drug were given.
