classification now incorporates these molecular insights, allowing for more accurate prediction of metastatic risk. The Role of the WHO Classification in Research and Education Beyond clinical use, the classification is a cornerstone
veillance on a global scale. **Guidance for Personalized Medicine:** Incorporation of molecular markers in the latest editions assists in identifying targetable mutations and informing novel therapeutic approaches. Evolution
hromophobe RCC: Chromosomal losses, mitochondrial abnormalities. Urothelial carcinoma: FGFR3 mutations, TP53 alterations. Incorporating molecular data improves prognostication and opens avenues for targeted therapies. Practical Approach
rs Malignant Mesothelioma (MM): The most significant primary malignant tumour of the pleura, with distinct histological subtypes and molecular features. Malignant Mesothelioma Subtypes The WHO recognizes three main histological subtypes, each with differing prognosis and therapeutic responses:
desmoid fibromatosis, nodular fasciitis. Malignant Tumors (Sarcomas) Capable of invasion, metastasis, and recurrence. Examples: liposarcoma, rhabdomyosarcoma, angiosarcoma. Diagnostic Approach to Soft Tissue Tumours Accurate diagnosis relies on a combination of cl
