Surgical resection and lymphadenectomy are the mainstay of curative treatment for oesophagogastric cancer. In this study we evaluate the results of intravascular methylene blue injection into oesophagectomy and gastrectomy specimens as a tool to increase lymph node detection. A prospective and descriptive study was run on 24 patients (11 oesophagus, 13 stomach cases).

Article Synopsis
- Intracardiac masses, like myxomas, can sometimes be identified following a stroke, but distinguishing them through echocardiography can be challenging.
- A case study involved a 58-year-old man with various health issues who suffered an ischemic stroke; his echocardiogram showed a large mass in the left atrium, leading to a diagnosis of myxoma after surgery.
- Myxomas may not show symptoms for a long time and can be linked to embolic complications, emphasizing the need for a comprehensive, team-based management approach.

Background: Non-meningothelial intracranial mesenchymal tumors are a heterogeneous group of central nervous system neoplasms endowed with great variability clinically and histologically. For this precise reason, significant difficulties exist in specifically cataloguing tumor entities with such distant characteristics and such uncertain clinical course.
Case Description: In an attempt to increase the knowledge inherent in this type of central nervous system lesions we report a case of a rare and unusual myxoid mesenchymal tumor of difficult anatomopathological classification characterized by rapid progression and optimal therapeutic response after combined surgical and radiotherapy treatment, with histo-molecular definition and DNA methylation profile.

Perivascular epithelioid cell neoplasms (PEComas) and epithelioid angiomyolipomas (EAMLs) are two different denominations for the same "mesenchymal tumor composed of histologically and immunohistochemically distinctive perivascular epithelioid cells". Hepatic PEComa/EAML is a very rare neoplasm, and only 29 case reports of hepatic PEComa and 25 of hepatic EAML have been reported in the current literature. A clear female predominance with a mean age at diagnosis of 42.
