Malignant mesenchymoma of median nerve: combined nerve sheath sarcoma and liposarcoma.

A malignant mesenchymoma consisting of nerve sheath sarcoma and liposarcoma occurred in the right median nerve of a 29-year-old man who did not have stigmata of von Recklinghausen neurofibromatosis. It produced pain at the affected part, referred pain to the palm, and weakness of muscles supplied by branches of this nerve. The tumor was first excised 1 month after its initial manifestation, but recurred twice and eventually metastasized to the lung within 19 months. It is suggested that aberrant differentiation of the mesenchymal component of the neural crest, the ectomesenchymal structure, has created this combined sarcoma of nerve sheath and liposarcoma, forming a malignant mesenchymoma.

Combined paraganglioma and glioma of conus medullaris and cauda equina.

A mixed paraganglioma and glioma occurred in the conus medullaris and cauda equina of a woman. The tumor was subdural, encapsulated, and vascular. It was first manifested with symptoms and signs of compression of the cauda equina when she was 19 years of age and was excised when she was 24. The tumor was attached to the conus medullaris, the dura mater, and a nerve root of the cauda equina. Striking light and dark cells with an organoid arrangement mingled with a few glial fibrillary acidic protein (GFAP)-positive neuroglia forming a combined paraganglioma and glioma. Twenty-three paragangliomas were reported in the literature including the present case. The sex and age of recorded 19 patients demonstrated ten males and nine females with an average age of 46.3 years. Twenty tumors were subdurally situated at the conus medullaris and cauda equina. Three neoplasms were epidural and thoracic in location.

Malignant neoplasm of mixed mesenchymal and neuroepithelial origin (ectomesenchymoma) of thigh.

A 49-year-old man had a malignant soft tissue tumor of the right thigh with metastasis to the femoral region and lower quadrant of the anterior abdominal wall on the right side and the left supraclavicular lymph nodes. The neoplasm showed features of chondrosarcoma and primitive neuroectodermal tumor (combined neuroblastoma, ependymoma, astrocytoma, and oligodendroglioma). The gliomatous part of the mixed tumor was confirmed by identification of the glial fibrillary acidic protein (GFAP). The diverse cellular population suggests a tumor origin from the ectomesenchymal remnant of the neural crest. The mesenchymal component of the neural crest would differentiate into the chondrosarcoma and the neuroectodermal component into the primitive neuroectodermal neoplasm. These various neoplastic elements, then, would form a neoplasm of mixed mesenchymal and neuroepithelial origin or an ectomesenchymoma.

Solitary primary intracranial extracerebral glioma. Case report.

A case is presented of a solitary primary extracerebral mixed glioma occurring in the right suprasellar and parasellar region of a 49-year-old woman who had bilateral temporal hemianopsia for 3 months. At craniotomy, the well demarcated outline and extracerebral location of the tumor suggested that it was a meningioma. However, its gliomatous nature was confirmed by identification of glial fibrillary acidic protein (GFAP) in the tumor cells. Review of nine reported solitary primary intracranial extracerebral gliomas, including the present case, revealed that they tended to occur in the third to fifth decades of life, in patients with an average age of 42 1/2 years, and without sexual predilection. All were supratentorial with a tendency to be situated in the vicinity of the Sylvian fissure. Only the glioma in the present case was at the cranial base. They were diagnosed as three astrocytomas, two glioblastomas, two oligodendrogliomas, one astroblastoma, and one mixed glioma. A suggestion is made that all these gliomas arose primarily from heterotopic neuroglia in the leptomeninges.

Metastasis of bronchogenic adenocarcinoma to renal adenocarcinoma.

Metastasis of bronchogenic adenocarcinoma to renal adenocarcinoma occurred in a 79-year-old woman. The bronchogenic adenocarcinoma metastasized widely to various organs, whereas the renal adenocarcinoma was nonmetastatic. This case brings the total reported number of cancer-to-cancer metastases to 37. Renal adenocarcinoma was the recipient in 24, and bronchogenic carcinomas comprised one half of all donor cancers.

Cerebellar neoplasm of mixed mesenchymal and neuroepithelial origin. Case report.

A 3 1/2-year-old boy had a neoplasm of mixed mesenchymal and neuroepithelial origin in the cerebellar vermis. The tumor was composed of rhabdomyosarcoma and medulloblastoma. There was additional differentiation within the neuroepithelium, including neoplastic neurons, neuroblasts, astroglia, oligodendroglia, ependymal cells as well as foci of glioblastomatous transformation. It is suggested that this combined tumor arose from the neural crest or combined neural crest and neural tube. The rhabdomyosarcoma could have arisen from the mesenchymal portion of the neural crest, and the medulloblastoma from the neuroectodermal part of the neural crest or from the neural tube itself. The two tumor types formed a neoplasm of mixed mesenchymal and neuroepithelial origin.
