| Abstract | BACKGROUND: Laryngeal carcinosarcomas pose a significant diagnostic challenge to the pathologist; differential diagnosis needs histochemical and immunohistochemical investigations. MATERIALS AND METHODS: A retrospective review of charts of the pathology database was performed by a search for carcinosarcoma cases. Immunohistochemistry was performed on the representative paraffin blocks in all cases. RESULTS: This study included a total of 5 cases of carcinosarcomas of the larynx. The sarcomatoid component of the tumor was arranged in various patterns mimicking mesenchymal malignancies. Tumor cells were seen arranged in fascicles (a patient), in a storiform (3 patients), or in a solid (a case) pattern. The epithelial markers EMA and AE1/AE3 were positive in all 5 patients, as well as vimentin and CK34betaE12. DISCUSSION: Immunohistochemical studies of epithelial and mesenchymal markers (such as AE1/AE3, epithelial membrane antigens, vimentin, desmin, and S-100) are fundamental to diagnose the tumor, although they may widely vary. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
