Malignant mesothelioma of the tunica vaginalis testis: one case report / 国际外科学杂志

ABSTRACT

Objective To study the clinical and pathological features, diagnosis and treatment of malig-nant mesothelioma of the tunica vaginalis testis. Methods One case of malignant mesothelioma of the tuni-ca vaginalis testis was reported. The patient was a 73 years old man, presented with a history of aggravated hydrocele for 1 year. B-ultrasound showed 7.5 cm×4.1 cm liquid anechoic area around the testis. The Pubmed and CBM databases were searched for related articles, and the clinical data were reviewed. Results An operation was performed to incise the tunica vaginalis. The pathology showed fecal caneeration in the tunica vaginalis testis and the immunohistology showed CK5/6, Calretinin and E-cadlberin positive. Right or-chiectomy was performed after three weeks. Local tumor recurrence and inguinal lymph nodes metastasis were found 11 months after operation, and local tumor and lymph nodes were resected. The tumor was diagnosed as malignant mesothelioma of the tunica vaginalis testis and CK5/6 and Calretinin fecal positive. Conclu-sions Malignant mesothelioma of the tunica vaginalis is a rare disease of the testis with potentially aggres-sive behavior. Due to the lack of tumor markers and characteristic symptoms, correct preoperative diagnosis is extremely difficult. Radical surgical treatment is of major importance to the survival of the patients. Life-long follow-up should be offered to patients with malignant mesothelioma of the tunica vaginalis.
