Tumörform

Tumörform refers to the macroscopic appearance and shape of a tumor. It is a descriptive term used in pathology and oncology to characterize how a tumor presents itself to the naked eye. Tumor shapes can vary widely and can provide clues about the tumor's behavior, such as its growth pattern and potential for invasion. Common descriptors include nodular, fungating, ulcerated, polypoid, diffuse, and infiltrative. A nodular tumor typically forms a discrete lump, while a fungating tumor projects outwards with a cauliflower-like appearance. Ulcerated tumors have a surface defect, and polypoid tumors are finger-like projections. Diffuse tumors spread out without clear borders, and infiltrative tumors grow into surrounding tissues in an irregular manner. The study of tumorform is part of the gross examination of surgical specimens and can aid in diagnosis and treatment planning. It is a visual assessment that complements microscopic analysis.
