Abstract
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.

Keywords: Spermatocytic tumor; Germ cell tumor; Immunohistochemistry; Pseudo-glandular; Case report

Core Tip: Spermatocytic tumor is a rare malignant testicular tumor. At present, there are few reported cases in the world. The understanding of clinicians and pathologists about this disease is not comprehensive enough. Here we report a case of spermatocytic tumor, emphasizing the morphological features of spermatocytic tumor and the key points of differentiation from classic seminoma and lymphoma, so as to avoid misdiagnosis.
