Epithelioid pleural mesothelioma successfully treated with perioperative immunotherapy: a case report.

Background: Pleural mesothelioma, characterized by a dismal prognosis even with multimodal therapy, has seen emerging interest in immune checkpoint inhibitors (ICIs) due to their demonstrated efficacy. Here, we present a case of epithelioid-type pleural mesothelioma with chest wall invasion treated with definitive ICI therapy, resulting in a remarkable pretreatment effect.

Case Presentation: A 46-year-old man was diagnosed with an abnormal chest shadow on a medical check, and a computed tomography scan showed pleural thickening at the dorsal right upper chest wall.

Identification of micro-recurrent lesions using methylene blue for mediastinal ectopic parathyroid adenoma: a case report.

Background: Mediastinal ectopic parathyroid adenomas are rare, and several methods are used to diagnose and localize them preoperatively. Technetium-99m methoxy isobutyl isonitrile scintigraphy has been used to diagnose parathyroid tumors. However, it is difficult to identify tumors buried in adipose tissue during surgery.
