Tumors are classified in a number of ways, one of the simplest being according to their origin and whether they are malignant or benign. Tumors of mesenchymal origin include fibroelastic tumors and those of bone, fat, blood vessels, and lymphoid tissue; they may be benign or malignant (...
Organoids are a new type of 3D model for tumor research, which makes up for the shortcomings of cell lines and xenograft models, and promotes the development of personalized precision medicine. Long-term culture, expansion and storage of organoids provide the necessary conditions for the establishm...
Focal stromal multinucleated giant cells, such as the benign multinucleated giant cells seen in subepithelial connective tissues of the genitourinary tract ▪ Areas of stromal mature fat, smooth muscle, or metaplastic cartilage51,52 ▪ Prominent myxoid stromal changes—when these are marked and mu...
Tumor segmentation is a process in radiomics analysis where the original medical image is converted into an extractable image. It involves identifying and delineating the boundaries of a tumor within the image, which can be challenging due to subjective variations, time-consuming manual segmentation, ...

¹Duke University Medical Center ²David Geffen School of Medicine at the University of California, Los Angeles First described by Berger in 1924, esthesioneuroblastoma (ENB) remains a rare sinonasal tumor believed to originate from specialized sensory olfactory cells. To date, the literature inclu...
Juxtapleural tumors are closely related to the pleura and chest wall and may originate from osseous structures, cartilage, soft tissue, muscles, nerves, or fat. Although imaging findings may overlap or be aspecific, some tumors may present with a particular imaging feature or specific clinical set...
Simple lipomas are comprised entirely of fat without any internal nodularity or thickened septations, although smooth thin (<2 mm) bands may be seen. The presence of internal fat stranding (“dirty fat”) or nodularity on STIR or contrast-enhanced imaging may indicate atypical lipomatous tumor...
Oral cancer is one of the most common malignant tumors of the head and neck, not only affects the appearance, but also affects eating and even endangers life. The clinical treatments of oral cancer mainly include surgery, radiotherapy, and chemotherapy.
