Summary of the article

The authors reported a case of malignant mesothelioma of the tunica vaginalis testis, the membrane around the testis, in a man with possible occupational asbestos exposure. A 45-year-old white man who had worked in an electrical power plant developed a painless mass in the right testicle. He was first treated for presumed epididymitis, but the mass did not shrink over 2 weeks. Ultrasound confirmed a solid mass, and blood levels of the tumour markers AFP and HCG were normal. A biopsy was first reported as an 'adenomatoid tumour', but a second pathologist raised the possibility of malignant mesothelioma. Review at Massachusetts General Hospital confirmed malignant mesothelioma of the epithelial subtype. The right testis was removed through the groin. The tumour involved the cremasteric muscle and the lower spermatic cord. All margins were free of tumour, and no vascular or lymphatic invasion was seen. CT and lymphangiography showed no spread. Follow-up examinations and tumour marker tests showed no recurrence over 12 years. The patient reported exposure to asbestos in insulation materials, but this could not be further documented. The authors noted that about 40 such cases had been reported since 1957, some with asbestos exposure and latent periods of 8 to 40 years. They concluded that scrotal masses need careful and prompt evaluation, and that this tumour should be considered particularly in patients with known asbestos exposure.

In plain English

This case report described a single patient, so it shows what happened to one person, not a rate of disease. A 45-year-old white male who had worked in an electrical power plant for most of his career developed a painless mass in his right testicle. He reported exposure to asbestos in insulation materials, but the authors stated that further documentation of exposure was unavailable, and they called the exposure possible. A first biopsy was reported as an adenomatoid tumour. A second pathologist raised the possibility of malignant mesothelioma, and further review at Massachusetts General Hospital confirmed malignant mesothelioma of the epithelial subtype. Removal of the right testicle showed the tumour in the tunica vaginalis, extending to the cremasteric muscle and lower spermatic cord, with all resection margins free of tumour. Scans showed no spread, and there was no evidence of recurrent disease over 12 years. The authors concluded that mesothelioma of the tunica vaginalis should be considered when evaluating scrotal masses, particularly in patients with known asbestos exposure.

What the study did and found

• Design: case report (one patient)
• Who was studied: One 45-year-old white male, previously employed as an electrical power plant worker, referred to Massachusetts General Hospital, Boston, USA
• Exposure: Self-reported exposure to asbestos in insulation materials while employed in an electrical power plant for most of his career. No fiber type was given and the exposure was not documented further.
• Main results:
  • The first biopsy was reported as an adenomatoid tumour. A second pathologist raised the possibility of malignant mesothelioma, and further review confirmed malignant mesothelioma of the epithelial subtype.
  • Right inguinal orchidectomy showed malignant mesothelioma of the tunica vaginalis involving the cremasteric muscle and lower spermatic cord. All resection margins were free of tumour, and no vascular or lymphatic invasion was noted.
  • Abdominal and pelvic CT and a bipedal lymphangiogram showed no evidence of metastatic disease.
  • The patient had no evidence of recurrent disease over 12 years of follow-up.
  • Blood tumour markers alpha-fetoprotein (AFP) and human chorionic gonadotropin (HCG) were within normal limits.
• The authors' conclusion: The authors concluded that the case highlights the need for careful and prompt evaluation of scrotal masses. Although rare, mesothelioma of the tunica vaginalis should be considered in the differential diagnosis, particularly in patients with known asbestos exposure. They added that tumours confined to the testicle may be curable with surgery.
• Limitations the authors state:
  • The asbestos exposure was reported by the patient and could not be documented further. The authors described it only as possible.
