Abstract

A case of metastatic mesothelioma of the tunica vaginalis testis in a 57-year-old man is reported. Clinicopathological findings and treatment options are reviewed.

In plain English

This was a case report from the Lahey Clinic Medical Center, Burlington, Massachusetts, describing a 57-year-old man with malignant mesothelioma of the tunica vaginalis testis, the lining around the testis. He had no known occupational exposure to asbestos. He had earlier had mumps orchitis and removal of the right testis in 1986. He first had painless left scrotal swelling for 4 months, which was initially thought to be a hydrocele (a fluid collection). Surgery found bloody fluid and many small nodules on the testis. He then had the left testis and half of the scrotum removed, and pathologists judged the tumor to be malignant mesothelioma. Scans showed no spread. Surgical removal of lymph nodes at the back of the abdomen (retroperitoneal lymph node dissection) nevertheless found mesothelioma in 4 of 20 aortocaval lymph nodes. In March 1990, tumor consistent with mesothelioma was found in lymph nodes above the left collarbone, and chemotherapy was being given. The authors concluded that this dissection should be part of the surgical treatment and staging of this tumor. They noted that its rarity has limited experience in managing it.

What the study did and found

• Design: case report (single patient)
• Who was studied: One 57-year-old man referred to the Lahey Clinic Medical Center, Burlington, Massachusetts, after left radical orchiectomy had revealed malignant mesothelioma; he had a history of mumps orchitis and right orchiectomy in 1986
• Exposure: The patient had no known occupational exposure to asbestos; no fiber type or exposure was reported for him
• Main results:
  • The patient presented with painless left scrotal swelling lasting 4 months; the presumptive diagnosis was a noncommunicating hydrocele
  • Exploration through the scrotum found hemorrhagic fluid and numerous pink-tan nodules on the surface of the testis
  • CT of the abdomen and chest showed normal findings before re-exploration and left radical inguinal orchiectomy with hemiscrotectomy
  • Pathological review found features considered diagnostic for malignant mesothelioma
  • At retroperitoneal lymph node dissection no peritoneal studding was seen, but microscopic examination found metastatic malignant mesothelioma in 4 of 20 aortocaval lymph nodes
  • After the patient complained of a tender lump in the left neck on March 27, 1990, a biopsy of left supraclavicular nodes showed metastatic tumor consistent with mesothelioma, and chemotherapy was being given
• The authors' conclusion: The authors believed that retroperitoneal lymph node dissection should be included in the definitive surgical management and in the staging of malignant mesothelioma of the tunica vaginalis testis
• Limitations the authors state:
  • The authors stated that the rarity of this tumor has prevented investigators from building extensive experience in managing it
  • The authors stated that clinical follow-up data on their patient and on others are needed to clarify the role of prophylactic retroperitoneal lymph node dissection
