“…A total of 37 studies dealing with other topics, such as neuroimaging, pathology or other anatomic localizations, were excluded; the last screening examined the full texts. Finally, we included eight articles in our review ( Table 2 ) [ 91 , 92 , 93 , 94 , 95 , 96 , 97 , 98 ].…”

“…Rais G. et al reported that FDG-PET/CT can provide reliable diagnostic information about TTM and serve to guide a biopsy procedure for a specific metastatic lesion, even if most cases were discovered incidentally in living patients or during autopsy. Furthermore, the authors reported the first case of an incidental PET/CT finding consistent with a TTM from lung cancer to RCC [ 93 ].…”

“…In addition to adenocarcinoma, other lung cancer histologies were associated with TTM. Two cases of squamous cell lung carcinoma were reported previously in the literature [ 93 , 95 ]. Furthermore, we found two cases of neuroendocrine lung carcinoma metastasis in a ccRCC [ 91 , 96 ].…”

Tumor-to-tumor metastasis (TTM) is a rare phenomenon documented in patients with multiple primary cancers. This condition is defined as a metastasis between two true primary tumors. The most frequently reported recipient tumor is renal cell carcinoma (RCC), and the lung carcinomas are the most common metastatic tumor donors. Therefore, this paper attempts to address the current gap in knowledge about this rare phenomenon. The first part of this review outlines the recently proposed models and mechanisms involved in the TTM process. The second part then summarizes and analyzes previous case reports in the literature. We also present our experience with the case of lung cancer that metastasized into RCC. Given the sporadic incidence of TTM, no specific management guidelines exist. Therefore, considering TTM in patients with multiple primary tumors is important as it could potentially modify the oncological management offered.

“…To date, more than 100 TTM cases were published in the literature and lung cancers are the most common donors in TTM, followed by carcinomas of the breast, gastrointestinal tract, prostate, and thyroid. The most frequent recipient tumor is renal cell carcinoma, followed by meningioma and thyroid tumor [2][3][4][5]. Thymoma is considered a rare neoplasm with an overall incidence of 1.5 cases per million whereas the incidence of thymic malignancies is 0.13 cases/100.000 persons/year [6].…”

Tumor-to-tumor metastasis is defined as when metastasis from a primary tumor (donor) grows in a different primary neoplasm (recipient). Due to the structure of the thymus and the low incidence rate, thymic epithelial neoplasm has been rarely described in the literature as a recipient for metastases. In this report, a patient with advanced prostatic cancer and under control after chemo/hormone therapy was directed to our thoracic surgery unit for an anterior mediastinal mass detected during the staging workup for prostate disease. A limited uptake at fluorodeoxyglucose-positron emission tomography (FDG-PET) in the mediastinal lesion, while the surrounding tissue showed diffusely negative hypermetabolism, suggested a second primary thymic epithelial tumor with a possible carcinomatous differentiation. A thymectomy through a median sternotomy was carried out. Histopathological analysis after thymectomy revealed a type A thymoma with multiple elements of prostate adenocarcinoma within it. The foci of prostate adenocarcinoma were co-located in the context of the thymoma, revealing what is defined as a tumor-totumor metastasis. To our knowledge, this is the first report describing a thymoma as the recipient of metastases coming from a primary extrathoracic tumor without the involvement of other thoracic organs.
