Tumor-to-tumor metastasis is a well recognized phenomenon. Although any tumor may be potential recipient of metastasis, renal cell carcinoma and meningioma are the most common malignant and benign recipients, respectively, whereas the lung and breast are the most common metastatic donors respectively, in both settings. Patients with hereditary cancer syndromes may be at higher risk for the development of tumor-to-tumor metastases. The most common pattern of tumor-to-tumor metastasis for… 
Tumor-to-tumor metastasis: a rare case of breast carcinoma metastasizing to a pheochromocytoma, and a literature review
TLDR
This is the second published case of pheochromocytoma with tumor-to-tumor metastasis from an invasive ductal carcinoma of the breast and it is highlighted the importance of awareness of tumor- to-t tumour metastasis in pathological diagnosis.
Tumor-to-Tumor Metastasis: Prostate Carcinoma Metastatic to Soft Tissue Sarcoma, a Previously Unreported Event
TLDR
The first documented case of tumor-to-tumor metastasis involving prostatic adenocarcinoma and myxoid liposarcoma is reported, the available literature for carcinoma metastatic to sarcoma are reviewed, and the current situation is discussed within the context of the established criteria for the classification of combination tumors.
Malignant Melanoma Metastatic to Oligodendroglioma: Case Report and Literature Review of Tumor-to-Tumor Metastasis to Gliomas.
TLDR
This is the first reported case of malignant melanoma metastasizing to an oligodendroglioma that has been confirmed by immunohistochemistry and genetic analysis.
Papillary thyroid carcinoma metastasizing to anaplastic meningioma: an unusual case of tumor-to-tumor metastasis
TLDR
This is the first example in the literature of a donor tumor metastasizing to a high-grade recipient tumor, involving papillary thyroid carcinoma (PTC) believed to have metastasized to an anaplastic meningioma (WHO grade 3).
Brain metastasis: clinical characteristics, pathological findings and molecular subtyping for therapeutic implications
TLDR
This work discusses here the epidemiology, general gross and microscopic features of brain metastases with emphasis on how to differentiate them from primary brain tumors using immunohistochemistry, and unique pathologic patterns ofbrain metastases (namely, dural metastasis, leptomeningeal carcinomatosis, miliary metastasis), with their clinical and radiological characteristics.
Breast carcinoma metastasis in a resected meningioma with early diagnosis of oligometastatic disease: a case report.
TLDR
A 56-year-old woman with a history of bilateral, localized, invasive lobular breast carcinoma treated with surgery, systemic therapy, and adjuvant radiation presented five and two years post-treatment with progressive neurological symptoms.
Simultaneous meningioma and brain metastasis from renal cell carcinoma - a rare presentation. Case report.
TLDR
This study provides the first description of an association between these two tumors, and rare presentations such as simultaneity with meningioma should alert neurosurgeons to provide the best oncological treatment.
Metastasis of pulmonary adenocarcinoma to right occipital parafalcine meningioma
TLDR
A case of metastasis of lung adenocarcinoma into intracranial meningioma into cancer metastasis is presented, with a 70-year-old woman who died suddenly 7 days after surgery.
Metastasis of a Dorsal Melanoma to a Pituitary Adenoma Mimicking Pituitary Apoplexy
TLDR
The similarity in the clinical presentation of the two entities—pituitary apoplexy and metastasis of the melanoma into a pituitary adenoma—and the rarity of this type of metastization alert to challenges in the differential diagnosis that may confound the neurosurgeon's decision.

Tumor-to-tumor metastasis: pathology and neuroimaging considerations.
TLDR
The limitations of standard radiological imaging techniques, which cannot reliably identify the presence of metastasis within a meningioma are compared with physiology-based neuroimaging methods, such as perfusion MR and MR spectroscopy, which may be more useful in noninvasively differentiating tumor histology.
Melanoma Metastatic to Central Neurocytoma: A Novel Case of Tumor-to-tumor Metastasis
TLDR
The most common pattern of tumor-to-tumor metastasis for intracranial neoplasms, in which an aggressive high-grade malignancy serves as the source tumor and a more indolent neoplasm serving as the recipient tumor, is affirmed by the present novel example.
Tumor to tumor metastasis.
To the Editor.— Metastasis from one neoplasm to an unrelated coexisting neoplasm is a very rare autopsy finding; to our knowledge, fewer than 100 cases have been reported in the English literature.
Tumor-to-tumor metastasis: esophageal carcinoma metastatic to an intracranial paraganglioma.
TLDR
A unique case of esophageal carcinoma metastatic to an intracranial paraganglioma found using MR imaging in an 81-year-old man who presented with a 3-week history of progressive headache and blurred vision is reported.
Metastasis of breast carcinoma to intracranial meningioma.
TLDR
Patients with a history of breast cancer and a solitary, intracranial mass with radiological features consistent of meningioma should be evaluated surgically for a metastatic lesion.
Metastases of cancer to primary intracranial tumor.
TLDR
Three cases of metastatic carcinoma in meningioma are found; in two the metastasis originated from a primary site in the breast, and in one, from the bronchus.

TLDR
The patient, who presented for evaluation of bifrontal headache, was found on computerized tomography to have a partially calcified right frontal mass, and work-up disclosed an infiltrative ductal adenocarcinoma of the breast.
