[A case of idiopathic chronic scrotal hematocele]

A case of chronic scrotal hematocele is reported. A 63-year-old male first noticed the painless swelling of his left scrotal contents about 30 years before he visited our clinic on September 16, 1987. Examination revealed a hard mass, 10 x 8 cm in diameter, in the left scrotum. The scrotum did not transmit light. Since it was impossible to exclude testicular tumor completely, we performed left high orchiectomy. The extracted mass contained old brownish black clotted blood and a normal testis. Histopathological examination revealed that the hematocele showed a dense, fibrous wall with hyalinization. Six cases of chronic scrotal hematocele including our case have been reported in the Japanese literature.
