Article Abstract
Introduction: Malignant teratomas can be either immature teratomas or they can develop after treatment of other malignant germ cell tumors with chemotherapy or radiotherapy. Spontaneous malignant transformation of mature teratomas is very rare.
Observation: We report the case of a patient complaining of atypical chest pain. Chest plain radiography showed a right anterior mediastinal mass. Computed tomography revealed a heterogeneous mediastinal mass with fat areas and calcification. There were hilar and mediastinal lymph nodes as well as lung parenchymal nodules. CT-guided and then surgical biopsies confirmed the diagnosis of a mature teratoma, which had degenerated into a digestive adenocarcinoma.
Conclusion: Spontaneous malignant transformation of mature mediastinal teratoma is very rare. The diagnosis of malignant transformation is based on radiological examinations, laboratory tests and histological studies.
Introduction: Hepatic artery pseudoaneurysm (HAP) is a rare and potentially life-threatening condition associated with high mortality. This study aims to review the etiology, clinical manifestations, management, and outcomes of patients diagnosed and treated for HAP at the Mayo Clinic.
Methodology: This study was a retrospective chart review of medical records for patients diagnosed and treated for hepatic artery pseudoaneurysm (HAP) at the Mayo Clinic (Florida, Minnesota, and Arizona) between September 1, 1998, and June 30, 2022.
MicroRNAs (miRNAs) are small non-coding RNA molecules that are present in all cell types and bodily fluids and are commonly dysregulated in cancer. miRNAs in cancer have been studied by measuring levels in cell lines, tumour tissues, and in circulation; however, no study has specifically investigated miRNA expression in patient-matched samples across all three sample types. Canine osteosarcoma is a well-established spontaneously occurring model of human osteosarcoma for which matched samples are available.
Background: The submental artery island flap (SIF) is a valid option for palatal reconstruction. However, the main limitation for its application for palatal defects is the arc of rotation. A novel modification for tunneling of the antegrade design of SIF that allows a compliant easy reach to the defect is described.
The management of persistent malignant pleural effusion (MPE) or uremic pleural effusions requires the removal of pleural fluid and the prevention of recurrence through pleurodesis. Pleurodesis involves injecting a sclerosing agent into the pleura to encourage adhesion between the two layers, ultimately obliterating the pleural space. Povidone-iodine is a potential pleurodesing agent.
Objective: The aim of this study was to evaluate the serum hCG level in the differential diagnosis between non-molar miscarriage and complete hydatidiform mole in<11 weeks gestation.
Methods: This was a retrospective collaborative cohort study. This study included women with gestational age<11 weeks, with ultrasound evidence of failed pregnancy and available serum hCG pre-uterine evacuation, divided into two groups: the non-molar miscarriage group and the complete hydatidiform mole group.
