Sperm granuloma is a rare disease in clinical andrology and its incidence is still unclear worldwide. According to the existing literature, sperm granuloma often occurs unilaterally. Clinical and ultrasound features are similar to epididymal tuberculosis, chronic epididymitis and other diseases. Sperm granuloma is usually diagnosed based on postoperative histopathological and immunohistochemical examination.
A 46-year-old man was admitted to the hospital due to the presence of a left scrotal mass for 3 mo and aggravation of pain for 1 wk. The lesions at both sites were surgically resected. Postoperative pathological examination showed that the left spermatic cord mass and the right epididymal mass were consistent with sperm granuloma. The sperm granulomas then recurred 3 mo after surgery. There is little change in the local mass so far.
The case report is helpful for our understanding of this disease. In clinical diagnosis, it should be distinguished from epididymal tuberculosis, chronic epididymitis and other diseases. Color Doppler ultrasound can be used as a preferred examination method but postoperative pathological examination is still needed for diagnosis.
Core Tip: We reported on a rare case of sperm granuloma which occurred bilaterally in the left spermatic cord and on the right epididymis. Remarkably, the granuloma recurred at 3 mo after surgery and this recurrence has not been reported before. Since the patient has no history of vasectomy, tumor or trauma, it is more likely that this case of sperm granuloma is merely caused by inflammation which is rare for sperm granuloma. This case report can greatly enhance our understanding of sperm granuloma and it is helpful for differential diagnosis of various epididymal lesions in clinical practice.
