Only a minority of ependymomas present in the spinal cord. We report on a child with recurrence of a rare anaplastic clear cell type of ependymoma. This was initially misdiagnosed as a World Health Organization grade I myxopapillary ependymoma because this type of ependymoma occurs more commonly and the magnetic resonance imaging features and location at the conus medullaris were considered characteristic.

Background: Hepatocellular carcinoma (HCC) encompasses rare variants like chromophobe hepatocellular carcinoma (CHCC) characterized by distinct histological features and molecular profiles.
Case Report: A 56-year-old male with chronic hepatitis C, presenting pain in the right hypochondrium. Imaging revealed a solitary liver lesion, subsequently resected and histologically diagnosed as HCC.

Background: Given advancements in adjuvant treatments for non-small-cell lung cancer (NSCLC) with epidermal growth factor receptor (EGFR) and anaplastic lymphoma kinase (ALK)-targeted therapies, it is important to consider postoperative targeted therapies for other early-stage oncogene-addicted NSCLC. Exploring baseline outcomes for early-stage NSCLC with these rare mutations is crucial.
Objectives: This study aims to assess relapse-free survival (RFS) and overall survival (OS) in patients with resected early-stage NSCLC with rare targetable driver mutations.

Soft tissue tumors with EWSR1/FUS fusion to genes encoding the cyclic adenosine monophosphate response element-binding (CREB) transcription factor family (ATF1, CREB1, and CREM) are rare and heterogeneous aggressive tumors, often found in the peritoneal cavity. Here, we report two cases of malignant epithelioid tumors with EWSR1::CREB fusion involving the kidney in females in their 30 s. Both tumors appeared as solitary masses, measuring 5.

Anaplastic thyroid carcinoma (ATC) ranks among the most lethal human cancers. Increased migratory and invasive capabilities are critical in malignancy and are often secondary to epithelial-mesenchymal transition (EMT). However, it is not clear whether the invasive behavior of ATC is associated with the presence of EMT.
