Abstract
We report here a case of malignant mesothelioma presenting as a perineal and intrascrotal mass. A 42-year-old Japanese male presented with an enlarging mass in the perineum and intrascrotum. Although the initial clinical diagnosis was perineal abscess, angiography revealed a tumor in the perineum and intrascrotum. The tumor was resected, and the pathological examination revealed malignant mesothelioma. Two months after the operation, a hard irregular mass with severe hemorrhage was noticed in the perineum, and was resected. A few weeks after the second operation local recurrence and, inguinal and intrapelvic retroperitoneal lymphadenopathy were found. Radiotherapy to recurrent sites was not effective. The patient died six months after the initiation of therapy. To our knowledge, 24 cases of malignant mesothelioma in the perineum or intrascrotum were reported in Japan and this case was thought to be the 25th case in Japan.
Glossary
- therapy
- any of the measures taken to treat a disease. Unproven therapy is any therapy that has not been scientifically tested and approved. Use of an unproven therapy instead of standard (proven) therapy is called alternative therapy. Some alternative therapies have dangerous or even life-threatening side effects. For others, the main danger is that a patient may lose the opportunity to benefit from standard therapy. Complementary therapy, on the other hand, refers to therapies used in addition to standard therapy. Some complementary therapies may help relieve certain symptoms of cancer, relieve side effects of standard cancer therapy, or improve a patient's sense of well-being. The ACS recommends that patients considering use of any alternative or complementary therapy discuss this with their health care team.
- recurrence
- cancer that has come back after treatment. Local recurrence is when the cancer comes back at the same place as the original cancer. Regional recurrence is when the cancer appears in the lymph nodes near the first site. Distant recurrence is when it appears in organs or tissues (such as the lungs, liver, bone marrow, or brain) farther from the original site than the regional lymph nodes. Metastasis means that the disease has recurred at a distant site.
- diagnosis
- identifying a disease by its signs or symptoms, and by using imaging procedures and laboratory findings. The earlier a diagnosis of cancer is made, the better the chance for long-term survival.
- tumor
- an abnormal lump or mass of tissue. Tumors can be benign (not cancerous) or malignant (cancerous).
- mesothelioma
- a tumor derived from mesothelial tissue, such as the peritoneum (lining the abdomen) or pleura (lining the lungs). More on mesothelioma.
