ObjectiveTo discuss the CT manifestation and clinical significance of rare neoplasm in maxillary sinus, includingmalignant myoepithelioma, angioendothelioma, sarcoma of plasmacyte.
Primary mediastinal germ-cell tumors (GCTs) without gonadal involvement are rare and can be divided into benign mature teratoma and malignant seminoma or nonseminoma.
Conclusion PEA, a rarely seen disease,is hard to differentiate from synovioma, fibrosarcoma or giant cell tumors, whose diagnosis depends on pathological examination.
Methods X-ray and CT findings of one patient with surgically and pathologically proved benign cementoblastoma(BCB)in left mandibular region were analyzed together with review of the literature.
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.
