Giant ganglioneuroma of the mediastinum: a case report.
Front Oncol
October 2024
Department of Radiology, The Third Affiliated Hospital of Zunyi Medical University (The First People's Hospital of Zunyi), Zunyi, China.
Ganglioneuroma (GN) is a rare benign neurogenic tumor that originates from the sympathetic nerves. It is extremely uncommon to find a lesion originating from the mediastinum that occupies the entire left hemithorax. In this report, we present the case of a 48-year-old female patient with a large mediastinal GN who presented with cough, sputum, and wheezing.

BACKGROUND Non-neurogenic neurogenic bladder involves fluctuating flow rates due to involuntary muscle contractions during voiding in those with normal neurological function. The diagnostic challenge lies in distinguishing between massive urinary bladder distension and ovarian tumors. While various pathologies mimicking ovarian tumors are documented, cases of a massively distended urinary bladder, known as giant urinary bladder, posing as such are notably scarce.

Department of Neurology, National Taiwan University Hospital, No. 7 Chung-Shan South Road, Taipei, 10002, Taiwan.
Background: To investigate the peripheral nervous system involvement in sialidosis with typical features of myoclonus, seizure, and giant waves in somatosensory evoked potentials suggesting hyperexcitability in the central nervous system.
Methods: The clinical presentation of patients with genetically confirmed sialidosis was recorded. Neurophysiological studies, including nerve conduction studies (NCSs), F-wave studies, and needle electromyography (EMG), were performed on these patients.
Cytopathology of Chondromyxoid Fibroma: Report of 2 Cases with Immunocytochemical Expression of GRM1.
Acta Cytol
April 2024
Department of Pathology, Teikyo University School of Medicine, Tokyo, Japan.
Article Synopsis
- Chondromyxoid fibroma (CMF) is a rare benign bone tumor mainly found in young males, with GRM1 overexpression serving as a potential diagnostic marker.
- Two case studies—a 15-year-old girl with a rib tumor and a 14-year-old boy with a toe tumor—highlight similar cytological features such as spindle-shaped cells and metachromatic matrices, making differentiation from similar tumors challenging.
- GRM1 immunocytochemical staining proves helpful in supporting CMF diagnosis and shows promise for use alongside Papanicolaou-stained specimens in the diagnostic process.
Multimodality imaging of an unusual giant cell tumor of thoracic spine with mediastinal invasion: a case report.

Department of Nuclear Medicine, Peking University First Hospital Beijing 100034, China.
Giant cell tumor (GCT) is a benign yet locally aggressive bone neoplasm typically situated in the juxta-articular metaphysis of long bones. Although spinal involvement is rare, it is predominantly reported in the axial skeleton, with the sacrum being the primary location. Conversely, GCTs are notably uncommon in the thoracic spine.
