Typical transcranial approaches are insufficient for adequate visualization and resection of skull base tumors. Different approaches with multiple modifications have been attempted. Here, we describe a new approach for a lesion that is central and hard to treat by conventional craniotomy and successful reconstruction with calvarial bone graft and titanium mesh plate. A 69-year-old female patient presented with recurrent meningioma. The tumor had invaded the frontal lobe, right supraorbital rim, and ethmoidal bone. We performed a modified anterior craniofacial approach that fully exposed the tumor and invaded bone. In consideration of the patient's age and cosmetic result, the tumor and invaded bone was resected and the defect area was reconstructed with titanium mesh and calvarial bone graft. At 6 months postoperative the patient had no complications and was satisfied with the esthetic result. We report this case to demonstrate the successful approach and reconstruction using this technique.

Background: Intracranial solitary fibrous tumors (SFTs) are rare mesenchymal tumors often presenting with dural-based lesions. These tumors can exhibit aggressive characteristics with high recurrence rates and extracranial metastasis. While SFTs occasionally invade venous sinuses, cases where the tumor arises within the venous sinus are rare.

Background: Hepatocellular carcinoma (HCC) frequently invades the portal vein, leading to early recurrence and a poor prognosis. However, the mechanisms underlying this invasion remain unclear. In this study, we aimed to detect portal vein circulating tumor cells (CTCs) using a Glypican-3-positive detection method and evaluate their prognostic significance.

Muscle-invasive bladder cancer (MIBC) with cardiac metastasis typically carries a very poor prognosis. A Black woman in her 70s developed high-grade urothelial carcinoma with squamous differentiation invading the bladder muscle. Despite chemotherapy, radiation, and nephrostomy, the disease progressed.

When cells in a primary tumor work together to invade into nearby tissue, this can lead to cell dissociations-cancer cells breaking off from the invading front-leading to metastasis. What controls the dissociation of cells and whether they break off singly or in small groups? Can this be determined by cell-cell adhesion or chemotactic cues given to cells? We develop a physical model for this question, based on experiments that mimic aspects of cancer cell invasion using microfluidic devices with microchannels of different widths. Experimentally, most dissociation events ("ruptures") involve single cells breaking off, but we observe some ruptures of large groups (~20 cells) in wider channels.

Compared to sun-exposed melanomas, acral melanomas are genetically diverse and occur in areas with low sun exposure and high mechanical loads. During metastatic growth, melanomas invade from the epidermis to the dermis layers through dense tumor stroma and are exposed to fibrillar collagen architectures and mechanical stresses. However, the role of these signals during acral melanoma pathogenesis is not well understood.
