An adult male Hooded Crane was found dead on the Izumi plane. At autopsy, subcutaneous nodules were found around the medial and lateral sides of the left distal tibiotarsus bone. The largest cross-section of the masses revealed a multilobular pattern, with small amounts of viscous mucus. Histopathologically, the nodules were composed of three types of neoplastic cells: chondrocytic cells with abundant lightly basophilic cartilaginous matrices, mesenchymal cells and a small portion of the neoplastic tissue consisted of undifferentiated neoplastic cells exhibiting a high mitotic count and frequent multinucleation. This is the first case of a chondrosarcoma including undifferentiated neoplastic cell proliferation in a wild Hooded Crane.

Stem cells are undifferentiated or partially differentiated cells with an extraordinary ability to self-renew and differentiate into various cell types during growth and development. The epithelial-mesenchymal transition (EMT), a critical developmental process, enhances stem cell-like properties in cells, and is associated with both normal stem cell function and the formation of cancer stem cells. Cell stemness and the EMT often coexist and are interconnected in various contexts.

Introduction: A positive surgical margin (R1 resection) is a relevant risk factor for local recurrence in patients with pancreatic ductal adenocarcinoma of the pancreas (PDAC). An intraoperative liquid biopsy (ILB) based on tumor cell mobilization could help to detect R1 resection intraoperatively.
Objective: To evaluate the potential role of the intraoperative circulating tumor cells (CTCs) and cluster mobilization on the R0/R1 detection.

Thyroid cancer has become the most common endocrine malignancy. Although the majority of differentiated thyroid cancers have a favorable prognosis, advanced thyroid cancers, iodine-refractory thyroid cancers, and highly malignant undifferentiated carcinomas still face a serious challenge of poor prognosis and even death. Cancer stem cells are recognized as one of the central drivers of tumor evolution, recurrence and treatment resistance.

Article Synopsis
- Sarcomas are not typically associated with Lynch Syndrome (LS), but recent literature suggests a connection, prompting a national study to investigate their characteristics in LS patients.
- The SarcLynch study included 81 patients, finding that 83% had soft-tissue sarcomas, particularly pleomorphic variants like undifferentiated pleomorphic sarcoma and pleomorphic rhabdomyosarcoma, with 40% having sarcoma as their first cancer event.
- Results showed a high prevalence of mismatch repair deficiency and promising responses to immune checkpoint inhibitors, suggesting the need for screening and potential immunotherapy for these sarcomas.

Based on the antigenic similarity between tumor cells and embryonic stem cells (ESCs), several recent studies report the use of intact murine ESCs or exosomes from murine ESCs as cancer vaccines. Since the capacity for self-renewal is one of the most specialized properties shared between ESCs and a subset of tumor cells, cancer stem cells (CSCs), we investigated whether the undifferentiated state of murine ESCs is essential for the prophylactic effectiveness of an ESC-based vaccine. The undifferentiated state of ES-D3, a murine ESC line, was essential for their anchorage-independent growth potential.
