Spermatocytic tumor: A rare case report

BACKGROUND

Spermatocytic tumor is a rare, malignant neoplasm of the testes. Since the prognosis for this tumor type is favorable, accurate diagnosis and differentiation from other malignant testicular neoplasms (classic seminoma and lymphoma) are crucial. To add to the existing literature on the diagnosis of spermatocytic tumor, herein we report the detailed clinical and histopathologic findings for a case that we encountered.

CASE SUMMARY

A 60-year-old Chinese man presented with a solid mass in the right scrotum. The mass was surgically removed and spermatocytic tumor was diagnosed. On microscopy, the tumor cells displayed an unusual arrangement in lobules, presenting a pseudo-glandular appearance. To summarize and compare the diagnostic features of this tumor and those of the differential diagnoses, we report our case findings and those mentioned in the literature for various testicular tumors. Although imaging methods can detect masses early in development, their diagnostic capabilities are limited. Biopsy, histopathology, and immunohistochemistry are necessary for confirmatory diagnosis.

CONCLUSION

It is important to identify and review the key diagnostic features of spermatocytic tumor.

Testicular Cancer: Epidemiology, Diagnosis, and Management

There were an estimated 8720 new cases of testicular cancer (TC) in the United States in 2016. The cause of the disease is complex, with several environmental and genetic risk factors. Although rare, the incidence has been steadily increasing. Fortunately, substantial advances in treatment have occurred over the last few decades, making TC one of the most curable malignancies. However, because TC typically occurs in younger men, considerations of the treatment impact on fertility, quality of life, and long-term toxicity are paramount; an individualized approach must be taken with patients based on their clinical and pathologic findings.
