ObjectiveTo discuss the CT manifestation and clinical significance of rare neoplasm in maxillary sinus, includingmalignant myoepithelioma, angioendothelioma, sarcoma of plasmacyte.
Conclusion PEA, a rarely seen disease,is hard to differentiate from synovioma, fibrosarcoma or giant cell tumors, whose diagnosis depends on pathological examination.
The malignant mesenchymoma is not rare actully,but owing to the one sidedness of sampling,it is always diagnosed pathomorphogically as one singletissue sarcoma.
Soft tissue sarcomas are a highly heterogeneous and polygenous group of tumor, and characterized by specific chromosome translocations and corresponding fusion genes.
The possibility of postirradiation sarcoma after radiation therapy should not be a major factor influencing treatment decision in the patient with breast cancer.
The authors suggest that goniotomy may benefit selected patients with idiopathic uveitic glaucoma or that associated with juvenile rheumatoid arthritis, sarcoidosis, or cataract surgery.
Granulocytic sarcoma (GS), also known as extramedullary myeloblastoma or chloroma is an unusual manifestation and represent soft tissue masses composed of immature cells of the granulocytic series.
Images 1, 2: 21st week of pregnancy. Transverse scans through the fetal thorax show tumoral mass at the level of the heart which turned out to be lipoblastoma.
