“…Several cases of tumor-to-tumor metastases and collision tumors have been reported previously (4)(5)(6)(7)(8)(9). Based on case series and retrospective studies, the most frequent donor tumor appears to be lung carcinoma and the most common malignant recipient is renal cell carcinoma (10,11).…”

Intracranial metastasis from breast cancer is a relatively common finding, however, the appearance of breast cancer metastasis in a meningioma is very rare. Several cases of tumor-to-tumor metastasis and collision tumors have been reported previously, with meningioma being implicated as the most common benign intracranial neoplasm to harbour the metastasis. Occasionally, the discovery of a tumor-to-meningioma metastasis may herald the diagnosis of an occult primary malignancy. Careful histopathological assessment of the resected meningioma specimen is pivotal to the management of these patients, as this will alter the treatment plan and prognosis considerably. Intracranial meningioma with collision breast cancer as primary presentation of an undiagnosed metastatic breast cancer is extremely rare. The current study presents a case of intracranial meningioma with collision breast cancer as a primary presentation, and reviews the available evidence for this unusual disease entity.

Collision tumor of bone: primary chondrosarcoma of bone as a rare recipient of tumor-to-tumor metastasis from metastatic breast carcinoma

Abstract: Collision tumors are the rare phenomenon of two histologically distinct tumors occurring in the same anatomic location. We report an unusual case of metastatic breast carcinoma colliding with primary grade 1 chondrosarcoma in the femur of a 58-year-old female.
