1/3. carcinosarcoma of the parotid gland with epithelial-myoepithelial carcinoma and pleomorphic sarcoma components.We report a case of true malignant mixed tumour (carcinosarcoma) of the parotid gland with epithelial-myoepithelial carcinoma and pleomorphic sarcomatous components in a 68-year-old woman. The pleomorphic sarcomatous component behaved aggressively with lymph node and distant metastases. The biological behaviour of the individual components in a malignant mixed tumour makes it difficult to diagnose. We could find no previous report of epithelial-myoepithelial carcinoma as a component of a carcinosarcoma of the parotid.- - - - - - - - - - ranking = 1keywords = behaviour (Clic here for more details about this article) |
2/3. Giant basal cell carcinoma of the thoracic wall: a case report and review of the literature.Giant basal cell carcinoma is a rare skin tumour with aggressive biological behaviour, and deep invasion and metastasis have been reported. The authors describe a giant basal cell carcinoma involving the anterior chest wall. The lesion infiltrated the mediastinum, occluding the left brachiocephalic vein. Vascular invasion caused venous occlusion affecting the left upper limb. Neither surgical treatment nor radiotherapy were practicable.- - - - - - - - - - ranking = 1keywords = behaviour (Clic here for more details about this article) |
3/3. Case report. Infiltrative fibromatosis: a rare cause of fatal haemorrhage.A case of infiltrative fibromatosis in a 25-year-old man is described. This is a rare, recurring tumour most commonly seen in the shoulder and pelvic girdles, whose behaviour seems to justify the opinion that it is a non-metastasizing, low-grade fibrosarcoma.- - - - - - - - - - ranking = 1keywords = behaviour (Clic here for more details about this article) |
