RESUMEN
Bioceramics include ceramic materials specifically designed for use in medicine and dentistry. These materials are mainly alumina, zirconia, bioactive glass, glass ceramics, coatings, composites, hydroxyapatite and resorbable calcium phosphates. Dental applications include dental implants, in periodontal treatment, alveolar ridge augmentation, maxillofacial surgery, pulp capping and apexification. The use of alumina and zirconia can be seen for prosthetic devices although calcium phosphate based materials are used for filling bone defects. Bioceramics are biocompatible, non–toxic, do not shrink and are chemically stable within the biological environment. Bioceramic sealers allow the enhanced use of bioceramics. The future of bioceramics is very promising. Recently, bioceramic putty has been introduced for primary teeth along with other fast repair materials.
RESUMEN
Concurrent or synchronous angiosarcoma (AS) of breast is a rarity. Specific recognition of this neoplasm in cytological specimens is difficult and conclusive diagnosis in the absence of ancillary methods is achieved only uncommonly. Herein, we present a case of bilateral AS of breasts in a 32-year-old lady diagnosed by fine needle aspiration (FNA) cytology, thus enabling a definitive surgical approach. This case report emphasizes that when aspiration smears show vasoformative features consisting of microacini, arborizing microtissue fragments and intracytoplasmic lumen against a bloody background, diagnosis can be made conclusively by FNA with immunohistochemical confirmation.
