Metastasis of Tumor to Second Different Tumor: Collision Tumors
JAMA: The Journal of the American Medical Association, 1970To the Editor:— The phenomenon of tumor-to-tumor metastasis, albeit infrequent, has been reported by a number of observers. Osterberg 1 reviewed three previously reported cases, and added two: one of bronchial origin, the other probably of renal origin, both spreading to meningiomas.

Tumors and Tumor-Like Lesions [PDF]
, 2003 Peripheral nerve tumors are uncommon, nerve sheath tumors, schwannoma and neurofibromas being the most frequent. Their clinical signs and symptoms are often unspecific, which is why they may pose a diagnostic problem; this is particularly true for the neck, where a palpable mass is often mistaken for an enlarged lymph node by the referring clinician ...

Tumor-to-Tumor Metastasis: Extracranial Tumor Metastatic to Intracranial Tumors
2011Tumor-to-tumor metastasis (TTM) is a relatively rare but well-documented phenomenon. When malignant tumor metastasizes to an intracranial tumor, meningiomas are most often the recipient; and breast or lung carcinoma the most common donor (primary tumor). The diagnosis of TTM can be made only by histopathological examination.

Tumors of the axis (C2 vertebra) are rare. The location and unique structure of the upper cervical spine and proximity to vital structures make diagnosis and treatment difficult. Appropriate clinical and radiographic evaluation, biopsy, oncologic and surgical staging, and adequate operative techniques and adjuvant treatments should be considered.

Tumors and Tumorous Conditions of Bone [PDF]
, 1994 Clinically, tumors and tumorous conditions of bone are among the most frequently studied and diagnostically challenging diseases, the primary means of whose diagnosis is radiography. The absolute neccessity of radiography is well established so that any single diagnostic scheme that does not incorporate it is deemed inappropriate.

Current Opinion in Oncology, 1990
Of the many types of tumors located in the mediastinal compartments, most are metastatic. The most common adult tumor in the anterior compartment is thymoma. A number of important cytogenetic, immunohistochemical, and molecular analytical observations have been reported over the past year regarding this tumor.

Abrikossoff's tumor is a disease that more commonly affects the oral cavity but can also occur at other sites. It develops between the second and sixth decades of life, more frequently among women and blacks. The neoplasm can affect all parts of the body.

Tumors of the neck are important to discuss because they are not uncommon. Because of the fact that malignancy is not rare in them it is important to determine their character as early as possible; the need to know their origin and character is not far removed from that of tumors of the breast.

Focal midbrain tumors in childhood are usually low-grade astrocytomas amenable to surgical resection. Small lesions presenting only with hydrocephalus are best treated by cerebrospinal fluid diversion without biopsy or surgical resection.

The hypothesis that tumors are angiogenesis dependent has, in the past decade, generated new investigations designed to elucidate the mechanism of angiogenesis itself. Many laboratories are now engaged in this pursuit. Some are studying angiogenesis that occurs in physiological situations, whereas others are interested in angiogenesis that dominates ...
