Cellular schwannoma is a rare variant of schwannoma, showing high cellularity and a low mitotic index. A 64-year-old man was admitted to our hospital with a 2-month history of productive cough. Chest computed tomography showed an endobronchial tumor with complete atelectasis of the right lower lobe. Bronchoscopy showed an endobronchial tumor occluding the intermediate bronchus that was diagnosed as a cellular schwannoma on biopsy and was successfully excised with a right lower sleeve lobectomy to preserve the middle lobe. The postoperative course was uneventful, and the patient remains well with no sign of recurrence at the 7-year follow-up.

Background: Brain intraparenchymal schwannoma is a rare clinical entity, generally curable with adequate resection.
Methods And Results: We describe a case in a male patient first presenting at 19 months of age, the youngest reported age for this lesion. It also appears to be the first case connected to a germline TSC2 p.

Cellular schwannoma is a schwannoma subtype with histopathologic features resembling those of malignant tumors. We report a case of a cellular schwannoma arising at the resection margin of an anterior mediastinal leiomyosarcoma. An 88-year-old woman who had undergone resection of an anterior mediastinal leiomyosarcoma 2 years previously developed a mediastinal tumor at the resection margin, raising suspicion of leiomyosarcoma recurrence.

: Transcriptome profiling can reveal prognostic biomarkers and therapeutic vulnerabilities for directing clinical care. Currently, there are no biomarkers that can accurately predict patient prognosis regarding tumor growth and the tumor immune microenvironment in vestibular schwannomas. This study aimed to investigate the mechanisms of tumor growth using bulk RNA-seq and single-cell data from patients with vestibular schwannomas.

Introduction: Schwannoma is a type of slow growing benign nerve sheath tumor arising from Schwann cells. Peripherally, they are found in association with the ulnar, sciatic and posterior tibial nerves. Peripheral schwannomas, neurofibromas and malignant PNSTs are collectively grouped as peripheral nerve sheath tumors.

Schwannomas are tumors that originate from the glial cells of the nervous system and can occur on myelinated nerve fibers throughout the body, especially in the craniofacial region. However, pancreatic schwannomas are extremely rare. We report a case of a pancreatic schwannoma that was difficult to differentiate from other pancreatic tumors preoperatively.
