Relapsed and refractory yolk sac tumor of the peritoneum (mesentery): A case report and literature review
ConclusionPostoperative histopathology and immunohistochemistry are gold standards for the diagnosis of peritoneal YST. The standard first-line treatment is surgery plus BEP chemotherapy. Second-line therapy regimens and above, including VIP and TIP, improve the prognosis of recurrent germ cell tumors. This relapsed and refractory patient with peritoneal YST benefits from the secondary BEP´ chemotherapy. (Source: Frontiers in Oncology)

Yolk sac tumours of the orbit and sinonasal tract
CONCLUSION: Sino-orbital yolk sac tumours are rare and have variable presentations, dependent on the extent of local invasion. Early diagnosis and treatment with multimodal therapy are paramount in having improved overall survival.PMID:35938374 | DOI:10.1080/01676830.2022.2106375 (Source: Orbit)

Schinus terebinthifolia Raddi leaf lectin is an antiangiogenic agent for Coturnix japonica embryos
An Acad Bras Cienc. 2022 Aug 1;94(3):e20211297. doi: 10.1590/0001-3765202220211297. eCollection 2022.ABSTRACTAngiogenesis (budding of new blood vessels) is involved in several processes, including the development of embryos and growth of tumors. Schinus terebinthifolia leaves express an antitumor lectin (SteLL). This work hypothesized that SteLL can interfere with the formation of a vascular network from preexisting vessels. To test this hypothesis, the effect of SteLL on the angiogenesis process was assessed using an in vivo model of yolk sac membrane of Coturnix japonica embryos. SteLL was isolated with purification fact...

Cancers, Vol. 14, Pages 3646: Diagnosis and Treatment of Pineal Region Tumors in Adults: A EURACAN Overview
Weller Ahmed Idbaih Pineal region tumors are rare intracranial tumors, accounting for less than 1% of all adult intracranial tumor lesions. These lesions represent a histologically heterogeneous group of tumors. Among these tumors, pineal parenchymal tumors and germ cell tumors (GCT) represent the most frequent types of lesions. According to the new WHO 2021 classification, pineal parenchymal tumors include five distinct histotypes: pineocytoma (PC), pineal parenchymal tumors of intermediate differentiation (PPTID), papillary tumor of the pineal region (PTPR), pinealoblastoma (PB), and desmoplastic myxoid tumor of th...

Villin expression in human tumours: a tissue microarray study on 14,398 tumours
CONCLUSION: Our data support a high utility of villin immunohistochemistry for the identification of tumors with gastrointestinal, pancreatobiliary, and yolk sac tumor origin. However, considering that at least a weak villin positivity in some tumor cells occurred in 54 different tumor categories, villin immunohistochemistry should be applied as a part of a marker panel rather than as a stand-alone marker.PMID:35866621 | DOI:10.1080/14737159.2022.2104122 (Source: Expert Review of Molecular Diagnostics)
