Background: Ameloblastoma is a rare benign odontogenic tumor with a metastasis rate estimated at 2% of cases, mainly involving the lung (80%) and lymph nodes (20%).
Methods: We hereby present the case of a 26 year old patient with a history of locally recurrent mandibular ameloblastoma who developed a temporal intracranial ameloblastoma tumor requiring a collaborative neurosurgical and maxillo-facial radical surgical approach.
Conclusion: Although ameloblastomas are histologically benign, the temporal topography questions the dissemination pathophysiology of the tumor (metastasis or local extension through temporal muscle fibers), mainly relevant in cases of multiple recurrences.

Background: Immune checkpoint inhibition therapies have provided remarkable results in numerous metastatic cancers, including mismatch repair-deficient (dMMR) colorectal cancer (CRC). To evaluate the potential for PD-1 blockade therapy in a large population-based cohort, we analyzed the tumor microenvironment and reviewed the clinical data and actualized treatment of all dMMR CRCs in Central Finland province between 2000 and 2015.
Material And Methods: Of 1343 CRC patients, 171 dMMR tumors were identified through immunohistochemical screening.

Osteosarcoma (OS) is the most common primary malignant bone tumor in childhood. Patients who present with metastatic disease at diagnosis or relapse have a very poor prognosis, and this has not changed over the past four decades. The Wnt signaling pathway plays a role in regulating osteogenesis and is implicated in OS pathogenesis.

The field of cardio-oncology has traditionally focused on the impact of cancer and its therapies on cardiovascular health. Mounting clinical and preclinical evidence, however, indicates that the reverse may also be true: cardiovascular disease can itself influence tumor growth and metastasis. Numerous epidemiological studies have reported that individuals with prevalent cardiovascular disease have an increased incidence of cancer.

Background: The histologic classification of rhabdomyosarcoma (RMS) as alveolar (aRMS) or embryonal (eRMS) is of prognostic importance, with the aRMS being associated with a worse outcome. Specific gene fusions (PAX3/7::FOXO1) found in the majority of aRMS have been recognized as markers associated with poor prognosis and are included in current risk stratification instead of histologic subtypes in localized disease. In metastatic disease, the independent prognostic significance of fusion status has not been definitively established.

A 64-year-old woman underwent initial 18F-FDG PET/CT staging for a suspicious endometrial mass, which showed high uptake in the endometrial mass and a focal uptake in a known left thyroid nodule. Histology revealed a high-grade large cell neuroendocrine carcinoma of the endometrium with FIGO (International Federation of Gynecology and Obstetrics) stage Ib. Further explorations revealed a synchronous thyroid metastasis.
