Timely Surgical Resection Achieved Prolonged Remission in Patients With Malignant Mesothelioma of the Tunica Vaginalis Testis and Retroperitoneal Recurrence.

Abstract

Malignant mesothelioma of the tunica vaginalis testis (MMTVT) is a rare tumor of the testicular sheath. More than 50% of cases initially present as recurrent hydrocele, but there have also been documented cases with hematocele, inguinal hernia, or epididymitis. Due to the non-specific symptoms and signs of the disease, it is almost always diagnosed intra- or postoperatively. The lack of standardized therapy protocols, as well as the lack of evidence supporting systemic chemotherapy, have fueled arguments in favor of the necessity of retroperitoneal lymph node dissection (RPLND) in the treatment of the disease, especially in the case of lymph node metastasis. We present a case of MMTVT achieving prolonged remission after timely and extensive surgical treatment.
