First reported case of adult paratesticular myxofibrosarcoma in Indonesia: Case report and literature review

INTRODUCTION AND IMPORTANCE

Myxofibrosarcoma is one of the rarest sarcoma types, found in para-testicular regions of the elderly. Although this tumor is detectable by MRI, there has been no specific guideline for managing its recurrence.

CASE PRESENTATION

A 49-year-old male with a painless scrotal mass was studied. The patient had no other complaint, and the laboratory results showed unremarkable testicular tumor markers. Ultrasound examination of the right hemiscrotum shows a solid mass in the scrotum and right inguinal that compressed the right hemitesticle. MRI examination of the scrotal region revealed a homogeneous solid mass, while at the lower abdomen, it showed a mass extending from the inguinal canal to the penis shaft and right testis. The patient had no signs of metastatic disease, but after high ligation orchidectomy, a rare paratesticular myxofibrosarcoma was revealed from histopathology examination.

CLINICAL DISCUSSION

Based on existing data and patient MRI imaging, total surgical excision with high ligation orchidectomy is the only curative therapeutic option for low-grade tumors. Furthermore, no recurrent mass was identified during follow-up, and adjuvant chemotherapy or radiotherapy was not administered. The patient was satisfied with the surgery and is on a 6-month routine follow-up to observe the physical symptoms.

CONCLUSION

This is the first adult paratesticular myxofibrosarcoma case in Indonesia, and it was performed with radical orchidectomy with high ligation due to its invasiveness. However, adjuvant chemotherapy was not provided because the benefit remained inconclusive. The result showed that this approach produces excellent outcome without any relapse.

Splenogonadal fusion: aiding detection and avoiding radical orchidectomy

Splenogonadal fusion is a rare benign congenital anomaly in which there is an abnormal connection between the gonad and the spleen. It was first described over 100 years ago with limited reports in the literature since then. Its similarity in presentation to testicular neoplasia poses a significant challenge in diagnosis and management, often resulting in radical orchidectomy. We present the case of a 31-year-old man who presented with a rapidly growing left-sided testicular mass and suspicious ultrasound findings; histology from the subsequent radical inguinal orchidectomy showed findings consistent with splenogonadal fusion. We describe points for consideration in the clinical history, examination and imaging that could suggest splenogonadal fusion, including preoperative technetium-99m-sulfur colloid imaging and intraoperative frozen section evaluation, which may confirm the diagnosis and prevent unnecessary orchidectomy.
