Background: Myoid gonadal stromal tumors (MGST) of the testis represent a very rare finding. They are an emerging clinicopathological entity with specific features and identity. Nowadays, pathological recognition and diagnosis of MGSTs still represents a difficult challenge in most cases and there are no data of specific radiological features of these tumors expect for what seen by ultrasound; besides a conservative surgical approach was never performed to treat these lesions.Case Description: We present the case of a 20-year-old young man patient with symptoms suspicious for left varicocele, who was incidentally diagnosed with right testicular nodule via scrotal doppler ultrasound powered with contrast enhancement infusion and subsequent multiparametric magnetic resonance imaging. Then, lesion was treated through a testis sparing surgical approach. Histopathology, which included an external revision by an experienced Center, revealed a MGST with benign features, so that no further treatment was considered. 3 and 12 months after surgery a contrast enhancement ultrasound was performed with no evidence of recurrence.Conclusions: Previous reported cases of MGST were all difficult to characterize as a specific pathological entity; treatment usually applied was radical orchiectomy and a subsequent total Body CT was performed for staging purpose. No metastatic spreading nor recurrence were ever reported. Considering the favorable behavior of this pathologic entity, testis-sparing surgery with no radiation exposure during follow-up is a safe and effective strategy.

Abstract

Background: Myoid gonadal stromal tumors (MGST) of the testis represent a very rare finding. They are an emerging clinicopathological entity with specific features and identity. Nowadays, pathological recognition and diagnosis of MGSTs still represents a difficult challenge in most cases and there are no data of specific radiological features of these tumors expect for what seen by ultrasound; besides a conservative surgical approach was never performed to treat these lesions.Case Description: We present the case of a 20-year-old young man patient with symptoms suspicious for left varicocele, who was incidentally diagnosed with right testicular nodule via scrotal doppler ultrasound powered with contrast enhancement infusion and subsequent multiparametric magnetic resonance imaging. Then, lesion was treated through a testis sparing surgical approach. Histopathology, which included an external revision by an experienced Center, revealed a MGST with benign features, so that no further treatment was considered. 3 and 12 months after surgery a contrast enhancement ultrasound was performed with no evidence of recurrence.Conclusions: Previous reported cases of MGST were all difficult to characterize as a specific pathological entity; treatment usually applied was radical orchiectomy and a subsequent total Body CT was performed for staging purpose. No metastatic spreading nor recurrence were ever reported. Considering the favorable behavior of this pathologic entity, testis-sparing surgery with no radiation exposure during follow-up is a safe and effective strategy.
