The clinical features, diagnostic work-up and difficulties in establishing a diagnosis on endoscopic biopsy specimens were retrospectively analysed in five patients with ampullary tumors. In addition, the technique of local papillary resection is reported. Indications for local resection are: elderly patients with severe co-existing diseases, patients with benign ampullary tumors which are either adenomatous or show epithelial dysplasia or patients with inconclusive preoperative endoscopic biopsy or peroperative frozen sections.

Background: Optic nerve schwannomas are an extremely rare pathology in neurosurgery. Their origin is rather debatable given the structure of the optic nerve, which does not typically have Schwann cells therein. However, a number of clinical cases of optic nerve tumors classified as schwannomas have been described in the literature.
View Article and Find Full Text PDFAtypical lipomatous tumors/well-differentiated liposarcomas (ALT/WDLPS) are low-grade, slow-growing, and locally aggressive tumors. We investigated clinical outcomes and recurrence factors for ALT/WDLPS of the extremities. This is retrospective study across three institutions which included patients who underwent surgery for ALT/WDLPS from 2001 to 2019.

The somato-cognitive action network (SCAN) consists of three nodes interspersed within Penfield's motor effector regions. The configuration of the somato-cognitive action network nodes resembles the one of the 'plis de passage' of the central sulcus: small gyri bridging the precentral and postcentral gyri. Thus, we hypothesize that these may provide a structural substrate of the somato-cognitive action network.

The widespread adoption of high-resolution computed tomography (CT) screening has led to increased detection of small pulmonary nodules, necessitating accurate localization techniques for surgical resection. This review examines the evolution, efficacy, and safety of various localization methods for small pulmonary nodules. Studies focusing on localization techniques for pulmonary nodules ≤30 mm in diameter were included, with emphasis on technical success rates and complication profiles.

Basal cell carcinomas are common facial malignancies with minimally invasive treatment approaches effective in the majority of cases. Recurrent aggressive lesions pose significant challenges and need wide local excision with major reconstruction. Geriatric patient with multiple comorbidities needs customized reconstructions to minimize morbidity.
