Ghost cell tumors are a family of lesions that range in presentation from cyst to solid neoplasm and in behavior from benign to locally aggressive or metastatic. All are characterized by the presence of ameloblastic epithelium, ghost cells, and calcifications.

The category of germ cell tumors includes a broad array of histologic subtypes ranging from the benign, mature teratoma to the primitive, aggressive embryonal carcinoma (Box 1). These tumors share their origin in a primordial germ cell with multipotent capacity for differentiation along a variety of pathways.

Invasion of cancer cells into surrounding tissue and the vasculature is an initial step in tumor metastasis. This requires chemotactic migration of cancer cells, steered by protrusive activity of the cell membrane and its attachment to the extracellular matrix.

On the reversibility of tumor cells
Medical Hypotheses, 1981A review is given of several cases in which a neoplastic cell becomes a normal one. Emphasis is placed on the Lucké adenocarcinoma in the frog and on the case of terminal differentiation. The mysteries of cell fusion studies are discussed as well as the experiments of Mintz et al on teratocarcinoma of the mouse. In the case of the Lucké adenocarcinoma,

Local tissue invasion and the formation of metastatic lesions are characteristic properties of many malignant tumors. The formation of metastases is a complex process involving the passage of tumor cells from the site of the primary bulk tumor through successive connective tissue barriers, ultimately resulting in the growth of secondary tumor cell ...

The cytoskeleton in tumor cells
Pathology - Research and Practice, 1982During the past few years several laboratories investigated the occurrence of cytoskeletal components in epithelial and mesenchymal cells by electron microscopy and/or immunocytochemical methods in a number of tumor types growing in vitro or in the body.

The development of modern surgical staging and effective chemotherapy regimens has markedly improved outcome of treatment of ovarian germ cell tumors. Almost all patients with completely resected tumors will survive their disease. Those with tumors other than dysgerminoma should all receive adjuvant chemotherapy. Patients with stage IA dysgerminoma can

Testicular cancer is rare, accounting for 1% to 2% of all male malignancies. Nearly 90% to 95% of tumors arising in testis are germ cell in origin. Other sites of malignant germ cell tumors include the retroperitoneum, mediastinum, sacrococcygeal region, and pineal gland. The highest incidence is seen in Scandinavian countries, particularly Denmark (1).

Circulating tumor cells (CTCs) can be separated and characterized from normal hematopoietic cellular constituents by a variety of methods. Different strategies have included separation by physical characteristics, such as size or weight, or by biological characteristics, such as expression of epithelial or cancer-specific markers.
