A 57-year-old male patient receiving peritoneal dialysis (PD) was referred to the urology department with painless scrotal swelling. He had no history of genital trauma, but aspirin and clopidogrel had been prescribed for coronary artery disease. A non-tender and firm mass with smooth surface was palpable in the right scrotum. Testicular cancer was suspected by the results of ultrasonography and computed tomography (Fig. 1). The patient, thus, underwent right high inguinal orchiectomy. Unexpectedly, no malignant cells were found in pathological examination (Fig. 2). The diagnosis was hematocele.

a Scrotal ultrasonography showed a 100-mm mass filled with heterogeneous hypo- to iso-echoic component. b Computed tomography showed a large mass with homogenous low attenuation surrounded by smooth capsule

Microscopic examination revealed that the cystic mass was surrounded by dense fibrous capsule, and contained only red blood cells trapped by fibrin threads
